    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.

    High-Temperature PTFE Pipe Fittings for Harsh Chemicals

    Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They have the chemical resistance to stand up to acid and solvents. Fittings have thick, Schedule 80 walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so these fittings are commonly used in high-purity processes, such as semiconductor and clean room applications. They have a super-smooth interior for unrestricted flow.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    Thread Sealant

    Applicator-Top Can

    To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns. Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

    Right-Angle Flow Rectangular Manifolds

    Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers. They have mounting holes, so you can mount from the top or side.

    PTFE manifolds have the best chemical and corrosion resistance of all the plastic and metal manifolds we offer, so they’re the best choice for acids and other highly corrosive substances. Do not use with deionized water at temperatures above 120° F.
