Mosmatic Swivel – 58.351 – 1/4" NPTF x 1/4" NPTM – DYF 90° – 4000 psi – 13.0 oz

The Mosmatic 58.351 DYF 90° Swivel is a high-performance rotary union with a 90-degree elbow design, ideal for compact installations or where angular hose redirection is required. With a 1/4" NPTF (female) inlet and 1/4" NPTM (male) outlet, it enables smooth 360° rotation at high pressures, reducing hose stress and enhancing durability.

Constructed from nickel-plated brass, it features a carbide seal, sealed ball bearings, and weep holes for visual seal failure indication. Designed for pressures up to 4000 psi, it’s perfect for pressure washers, mobile equipment, and industrial spray systems.
