The die cast construction provides consistent dimensional accuracy and adequate strength for standard plumbing service conditions.

This jam nut is suited for drain line assemblies where a 1-1/2 inch OD tube connection must be secured at a fixture outlet, trap adapter, or similar fitting. It is commonly used by licensed plumbers during fixture installation or replacement work under kitchen sinks, lavatories, and utility sinks.

Installation Notes

Installation is performed by licensed plumbers or qualified service technicians. Shut off water supply and clear the drain line before servicing the fitting. Hand-tighten the jam nut first to confirm thread engagement, then snug with pliers or a strap wrench — avoid overtightening die cast hardware, which can crack under excessive torque. Work performed on drain, waste, and vent systems should conform to the applicable edition of the International Plumbing Code or local authority having jurisdiction.
