    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.

    Extreme-Pressure Stainless Steel Threaded Pipe Fittings

    With the strength to handle extreme pressures, these fittings can be used to connect equipment in hydraulic fluid lines.

    NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.
    UN/UNF (SAE Straight) Thread—Also known as O-ring boss threads.
    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.

    Straight Reducing Adapters
    NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.
    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.

    NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.
    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.
