How to use
To install the TDM Brass 1665 compression elbow, ensure the pipe ends are cut cleanly and are free of burrs or debris. Slide the compression nut and the ring onto the pipe, then insert the pipe fully into the elbow fitting. Tighten the nut onto the fitting body using an appropriate wrench. The self-tapping mechanism will engage as the nut is tightened, creating a secure and watertight seal. Always verify that the connection is tight and perform a pressure test before finalizing the installation.
What to consider before purchase
Verify the outer diameter of your existing piping system
Ensure the installation space allows for wrench access
Check compatibility with the specific pipe material being used
Usage recommendations: For optimal performance, ensure that the pipe is inserted straight into the fitting to prevent misalignment. Do not overtighten the compression nut, as this may damage the internal sealing components.
