Yes, you will need pipe cutters, a deburring tool, and two wrenches (one to hold the fitting body, one to tighten the nut) for proper installation.

Compression rings are designed to deform and create a seal upon initial tightening. It is generally recommended to use a new compression ring for each installation to ensure a reliable and leak-free joint.

Compression fittings use a nut and ring to mechanically grip and seal onto the pipe, requiring tools for installation. Push-fit fittings use internal O-rings and a gripping mechanism that allows them to be pushed onto the pipe by hand, often offering faster installation.

Ensure the pipe is clean and fully inserted into the fitting. Re-tighten the compression nut according to installation guidelines. Check that the compression ring (olive) is correctly seated and not damaged.

Verify that the nut and fitting threads are clean and free of debris. Ensure the correct size fitting is being used for the pipe diameter. If the pipe is deformed, it may need to be re-cut.

Confirm the pipe end is cut square and has no burrs. Check for any internal obstructions within the fitting body. Ensure the correct pipe material is being used and it is not excessively out of round.
