    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.

    SAE High-Pressure Iron and Steel Threaded Two-Piece Pipe Flanges

    Combine an adapter with a two-piece pipe flange (sold separately) to build a customized flange connection. Also known as Code 61 split flanges, the two halves of the flange clamp around the adapter and bolt to another Code 61 flange. Flanges and adapters should be used in noncorrosive environments.

    Sanitary Split Sealing Grommets

    Image of Product. Front orientation. Grommets. Sanitary Split Sealing Grommets.
    These grommets prevent contamination around wire, cable, cords, pipe, and tubing you’ve already installed. Often used in food-and-beverage and pharmaceutical plants, they're made of nonporous silicone and smooth, corrosion-resistant stainless steel to prevent bacteria from building up. To install, trim along the ridge to create the hole diameter you need. Then wrap the grommet around your line, clamp the staples to seal the grommet, and screw the flange onto the surface.

    Solid—Recessed

    Block the gap between a sprinkler head and the wall or ceiling. Also known as escutcheons, these plates make sure rising heat sets off your sprinklers instead of escaping through the gap.
    Solid—Solid plates must be installed before a sprinkler head.
    Recessed Mount—Recessed plates sit flush against a surface for a clean look. They have a flat outer ring and an inner ring that extends into the wall or ceiling.
