Mosmatic DGL Rotary Swivel Union – Model 31052 with G1 1¼” NPTF and G2 1¼” NPTF Ports

Description

The Mosmatic DGL Swivel 31.052 is a brass, nickel-plated swivel engineered for high-flow and high-pressure applications such as automatic car wash systems, hose reels, and industrial cleaning setups. Designed to withstand both thrust and radial forces, this swivel offers optimal performance in continuous-use operations.

With a triple bearing system (2x radial ball bearings, 1x thrust ball bearing) and a robust O-ring NBR seal system—with optional upgrades to EPDM or FKM—this swivel ensures longevity, smooth rotation, and corrosion resistance. It features a bulkhead mount, is maintenance-free, and built for maximum reliability and durability.
