    Low-Pressure Stainless Steel Threaded Pipe Fittings

    Use these fittings in a low-pressure pipe line.

    Image of Product. Female x Male. Front orientation. Pipe and Fittings. Low-Pressure Stainless Steel Threaded Pipe Fittings, Union 90° Elbow Adapters, Male, Female, Threaded Fitting Connection.

    Female x Male

    Female x male 90° elbow adapters are also known as street elbows.
    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.

    Medium-Pressure Iron and Steel Threaded Pipe Fittings

    With better strength than our low-pressure iron and steel pipe fittings, these can handle medium-pressure applications. They are for use in noncorrosive environments.
