Made of PVDF that’s finished to a 12 Ra smoothness, these fittings handle some of the harshest chemicals without leaching contaminants into your line. They won’t accumulate particles and are easy to clean, thanks to their smoothness. Comparable to Kynar, these fittings handle most organic solvents that would dissolve CPVC, and chlorine or nitric acid that would weaken polypropylene. You can use them at higher temperatures than CPVC and polypropylene. These fittings meet UL 94 V-0 and FM standards for flame retardance. They’re also FDA compliant for direct contact with food, and they meet ASTM requirements for dimensions and tolerances.

Connect them to pipe with socket fusion welding for a strong, permanent bond. Use a socket fusion tool with a heater bushing (sold separately) that matches your pipe size.

Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies. All meet UL and ASTM standards for flame retardance and self-extinguishment in the case of fire. They also meet strict ASTM specifications and testing requirements for material quality and product dimensions. They’re compatible with Orion Blueline No-Hub and Orion Rionfuse chemical waste pipe and pipe fittings.

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.

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 sleeve (ferrule) compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. Fittings that include a gripper sleeve on the tubing create an even tighter seal.

PFA fittings stand up to harsh substances. They’re made through a melting process.

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.
