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.

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.

A brass body provides protection against corrosive environments. Fittings have barbs that grip onto tubing.

Fittings with a single barb provide a smooth clamping surface for extra-tight connections that minimize leaks.

UN/UNF (SAE Straight) male threads with gasket provide extra protection against leaks. Also known as O-ring boss threads.

The nickel plating on these brass fittings provides extra protection against corrosive environments. The plating won’t peel or chip, so the fittings keep a bright, polished appearance. The barbs grip onto tubing, providing a secure hold with no clamp required.

UN/UNF (SAE Straight) and BSPP male threads have an O-ring to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Insert tubing into these fittings and an internal gripping ring and O-ring hold the tubing tight. They are also known as instant fittings. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance. Use them in low-pressure applications.

Identification rings (sold separately) snap over the release ring so you can color-code your lines.

Clips (sold separately) align and organize your tubing and fittings.

BSPP and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

With no latch, these couplings have a compact design to fit in small spaces. They connect with a push and disconnect with a pull, so you can easily access your line. Couplings consist of a plug and a socket (sold separately). They have a universal connection, so the plugs will connect to any of the sockets regardless of the pipe or tube size. They are nickel-plated brass for very good corrosion resistance.

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

Thread these fittings into motors, bearings, engine blocks, and other machinery to create a lubrication point. They’re also known as hydraulic grease fittings.

Zinc-plated steel fittings have mild corrosion resistance. UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.
