    About Pipe and Fittings
    industrial info icon

    Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

    Low-Pressure Stainless Steel Press-Socket Pipe Fittings

    Press these fittings onto stainless steel pipe for permanent, leak-tight connections. Faster than threading or welding and no heat required, install them with a crimping tool. An internal stainless steel gripping ring and rubber O-ring create a seal when crimped. Designed to leak if fittings aren’t crimped, a colored dot marks the leak path so it's easy to spot unsealed connections. Comparable to Viega MegaPress fittings, they’re often used for water processing lines, heating and cooling systems, and fuel lines. Fittings meet ANSI/ASME B31 code requirements for use in pressure piping systems.
