Endura™ Benefits and features


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 quickest 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 include:

360° Rotation Full range of motion for ease of use. Deep-Groove Replaceable Dual Ball Bearing Technology – a precision-engineered, one-piece ball bearing assembly means there are no individual balls to deal with. If required, bearing replacement is quick and easy; simply replace the old bearing chamber with a new one. The ENDURA™ DSF 8900 Series features a 316 Stainless Steel replaceable dual 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.


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. 500 PSI Pressure Rating
