PEX installation seems so easy that it is hard to focus on small details. Improper crimps rarely leak short-term. Often, it takes a few years for leaks to develop. Unfortunately, if crooked, too tight or too loose rings cause leaks, the whole house might have to be re-piped to make it safe.

How long do PEX Clamps last?

ASTM International, a standards organization, requires that the life expectancy for PEX pipe be at least 50 years.

Can I use pinch clamps on PEX?

Using stainless steel pinch clamps, also referred to as ear clamps, are a great way to connect PEX pipe to PEX fittings. Connections made using SS Pinch Clamps with an interlocking design provide the same high integrity connection as a copper crimp ring connection.

Are PEX crimp and clamp fittings the same?

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.

A 3/8-inch line is sufficient for lengths up to 250 feet; 1/2-inch line will deliver adequate water pressure up to 350 feet; and 3/4-inch tubing is necessary to run a 500-foot line. Look for a maximum recommended lengths specification on the PEX packaging.
