Installation tips
- For End 1 (Expansion PEX): use a compatible expansion tool to expand the ½ in. PEX, then insert into the End 1 port. Allow the material to cool and verify a secure fit.
- For End 2 and End 3 (Barb): slide ½ in. PEX tubing over the barb connection and secure with appropriate clamps or brackets designed for barb fittings to ensure a leak‑tight seal.
- After assembly, perform a pressure test up to 200 psi and inspect all connections for any signs of leakage. If needed, re‑tighten clamps on barb fittings.
