Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Also known as 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.
Reducing flanges allow you to transition your system to a smaller pipe size.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications. To prevent cracking, do not tighten more than a 1/4-turn past hand tight.
Adapters for tanks weld onto the surface of any tank, pressure vessel, or drum to create a permanent inlet or outlet connection. Adapters with extended lip fit tightly into the hole, which keeps the fitting steady during welding.
NPTF (Dryseal) threads and NPSL (National Pipe Straight Locknut) threads are compatible with NPT threads.

Also known as 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.
Butt-weld flanges are also known as weld-neck flanges; the flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld. Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides. Reducing flanges let you transition your system to a smaller pipe size. Cap flanges are also known as blind flanges.

Made of metal, these couplings have better durability than plastic cam-and-groove couplings. A complete coupling consists of a plug and a socket (both sold separately) that allow you to quickly connect and disconnect medium-to large-diameter hose lines. To connect, insert the plug into the socket and press the levers down. The levers fit snugly into the groove on the plug’s body and force the plug against the gasket to form a tight seal. To disconnect, lift both levers and pull out the plug. Couplings are compatible with Andrews, Dixon, Ever-Tite, and PT cam-and-groove couplings.
Plugs with flanged end are also known as PFA adapters. Bolt the flanged end to another same-size flange with a gasket (sold separately).
Sockets with flanged end are also known as PFC couplers. Bolt the flanged end to another same-size flange with a gasket (sold separately).
Aluminum plugs and sockets are lighter in weight than 316 stainless steel plugs and sockets. They have good corrosion resistance.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.
