Mosmatic DGG Series Swivel Joint 33.153 – Dual-Port Rotary Union Featuring G1 3/8″ NPTF Inlet and G2 3/8″ NPTM Outlet

Description

The Mosmatic DGG Swivel 33.153 is a high-precision, nickel-plated brass swivel designed for self-rotating, high-pressure cleaning systems. Built for performance and longevity, it features a triple bearing system—two radial ball bearings and one thrust bearing—for smooth, consistent operation in demanding environments.

This swivel includes an O-ring NBR seal system with optional upgrades to EPDM or FKM for specialized chemical resistance. The corrosion-resistant design, bulkhead mounting, and maintenance-free operation make it ideal for industrial cleaning setups.
