Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They also have high strength and impact resistance. 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.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Made of PVDF, also known as Kynar, these fittings stand up to the harsh chemicals used to clean food processing lines. Unlike other plastic fittings, such as nylon and acetal fittings, they’ll resist degrading when exposed to strong alkali and highly acidic solutions. These fittings are FDA compliant and meet NSF/ANSI 61, so they're safe to make direct contact with food and drinking water. They also won't transfer tastes or odors to your food and beverages. Use them with both hot and cold substances. Since they're made of PVDF, these fittings can stand up to impact. They meet strict IEC standards for flame retardance, so they delay the spread of flames.

Since these fittings are threaded, you can take apart their connections for maintenance and repair. When connecting to another fitting, 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.

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 PVDF (Kynar), these fittings are lightweight compared to metal quick-clamp fittings. The clamp separates into three pieces and threads over the quick-clamp ends of the fittings to create an access point in a line. Tighten the clamp with a spanner wrench (sold separately) for a secure seal.

Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once. They keep tubes organized and optimize space in tight spots. Often used in robotics, these couplings are ideal for complex pneumatic systems.

Through-wall couplings allow you to connect and disconnect air lines on a panel or machine. This is useful when you are going to transport and reconnect your equipment on site.

Barbed-connect fittings are for soft tubing.

Keyed couplings prevent mixing and matching the wrong lines, since they’ll only connect with a plug or socket that is keyed the same.

For a complete coupling, order a plug and a socket with the same coupling size.

Also known as single-use fittings, these are disposable so you don't have to sterilize your line. Join the flanged end of the fittings to any other sanitary stainless steel quick-clamp fitting (sold separately) with a gasket and a clamp for a fast and easy way to access your line. Fittings have a smooth interior to prevent product buildup and contamination. They are PVDF (also known as Kynar), which has excellent strength.

Note: For a complete connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. Use these fittings in low-pressure applications.

PVDF fittings offer excellent chemical resistance, and can be used with hydrochloric acid and nitric acid. They withstand temperatures up to 270° F, higher than other push-to-connect fittings for chemicals. They are produced in a clean room and are bagged individually to prevent dirt and moisture from contaminating the inside. PVDF is also known as Kynar.

A staple in labs, these couplings are highly versatile, fitting any luer lock plug, socket, syringe, or needle. They lock together with a push and turn, so they work well in lines that are frequently disconnected. Use them in low-pressure applications. They have a compact body for installation in tight spaces. Made of PVDF, they resist most acids, alcohols, and organic solvents. PVDF is also known as Kynar.

Note: For a complete coupling, order a plug and a socket.

A spring-free flow path allows more chemicals to pass through these tube couplings at lower line pressures than other quick-disconnect couplings. This reduces turbulence, foaming, bubbles, and blockage. They have a shut-off valve that stops the flow when the coupling is disconnected, so chemicals won’t leak from your line. Unlike couplings with a button release, these have a safety slide to reduce accidental separation from bumps or drops. They are often used in laboratories, pharmaceutical facilities, and other sterile environments.

Made of PVDF, also known as Kynar, these couplings have excellent chemical and UV resistance at ambient and elevated temperatures. They also resist abrasion, impact, flames, and corrosion. Compared to other quick-disconnect couplings for chemicals, these couplings can withstand higher temperatures—all the way up to 250° F.

When you insert the plug into the socket, it’ll connect with a click. To disconnect, slide the latch on the socket and remove the plug.

Note: For a complete coupling, order a plug and a socket with the same coupling size.

Made of plastic, these couplings are lighter in weight than metal cam-and-groove hose couplings, yet have the chemical resistance to withstand gasoline and other harsh substances. 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.

PVDF plugs and sockets have better corrosion and chemical resistance than nylon plugs and sockets. Use them when your application involves harsh acids and solvents.

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.
