Mosmatic DYCI Swivel - 55.163 - 3/8"NPTF to G3/8"M

The Mosmatic 55.163 DYCI Swivel is a premium stainless steel swivel built for high-flow, high-pressure, self-rotating applications such as surface cleaners and parts washers. Precision-engineered for performance and durability, this swivel is ideal for use in commercial and industrial cleaning systems.

It features a triple bearing system - comprising two radial ball bearings and one thrust ball bearing - for stable, smooth rotation. A carbide seal system ensures long-lasting sealing performance, while integrated weep holes provide early warning in the event of seal failure. With a pressure capacity of 5000 PSI, it’s designed to operate efficiently at up to 2000 RPM and 250°F, delivering consistent, high-performance rotation.
