Mosmatic DGL Series Swivel Joint Model 31.053 – Dual-Port Industrial Rotary Union

Description

The Mosmatic DGL Swivel 31.053 is a high-performance brass, nickel-plated swivel engineered to manage both thrust and radial forces in high-flow, high-pressure cleaning systems. Ideal for automatic car washes, hose reels, and industrial wash systems, this swivel ensures reliable, maintenance-free operation even in the most demanding environments.

Equipped with a triple bearing system—two radial ball bearings and one thrust ball bearing—the DGL 31.053 delivers consistent rotation and extended durability. The O-ring NBR seal system provides robust leak protection, with optional EPDM or FKM seals for enhanced chemical resistance. Corrosion resistance, compact form, and a bulkhead fitting design make this swivel a go-to solution for professionals seeking quality and precision.
