UV-Resistant Polypropylene Pipe Fittings for Chemicals
Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded 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.
Schedule 40 fittings have thinner walls than Schedule 80 fittings and are typically used in commercial and residential applications.
Schedule 80 fittings have thicker, stronger walls than Schedule 40 fittings for heavy duty, industrial chemical processing applications.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Connect the flanged end to another quick-clamp fitting with a clamp and a gasket (all sold separately). Fittings are polypropylene, which resists a wide variety of acids, solvents, and other harsh chemicals. The fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
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.

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings. Also known as luer lock couplings, they consist of a plug and socket (sold separately) that connect with a half turn. They have a compact body for easy installation in tight spaces. Plugs and sockets are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size.
Polypropylene plugs and sockets are moisture resistant and won’t absorb water and lose strength, even in high-humidity environments.
Note: For a complete coupling, order a plug and a socket.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect fittings with a release ring, push on the release ring and pull the tubing out of the fitting.
Polypropylene fittings have excellent impact and abrasion resistance. They meet NSF/ANSI standards for safe use with food. Some are also FDA compliant for indirect contact with food.
Black fittings have excellent UV resistance and are suitable for outdoor environments.

Plastic Cam-and-Groove Hose Couplings for Water

Made of polypropylene, these couplings are lighter in weight than metal cam-and-groove couplings and have good abrasion and corrosion resistance. 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.
Sockets with locking levers prevent accidental disconnection. The locking pins engage automatically when the coupling is connected. Press the locking pins simultaneously to disengage.
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.
