Mosmatic DKS Swivel - 70.051 - G1 M21X1.5F to G2 1/4"NPTM

The Mosmatic DKS Swivel Coupling 70.051 is a high-performance, nickel-plated brass swivel designed for high-pressure cleaning and hose connection systems. Engineered with a single thrust ball bearing and a precision ceramic seal system, it ensures smooth rotation and leak-resistant operation. A built-in flange allows for easy installation, while integrated weep holes provide early warning of seal failure to prevent downtime.

With a high-pressure capacity of up to 3600 PSI and a max temperature tolerance of 250°F, this swivel coupling is built to withstand rigorous industrial use. It features a quick-connect M21x1.5 F thread in and a ¼” NPTM thread out, offering compatibility across a range of applications. Supporting a nominal width of ¼”, and a max speed of 30 RPM, it’s optimized for pH 3–12 media and 10-micron filtered compressed air up to 290 PSI.
