    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.
    Hex-Drive Plugs
    Magnetic—Plugs with magnet attract metal debris that could otherwise damage your system.
    NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.
    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.

    Hex-Drive Plugs with Copper Washer
    Plugs with copper washer form a tight seal to prevent leaks. Also known as a crush washer, the washer compresses and deforms to fill gaps when tightened. Because it loses its shape when compressed, it’s not reusable. Made of copper, the washer resists rust. These plugs meet either DIN 908 or DIN 910, international standards for pipe plug dimensions.
    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.

    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.

    Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

    Precision Extreme-Pressure Stainless Steel Threaded Pipe Fittings

    Made to tighter tolerances than other stainless steel pipe fittings, these are also known as instrumentation fittings. The male threads are rolled for extra strength in extreme-pressure applications. Fittings are commonly used to connect equipment in gas and hydraulic fluid lines.

    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.

    Self-Draining Breather Vents

    Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain. They have a silicone O-ring above the threads for a tight seal. Install them at the lowest point of the enclosure. Breather vents meet IP66 for protection in washdown environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.
