    High-Pressure Iron and Steel Threaded Pipe Fittings

    Connect pipe in high-pressure systems. These iron or steel fittings are best for noncorrosive environments.
    Note: The maximum pressure listed for Class 3000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

    Union fittings separate into three pieces so you can access your line without unthreading pipe connections.
    304 Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.
    316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

    Union fittings separate into three pieces so you can access your line without unthreading pipe connections.
    304 Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.
    316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

    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.
