    Extreme-Pressure Iron and Steel Threaded Pipe Fittings

    The strongest steel fittings we offer, these can withstand extreme-pressure applications.
    Note: The maximum pressure listed for Class 6000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

    Flame-Retardant High-Purity PVDF Pipe Fittings for Harsh Chemicals

    Made of PVDF that’s finished to a 12 Ra smoothness, these fittings handle some of the harshest chemicals without leaching contaminants into your line. They won’t accumulate particles and are easy to clean, thanks to their smoothness. Comparable to Kynar, these fittings handle most organic solvents that would dissolve CPVC, and chlorine or nitric acid that would weaken polypropylene. You can use them at higher temperatures than CPVC and polypropylene. These fittings meet UL 94 V-0 and FM standards for flame retardance. They’re also FDA compliant for direct contact with food, and they meet ASTM requirements for dimensions and tolerances.
    Connect them to pipe with socket fusion welding for a strong, permanent bond. Use a socket fusion tool with a heater bushing (sold separately) that matches your pipe size. 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.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    Stub-End Straight Adapters
    Image of Product. Front orientation. Pipe Stub Ends. Flame-Retardant High-Purity PVDF Pipe Fittings for Harsh Chemicals.
    Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.
