Plugs (PEX x Stop)

Brass PEX Plugs are used to permanently or temporary cap off the ends of the PEX tubing for purposes such as pressure testing. They can also be used to prevent dirt, dust and debris from entering the open ends of PEX tubing during construction. These PEX fittings are compatible with crimp or clamp connection systems.
Typical testing pressure for PEX plumbing systems is at least 100 psi and can vary depending on local code requirements.

Typical testing pressure in PEX radiant heating systems can be from 50-100 psi, or x2 times the operating pressure (refer to local code requirements).

The use of water for pressure and leak testing purposes can be impractical, especially during winter season, when water can freeze inside the pipes.
