Step 7 · Install the New Angle Stop
Take your new angle stop and disassemble the compression fitting. Slide the new compression nut onto the cleaned pipe first, ensuring the threads face towards the end of the pipe. Next, slide the new brass ferrule onto the pipe. Push the body of the new angle stop onto the pipe until it seats firmly against the ferrule. The pipe should go about 1/2 inch into the valve body. Hand-tighten the compression nut onto the valve body until it is snug.
