Jacketed Swivel Joints

Any of OPW Engineered Systems’ fabricated steel or stainless-steel swivels
can be ordered jacketed. Jacketed swivels are commonly used in
applications where relatively high temperatures must be maintained, such
as asphalt, sulfur, waxes and resins.
OPW jacketed swivels feature full steel jackets on the elbow portions only.
Conductive heat from the jacketed elbows of the swivel joint provides
sufficient heat to the seal area, which is generally field-insulated. For
applications considered highly critical, the seal area of the joint can also
be jacketed. Standard steam connections are 3/4" FNPT.
Mediums other than steam can also be re-circulated through OPW
jacketed swivels to heat or cool products, such as oil, water and glycol,
among others.

 ENDURA™
Dual Split Flange Swivels
(8400 and 8900 Series)
The OPW Engineered Systems’ ENDURA™ swivel line
represents leading innovation in swivel technology.
Specifically designed for the transfer o
­ f hazardous
materials such as LPG, acids, solvents, petrochemicals
and other toxic fluids, ENDURA™ sets the industry
standard in swivel performance and cost-effective
operation. Featuring heavy-duty flanged construction
and available in a variety of materials.

Benefits
Endurance –
heavy-duty construction and unique design features
result in long-life, hassle-free performance.
Smooth, Easy Operation –
the sealed, one-piece deep-groove dual ball bearing
assembly ensures smooth and easy rotation.
Improves Uptime Performance –
the simple, three-piece design allows for the quick-
est and easiest disassembly and repair in the industry,
which means less downtime, less labor and less cost.
Lowest Overall Cost of Ownership –
heavy-duty construction ensures long-life reliability
while the unique design features allow for
cost-effective preventive maintenance servicing and
the easiest, most cost-effective seal and bearing
replacement of any swivel. Optimized performance,
downtime prevention, and reduced maintenance
time and costs make this the best overall swivel value
in the industry.

Features
360º Rotation –
Leak Detection/Purge Port
full range of motion for ease of use.
Deep-Groove Replaceable Dual
Sealing Flange
Ball Bearing Technology –
a precision-engineered, one-piece, ball bearing assembly
eliminates the need for individual balls. If required,
bearing replacement is quick and easy; simply replace the
old bearing chamber with a new one. The ENDURA™ DSF Environmental Main Seal
8900 Series features a 316 Stainless Steel replaceable dual Seal Back-Up Seal
ball bearing chamber.
Redundant Seal System –
incorporates a main seal, back-up seal, environmental seal
and leak detection. If the main seal ever leaks due to
normal wear, the back-up seal contains the fluid. Leakage
is then channeled to a leak detection port in the side of the
swivel to provide a visual indicator that service is required
so the seals can be replaced. The environmental seal
provides a third layer of protection, preventing liquid from
entering the environment. Seal materials include Buna-N,
Viton®, EPT, Kalrez®, Chemraz®, Silicone, and Food Grade.
Built-In Leak Detection –
a visual indicator, in the form of a leak detection port in the Sealed, Deep-Groove Sealing Flange
side of the swivel provides a quick and easy way to monitor Dual Ball Bearing
seal leakage so preventive maintenance can be performed Chamber
before a problem arises. The leak detection port also can
serve as a purge port, permitting use of a blanket of inert
gas to prevent product from escaping into the environment.
Versatility –
available in 2", 3" and 4" sizes, and in a variety of
construction materials, including carbon steel, stainless
steel, Hastelloy®, Alloy20®, Monel® and other exotics.

3000RK-0X01
OPW Engineered Systems has kits available to rebuild all swivel joints. The kits Fluorocarbon 3000RK-0X02
contain all the necessary parts to replace the wear parts. Before installing new seals,
PFA-Silicone 3000RK-0X03
care should be taken to see that all machined surfaces are clean and that there are no
nicks, scratches or burrs. Consult your local distributor for the proper kit. EPDM 3000RK-0X04

Lubricants X = Swivel Size

OPW swivel joints should be lubricated periodically, depending on service and operating conditions. For normal
operation, annually is sufficient. Frequent lubricating may be required when service is severe, such as high
temperatures, heavy loads, or constant rotation.

Specifications
All OPW swivel joints are full bore schedule 40 construction with short radius elbows, except 6", 8" and 10" fabricated steel and
stainless-steel swivels which have long radius elbows. Ball bearing raceways and sealing surfaces in all swivels are precision machined
and micro-finished to ensure friction-free operation and superior sealing characteristics. All steel and ductile iron swivels are painted
blue. Detailed specifications by series are as follows:
3200 Series (Cast Steel, High-Pressure)
Bodies and tails of cast 1040 carbon steel with hardened raceways. Ball bearings are precision-ground steel. Buna-N main O-ring seal
with Teflon® back-up ring, and Buna-N O-ring dust seal are standard.
3300 Series (Cast Bronze)
Bodies and tails of hard, wear-resistant cast bronze (ASTM B62-83600). Precision-ground steel balls, Buna-N O-ring main seal and felt
dust seal are standard. 1" size has Buna-N O-ring dust seal.
3400 Series (Fabricated Steel)
Bodies and tails of 1040 carbon steel with hardened raceways. Welded construction; 100% penetration welding by welders certified
to ASME Boiler and Pressure Vessel Code, Section IX. Precision-ground steel balls, Buna-N O-ring main seal, Buna-N O-ring dust seal.
Standard flanges are ASME 150 lb. raised face type.
3600 Series (Cast Aluminum)
Bodies and tails of cast A-356 high-tensile strength aluminum. Precision-ground steel balls, Buna-N O-ring main seal, and felt dust
seal are standard. 1" size has Buna-N O-ring dust seal. Flanges are dimensionally compatible to ASME 150 lb. flat face configuration.
3700 Series (Cast Stainless Steel)
