    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 Threaded Pipe Fittings

    Use these fittings in a low-pressure pipe line.
    90° Elbow Connectors
    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.

    Medium-Pressure Stainless Steel Butt-Weld Pipe Fittings

    Also known as Schedule 40 fittings, these have thicker walls than our thin-wall stainless steel unthreaded butt-weld fittings. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow.

    304/304L Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

    Stub-End Straight Adapters

    Straight Adapter

    Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

    304/304L Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.
    316/316L 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.

    Straight Adapter

    Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

    Premium Low-Pressure Stainless Steel Threaded Pipe Fittings

    Unlike other stainless steel fittings, these are cast in the U.S. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition. All fittings except plugs adhere to ANSI/MSS SP-114 standards for heat treating, material thickness, and marking. It’s the highest quality standard for Pressure Class 150 low-pressure stainless steel fittings. They also meet either ASTM A351 or A479 requirements for parts that will be used in pressure systems. These stainless steel fittings are more corrosion resistant than steel fittings, and almost as strong.
    Material Certificate Icon
    Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

    High-Pressure Stainless Steel Socket-Connect Pipe Fittings

    Forged for excellent strength, these heavy duty socket-connect fittings stand up to high-pressure applications. They are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection.

    Low-Pressure Stainless Steel Press-Socket Pipe Fittings

    Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat. Fittings have an internal stainless steel gripping ring and rubber O-ring that create a seal when crimped. They are designed to leak if fittings have not been crimped; a colored dot marks the leak path so it's easy to spot unsealed connections. All of these fittings are made of 304 stainless steel to resist corrosion from frequent exposure to water and fuels. They’re often used for water processing lines, heating and cooling systems, and fuel lines. They are comparable to Viega MegaPress fittings. Fittings meet ANSI/ASME B31 code requirements for use in pressure piping systems.
