Thick-Wall Plastic Pipe Fittings for Water
Connect these fittings to Schedule 80 pipe–they have thicker, stronger walls than standard-wall fittings so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Fittings are plastic for good corrosion resistance. They meet ASTM specifications and testing requirements for material quality.
Fittings for drinking water meet NSF/ANSI Standard 61.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Metal Cam-and-Groove Hose Couplings for Water
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.
Plugs with male threaded end are also known as F adapters.
Plugs with female threaded end are also known as A adapters.
Aluminum couplings are lighter in weight than brass plugs and sockets. They have good abrasion and corrosion resistance. Brass couplings are softer than aluminum plugs and sockets, so they’re easier to thread together. 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.

Metal Cam-and-Groove Hose Couplings for Chemicals and Petroleum
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 male threaded end are also known as F adapters.
Plugs with female threaded end are also known as A adapters.
Aluminum plugs and sockets are lighter in weight than 316 stainless steel plugs and sockets. They have good corrosion resistance. 316 stainless steel plugs and sockets have excellent 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.

Air-Inflatable Plugs
Conform to wide and out-of-round pipes with these inflatable plugs. Also known as pneumatic plugs, they're designed for temporary seals since they can lose pressure over time. Inflate with a hand pump (sold separately); an air compressor may overinflate the plug and cause damage. Tether the plugs using either the eyebolt or chain/ring so they don't get lost or stuck in your pipes. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.
