    Drain, Waste, and Vent Iron and Steel Pipe Fittings

    Use these fittings in gravity-flow applications both above and below ground. They are also known as no-hub pipe fittings and soil pipe fittings. To connect, place the end of the fitting against your pipe or another fitting and connect with a low-pressure clamp-on connector (sold separately). The clamp-on connector is also known as a no-hub coupling. Fittings are for use in noncorrosive environments.

    High-Pressure Aluminum Butt-Weld Pipe Fittings

    Thick walls give these Schedule 80 fittings excellent strength. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are aluminum, which is lightweight with good corrosion resistance.

    Low-Pressure Aluminum Socket-Connect Pipe Fittings

    Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings are aluminum, which is lightweight with good corrosion resistance.

    Low-Pressure Aluminum Quick-Connect Pipe Fittings

    Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system. Also known as Unipipe fittings, they’re part of a quick-connect system that’s compatible with pipe from Unipipe, Transair, and Infinity.
    Finger tighten the collar on the end of these fittings, then use a wrench for the final quarter turn. The inside of these fittings has a compression ring and O-ring to seal against the pipe. They’re easy to take apart as needed to modify your setup.
    Straight Reducing Adapters
    Quick Connect Fitting Connection—Use these adapters with a connector (sold separately) to change the line's size. The male end of these adapters should match the size of the connector. The female end of these adapters will reduce the size of the line. To install, remove and discard the connector's nut, grip ring, and collar. Thread the male end of the adapter into the female end of the connector.
    Threaded Fitting Connection—These adapters have pipe threads on one end to connect to your compressor or other component. Threaded connections can be taken apart as needed for maintenance and repair.
    Blue Collar—Fittings with a blue collar are often used for compressed air systems.
    Gray Collar—Fittings with a gray collar are often used for vacuum systems.

    Low-Pressure Aluminum Threaded Pipe Flanges

    Also known as Pressure Class 125 flanges, these are for use in low-pressure applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges are aluminum, which is lightweight with good corrosion resistance.
