    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.

    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.

    Low-Pressure Iron and Steel Threaded Pipe Fittings

    Use these fittings for low-pressure applications in noncorrosive environments.
    Hex-Drive Plugs with Copper Washer

    Male

    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.
