    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

    Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges meet ASTM D4024 specifications and testing requirements for product dimensions, performance, and material quality.
    To connect flanges to pipe, first sand the inside of the flange and the end of the pipe to remove the surface finish. Next, mix the adhesive (sold separately) until the color is uniform with no streaks. Apply a thin layer of mixed adhesive to the sanded area of the pipe, approximately 1/8" thick. Repeat this process with the inside of the flange, applying a layer approximately 1/16" thick. After sealant has been applied, push the flange onto the pipe until it is fully engaged. Make sure you align the bolt holes prior to installing to minimize rotation after the flange is installed. Finally, use the adhesive-curing heat cable (sold separately) to cure the adhesive. Wrap the tape around the pipe and flange at the joint, taking care to not overlap the tape. Once you have waited the full cure time, the pipe and flange will be ready to use.

    Ultra-Chemical-Resistant High-Strength PTFE Pipe Gaskets with Bolt Holes

    Image of ProductInUse. Front orientation. Pipe Gaskets. Ultra-Chemical-Resistant High-Strength PTFE Pipe Gaskets with Bolt Holes.
    A fiberglass filler in these PTFE gaskets provides strength to prevent them from thinning out when compressed. They resist hydrocarbons, solvents, refrigerants, and moderate concentrations of acids. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. All gasket specifications are sized to meet ANSI standards.
    Plain-Back Gaskets for ANSI Flanges
    For ANSI Class 150—Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges.
    For ANSI Class 300—Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

    Ultra-Chemical-Resistant High-Strength PTFE Pipe Gaskets

    Image of ProductInUse. Front orientation. Pipe Gaskets. Ultra-Chemical-Resistant High-Strength PTFE Pipe Gaskets.
    Reinforced with fiberglass filler for strength, these PTFE gaskets won’t thin out when compressed. They resist hydrocarbons, solvents, refrigerants, and moderate concentrations of acids. Also known as ring gaskets, use them with raised-surface pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. All gaskets are compatible with low-pressure pipe flanges and are sized to meet ANSI standards.
