    Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

    Extreme-Pressure Iron and Steel Threaded Pipe Fittings

    The strongest steel fittings we offer, these can withstand extreme-pressure applications.
    Note: The maximum pressure listed for Class 6000 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.

    Metric Lead Screws and Nuts

    Image of ProductInUse. Front orientation. Contains Inset. Lead Screws and Nuts. Metric Lead Screws and Nuts.
    Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. To ensure compatibility, please select components that have the same thread direction, size, and number of thread starts. Class 7e and 7H components are compatible.
    Flange Nuts—Right-Hand Thread
    Image of Product. Top orientation. Contains Annotated. Lead Screws and Nuts. Metric Lead Screws and Nuts, Flange Nuts—Right-Hand Thread.
    Flange nuts move objects along the length of a lead screw. They have a wide machinable flange for custom mounting.
    932 Bearing Bronze—932 bearing bronze components are more wear resistant than brass components. They have good machinability and fair corrosion resistance.
    Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

    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.
    Fluoroelastomer—These gaskets resist a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.

    Low-Pressure Aluminum Threaded Pipe Fittings

    In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications. To prevent cracking, do not tighten more than a 1/4-turn past hand tight.

    The contact surface on fittings with a flange extends beyond the external hex drive.
    Anodized Aluminum—Anodized and powder-coated fittings have a decorative matte black finish.
    DIN 3852—DIN 3852 fittings meet DIN standards for mating surface outer diameter. They have a Buna-N rubber gasket that resists grease, hydraulic oil, and motor oil—plus mild chemicals and water. The gasket stays in a groove undercut in the mating face, which prevents it from dropping out and from extruding when fittings are tightened.

    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.
