How Brass Fittings Connect with PEX Tubing

Brass PEX fittings are designed to fit perfectly with PEX tubing. The two main connection methods are crimp and clamp. Both use a metal ring to compress the tubing over the fitting. This creates a watertight seal that withstands pressure and temperature changes. Brass barbs grip the inside of the PEX tube securely. When installed properly, these joints are strong and long-lasting. Another method is the push-to-connect system. It allows the fitting to lock into the tubing without special tools. All connection types offer secure, leak-free performance.
