OILCO

All OILCO swivel joints are machined to a specifically controlled tolerance and tested throughout the assembly process. All swivel joints are available in carbon steel,
stainless steel T-316, or aluminum material. Either manufactured or cast. OILCO manufactures the broadest range of swivel joints in the industry; "O" ring, "V" ring,
split flange (either in "O" ring or "V" ring), both single and dual Timken® Roller Bearing, and removable seal design. Every swivel joint OILCO makes can be custom
tailored to the required specifications. This includes any special interior and exterior treatments and coatings, prepped for oxygen service, plugged for submerged
service, and special lubrication. Even radical individual design requirements can be included to any portion of the OILCO swivel joint line of products. Packing seal
material is Buna-N (standard) but Viton, Teflon®, Nitrile, Kalrez®, Chemrez®, EPDM and EPR are available.

The OILCO 80 Series is a heavy duty, leak proof construction and low maintenance joint. Flow restrictions and

Series swivel joint is a leak proof, low maintenance design. It has widely spaced ball races allowing for better
alignment and longer packing life. The single point seal will operate under both a vacuum and a pressure
environment. It can be cleaned and treated for use in oxygen transfer, food grade use, or other commercial needs.

Designed to be a light weight, sturdy, entry model swivel joint, the cast aluminum 880 Series includes all the
traditional industry requirements in an affordable unit. Standardized features include full rotation along the
swivel plane, wide ball race spacing for increased load carrying capacity, and precision milled pressure seal
and dust seal surfaces. A single "o" ring design with available compounds of Buna-N (standard), Viton,
Teflon®, Nitrile, Kalrez®, Chemrez®, EPDM and EPR are available. Available from 2" to 4" sizes, with either
threaded or flanged connections. Optional coatings are available upon request, or swivel joints can be left with
a natural cast finish. A primary loading arm component, the 880 Series swivel joints offer the versatility of the
OILCO line at a competitive price. With proper installation and maintenance, these swivel joint can be in the field
for years with problem freeservice. Repair kits are readily available for all sealing compounds.

The 90 Series swivel joint is designed with a three "V" ring seal configuration that is spring loaded and self adjusting for normal
wear. The incorporation of these "V" rings maintains a constant optimal pressure, securing a reliable seal long after conventional
single rings or compression seals may be compromised.The 90 Series is available in carbon steel, stainless steel T-316, and
aluminum. Sizes range from 1 1/2" to 12" in all materials. All styles are available in flanged, threaded, butt-weld ends, or even
socket ends. Packing seal material is Buna-N (standard) but Viton, Teflon®, Nitrile, Kalrez®, Chemrez®, EPDM and EPR are
available. Most commercial concerns, through over 50 years of field research and testing have been addressed by the OILCO 90
Series. By far, this swivel joint covers the widest range of production and safety considerations in the market today.

The 1400 and 1900 Split Flange Series adopts the criteria of the "O" ring swivel and offers it in a removable seal version. It is
a ball bearing, single point seal design with dust seal backup. The split flange series is available in carbon steel, stainless steel
T-316, and aluminum. Sizes range from 11/2" to 6" in all materials, and up to 18" in carbon steel and stainless steel. All styles
are available in flanged, threaded, and butt-weld ends. Packing seal material is Buna-N (standard) but Viton, Teflon®, Nitrile,
Kalrez®, Chemrez®, EPDM and EPR are available. The split design of the body cavity allows for easy in-field service without
having to remove the ball bearings. This greatly reduces the risk of maintenance error, while assuring proper alignment.
Further, the pressure seal has been positioned in such a manner that replacement time is considerably reduced. The Split
Flange Series can be lubricated in various manners enhancing the versatility of application. It can be cleaned and treated for
use in oxygen transfer, food grade use, sealed for submerged service, or other commercial needs.

The OILCO 2000 Series offers the best load carrying capacity in the industry. Unequalled in durability and overall moment
ratings, combined with virtually friction free movement and minimal seal wear, there is simply no other swivel joint that
measures up to its performance level. Timken® roller bearings are proven stronger than any other conventional bearings.
And put inside the precision CNC milled 2000 Series swivel joint spool, permanent alignment is assured. The bearings are
guaranteed by OILCO for the life of the joint (subject to proper installation, operation and regularly scheduled maintenance).
The 2000 Series is offered in carbon steel, stainless steel T-316 and aluminum. Packing seal material is Buna-N (standard)
but Viton, Teflon®, Nitrile, Kalrez®, Chemrez®, EPDM and EPR are available. The 2000 Series has a wide range of
availability - 2" through 12". And all styles are available in threaded, flanged, and butt weld connections.

