PEX fittings connect PEX tubing to other pipes, fixtures, valves, manifolds, or sections of PEX tubing. The most common PEX fitting types by shape include elbows, tees, couplings, adapters, reducers, plugs, caps, stub-outs, and manifolds. But there is an important distinction that often causes confusion: a fitting’s shape is not the same thing as its…
Plastic and brass PEX fittings can both be reliable choices. The better option depends on the fitting design, connection method, water conditions, flow requirements, installation, and product certification—not simply whether the fitting is plastic or brass. For most residential PEX plumbing, high-quality plastic fittings made from engineered polymers such as PPSU can offer excellent corrosion…
PEX pipe fittings connect, redirect, branch, or transition PEX tubing. Common types include elbows, tees, couplings, adapters, valves, and manifolds. Common options include elbows, tees, couplings, adapters, valves, and manifolds, while connection methods include crimp, clamp, expansion, press, and push-to-connect systems. The tricky part? Not every PEX fitting works with every tubing or connection system….
