The Mosmatic WDRS Swivel 41.161 is a high-performance stainless steel swivel designed for demanding applications such as automatic car wash systems, industrial equipment, high-pressure hose reels, and high-flow setups. Engineered for durability and smooth operation, this swivel coupling delivers reliable performance in harsh environments where consistent rotation and leak-free operation are critical.
Featuring a robust dual bearing system with two radial ball bearings and an NBR O-ring seal, the WDRS 41.161 ensures smooth rotation, reduced wear, and long service life. Its stainless steel construction offers excellent corrosion resistance, making it ideal for continuous use with water, chemicals, and compressed air.
This model includes a Thread In of 3/8” NPTF and a Thread Out of 3/8” NPTM, with a nominal width of 3/8”, overall diameter of 1.77”, overall length of 4.13”, and height of 1.46”. Designed to handle pressures up to 3000 PSI and temperatures ranging from 40°F to 180°F, it supports media with a pH range of 3–12 and 10-micron filtered compressed air up to 290 PSI.
