Mosmatic DYCI Swivel - 55.203 - M21x1.5M to G3/8"M

The Mosmatic 55.203 DYCI Swivel is a high-quality, stainless steel swivel engineered for high-flow, high-pressure, self-rotating applications including surface cleaners and parts washers. It’s designed for continuous operation in demanding environments, delivering smooth, efficient rotation and long-lasting durability.

This model features a triple bearing system - with two radial ball bearings and one thrust bearing - to ensure stability and performance at high speeds and pressures. A carbide seal system provides reliable leak protection, and weep holes offer early detection of seal wear or failure. With a pressure rating of 5000 PSI, temperature tolerance up to 250°F, and speed capacity of 2000 RPM, this swivel is built for professional-grade results.
