PEX-AL-PEX Chamfering Tool

PEX-AL-PEX tubing contains a layer of aluminum embedded in the PEX. The aluminum serves as an oxygen barrier and allows the PEX to remain straighter. It also makes the tubing slightly thicker, so that standard crimp, clamp, or SharkBite fittings are not compatible. Compression or press fittings must be used with PEX-AL-PEX.

To prepare PEX-AL-PEX tubing for a fitting, a chamfering tool should be used. The tool reams the inside of the tubing, cleaning it and creating a beveled edge so that the fitting’s o-ring can set properly. For more information on PEX-AL-PEX products, visit
