3/8 inch x 1/2 inch Copper 90° PEX Crimp Stub Out – Closed End Fitting for Fixture Supply Terminations

This 3/8 inch x 1/2 inch copper 90-degree stub out is a lead-free fitting designed to provide a stable, terminated point for PEX tubing installations behind walls. Its closed end allows for fixture connection preparation while maintaining system pressure integrity until final hookup. The fitting features a crimp PEX connection and a formed copper bend for directional change and anchoring.

Commonly used in concealed rough-in plumbing, this fitting supports efficient transitions from horizontal or vertical PEX runs to fixture supply points such as lavatories, water closets, or kitchen sinks. Its rigid form factor and 90-degree angle assist with layout consistency and bracketing.

Installation Considerations

Designed for integration in wall cavities, this fitting must be secured using brackets or stub-out supports to maintain positional integrity. PEX tubing is inserted into the crimp inlet and secured with a tool-calibrated crimp ring. The closed-end termination permits pressure testing of the supply system prior to fixture installation or trim-out. Final connection involves trimming the cap or removing the closed end.
