PEX crimp and PEX clamp connections use the same fittings, normally referred to as “crimp” or “barbed” PEX fittings. Each method requires a different tool and a different type of ring, but the styles are similar enough that PEX newcomers frequently wonder which method is preferable. Crimping and clamping create equally reliable seals that will not leak when performed properly. The choice between crimping and clamping should ultimately come down to personal preference, although there are a few pros and cons to keep in mind.
Stainless steel clamp rings resist corrosion more effectively than copper crimp rings, which can be a major benefit in direct-burial applications. PEX clamps also tend to be easier to remove. Since only a piece of clamp rings must be compressed in order to make a connection, a single clamping tool works with multiple pipe sizes. Although successful clamp connections can be confirmed based on the release of the ratchet tool, crimp fittings can be checked with a go-no-go gauge long after the original connection was made. Crimp rings and components are generally more readily available than their clamp alternatives.
