    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.

    Fiberglass Pipe Flanges for Chemicals

    Reinforced with layers of fiberglass, these flanges are stronger and more durable than our other pipe flanges for chemicals. They handle a wide range of acids and other corrosive chemicals used in applications such as metal surface treating and plating solution lines. Bolt two same-size flanges together with a gasket (not included) to create an access point within a line. Flanges meet ASTM D4024 for product dimensions, performance, and material quality.
    To install, sand the inside of flanges and end of pipe to remove the surface finish. Mix adhesive (sold separately) until the color is uniform and there are no streaks. Place a thin layer of mixed adhesive approximately 1/8" thick on the sanded area of the pipe and 1/16" thick on the inside of the flange. Push the flange onto the pipe until it is fully engaged. Make sure to align the bolt holes prior to installing to minimize rotation after the flange is installed. Wrap the adhesive-curing heat cable (sold separately) around the pipe and flange at the joint. Do not overlap the tape. Once you have waited the full cure time, the pipe and fitting will be ready to use.

    Leak-Detecting Pipe Flange Covers with pH Patch

    Image of ProductInUse. Front orientation. Leak-Detecting Pipe Flange Covers. Leak-Detecting Pipe Flange Covers with pH Patch.
    When a tiny amount of liquid makes contact with the pH patch, it changes color to indicate a leak. Patch is orange when neutral. The wrap-around design of these covers contains acid and caustic pipe leaks, protecting personnel and equipment.
    PTFE-Coated Fiberglass—PTFE-coated fiberglass covers are highly resistant to acids, alkalies, and most chemicals except hydrofluoric acid.

    Flange Nuts

    Image of Product. Front orientation. Flange Nuts. Flange Nuts.
    No need for a separate washer—these nuts have a plain flange that distributes pressure evenly for a wide variety of fastening applications. They are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. Also known as collar nuts.
    Fiberglass
    Fiberglass—With the best strength-to-weight ratio of all our flange nuts, these hold up in high-stress applications without adding weight to your assembly. They also resist acids, solvents, oil, and salt water.

    These bellows withstand temperatures up to 500° F—more than twice as much as standard flat bellows. Use them to guard flat moving surfaces on machinery. Sewn seams let these bellows breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through.

    Image of Attribute. Front orientation. Contains Annotated. Bellows. High-Temperature Breathable Round Bellows with Flange Ends .
    These fiberglass bellows withstand temperatures up to 450° F—about twice as much as standard breathable round bellows with flange ends. They also protect against flames and sparks. Slide these bellows over moving parts such as rods and shafts. Sewn seams let them breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.
