Flame-Retardant PVDF Pipe Fittings 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
- Flanges: Use Class 150 PVDF Plastic
These fittings meet UL 94 V-0 for flame retardance, so they 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 Schedule 80 fittings, they have thick walls for heavy duty chemical processing applications. 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 fitting, then wrench-tighten one to two turns. Fittings meet ASTM D3222 specifications and testing requirements for material quality.
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.

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.

Plastic Push-to-Connect Tube Fittings for Chemicals
- For Use With: Inch: Alcohol, Hydrochloric Acid, Nitric Acid, Sodium Carbonate, Sulfuric Acid
Metric: Acetic Acid, Alcohol, Arsenic Acid, Benzoic Acid, Fluoboric Acid, Sodium Carbonate, Sulfuric Acid - Temperature Range: Inch: 0° to 270° F
Metric: 32° to 175° F - Tubing: Use with hard (Durometer 55D-60D) FEP plastic
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.
