This connection ensures its users that their system will provide safe, dependable and consistent service for decades of successful use.
Making a ProPEX connection is simple. First, place a ProPEX Ring over the end of PEX tubing and expand the tubing and ring with an expansion tool. Then, place the expanded tubing and ring over a fitting. All that’s left is for the tubing and ring to shrink around the fitting as they return to their original shape.