This popular riser swivel joint is precision engineered and built of the finest materials to give long life, trouble free service
under the most extreme conditions. It is the most commonly utilized swivel joint for unsupported bottom loading assemblies.
The 857 Series comes standard with Timken® roller bearings that afford a friction free movement in the horizontal plane. The
sealing surface is maintained by a CNC milled collar unit that features a double "O" ring design over a polished sleeve, which
can be replaced within 15 minutes while never having to dismantle the loading arm assembly. The Model 857 riser swivel joint
is constructed of machine milled carbon steel. The sealing chamber is protected by a high density plastic shield. Packing seal
material is Buna-N (standard) but Viton, Teflon®, Nitrile, Kalrez®, Chemrez®, EPDM and EPR are available. Standard
configuration is a style 20 with 150# raised faced, flanged ends. It is offered in 4" size.

The Low Torque ("LT") model swivel joint is a specifically conditioned 90 Series swivel joint that reduces torque up to
65% more than any other conventional joint. Uses of the LT Series are where chinking of hoses or unnecessary
wear are of crucial concern. The low torque swivel can be broken with a minimal amount of manual pressure,
assisting in ease of use for the operator. The 90 Series Low Torque is vital to sensitive operations. The application of
the low torque option for the 90 Series swivel joint is for the entire nominal size range. Following the CNC milling
stage, the spool sleeve is polished on a lathe and turned to an extra smooth surface. The body portion receives a
specifically tailored honing. And the swivel joint utilizes a specific low friction graphite lubricant. This process is also
not limited to carbon steel units, but can be applied to both aluminum and stainless steel assemblies as well.

Expanding the already well known 1400 and 1900 Split Flange Series, OILCO increased the overall dimensions of
the units to accommodate many of the mainstream pipeline sizes. These swivels have widely spaced ball races
allowing for better alignment and higher moment load. The single point seal will operate under both a vacuum and
a pressure environment. The large size Split Flange Series is offered in both carbon steel and stainless steel
T-316. In smaller sizes, a 3rd raceway has been machined into the swivel and the triple spread has been moved
to the maximum allowable width to provide best carrying capacity and increased alignment. The ball chambers
are CNC milled and then polished to specific tolerances to ensure load carrying capacity and rotation throughout
the operational life of the swivel joint. Packing seal material is Buna-N (standard) but Viton, Teflon®, Nitrile,
Kalrez®, Chemrez®, EPDM and EPR are available.

Swivel joints manufactured in each of the major configurations in conjunction with the torsion spring
counterbalance or spring-matic unit. Each unit (i.e. - the single spring Model 641, the double spring Model 640, the
double-double spring Model 645, and the 1853-M Spring-matic Cylinder) is available for mounting on every style
50 or style 70 swivel joint. Every swivel joint configuration is also available with any number of inlet and outlet
combinations; male threaded, flanged, or female half coupling. OILCO can design the counterbalance swivel joint
units to be piggable (as seen to the right in the steam jacketed model), welded construction, or engineered to
required specifications by the customer to meet project needs.

Internal product lines can handle 500 psi while the steam chambers can work up to a range of 150 psi. The swivel joint
packing seals are able to withstand temperatures of up to 600 F. All internal elbows are long radius and standard weight,
allowing the assembly to be piggable when required. The incorporated joints are adaptable to suction or pressure lines with
standard packing seals. Constructed of a lighter gauge material on the exterior of the unit, a standard jacket will allow
steam to circulate evenly in order to preclude binding of the product. The external jacketing covers the elbow, but also the
entire ball race swivel area, providing positive rotation at all times. Every assembly is manufactured with long radius elbows
to allow the application to be piggable. These steam jacketed swivel are used for such viscous materials as petroleum
products, asphalt, tars, heavy oil, liquid sulphur, chemicals, and food products. Steam jacketed swivels are available in
sizes ranging from 2" to 10" and are constructed from carbon steel, stainless steel, or aluminum. Packing seal material is
Buna-N (standard) but Viton, Teflon®, Nitrile, Kalrez®, Chemrez®, EPDM and EPR are available.

By isolating the critical areas of the sealing service, OILCO managed to develop a process that mates the benefits of
stainless steel, while keeping the cost of the unit down to a more manageable level. The result was the stainless steel
insert swivel joint. These swivels are dimensionally identical to their carbon steel and stainless steel counterparts, but
utilize the necessary aspects of each material to prolong the seal life and seal area integrity. The development of the
stainless steel inserts for use in the 90 Series swivels has increased the life expectancy of the standard carbon steel
units, while not forcing the consumer to rely solely on the markedly higher priced full stainless steel T-316 version.

This unique ability to customize an already diverse swivel joint line is what truly marks the innovative side of
OILCO and its product capabilities. Ranging from special mounting circumstances, to epoxy coating, to
modified handling and insertion, OILCO has the ability to manufacture any swivel joint necessary to fulfill
project requirements. It is through the ability to restructure the manufacturing and assembly process, that
OILCO can continually alter the project to suit tedious requirements or otherwise rare engineering conditions.
Regardless of core differences in unit design, simple exterior coating, dated reproduction work, or complex
"one-off" innovations, OILCO has the tradition and desire to satisfy those needs.
