How to use
To install the TDM Brass 1435E, ensure that the pipe ends are clean, deburred, and properly prepared for connection. Apply an appropriate thread sealant or PTFE tape to the threaded portion to enhance the seal. Align the fitting with the pipe and tighten it using a suitable wrench, ensuring not to overtighten, which could damage the threads or the internal sealing surfaces. Once installed, perform a pressure test to verify that the connection is completely leak-free before fully commissioning the system.
