If you only need to crimp a few Pex fittings and you don’t want to carry a large Pex crimper around, the Pex Pocket Crimper might be for you. Using a set of 10″ locking pliers, the Pex Pocket Crimper allows you to crimp fittings onto 3/8″, 1/2″, and 3/4″ Pex tubing.
The crimper is small enough to fit into tight places and it also separates into two pieces at the joint, allowing you to use it in cramped quarters.
To use the tool, prep the tubing, slip the crimp ring over the tubing, and insert the fitting into the tubing. Then place the crimper over the ring and squeeze the ends of the PexPocket Crimper with locking pliers. Finally, check your crimp with the supplied go-no-go gauge.
Manufactured in the US, the Pex Pocket Crimper will run you about $30 with $6 shipping and handling. If you’re interested in crimping larger sized PEX they also make a 1″ version which they ship for $41.
