High-Purity PVDF Pipe Fittings for Corrosive Chemicals
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.

Flame-Retardant PVDF Pipe Flanges for Chemicals
- For Use With: Chlorine, Salt Water, Solvents
- Temperature Range: 40° to 280° F
- Specifications Met: ASTM D3222, UL 94 V-0
- Pipe Nipples and Pipe: Use Schedule 80 PVDF Plastic
- Fittings: Use Schedule 80 PVDF Plastic
Flanges meet UL 94 V-0 for flame retardance to delay the spread of flames to valuable equipment. They are made of PVDF (polyvinylidene fluoride), which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances. Also known as Pressure Class 150 flanges, they have thick, strong walls for heavy duty chemical processing applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. When connecting to pipe, 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 flange, then wrench-tighten one to two turns. Flanges meet ASTM D3222 specifications and testing requirements for material quality.
Warning: Never use plastic pipe flanges 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.

Plastic Pipe Fittings for Oil
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.

Chemical-Resistant PVDF Pipe Fittings for Food and Beverage
- For Use With: Beverage, Chlorine, Deionized Water, Food, Hydrochloric Acid, Phosphoric Acid
- Temperature Range: 0° to 240° F
- Specifications Met: FDA Compliant 21 CFR 177.2510, IEC 60695-11-10, NSF/ANSI 61
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 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.

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.

Plastic Cam-and-Groove Hose Couplings for Chemicals and Petroleum
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.

Quick-Disconnect Plastic-Shape Hose Couplings for Food and Beverage
Couplings are suitable for food and beverage applications and won’t impart tastes or odors to the product. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. All of the quick-disconnect food and beverage plugs are compatible with any of the quick-disconnect food and beverage sockets of the same coupling size, regardless of the pipe size. They are PVDF, which has excellent abrasion and corrosion resistance and withstands the damaging effects of UV light.
Plugs are also known as nipples.
Sockets have a shut-off valve that stops the flow when the coupling is separated, so product won’t leak from the line. They are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket back until the plug ejects.
