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.

- Temperature Range:
Inch: -40° to 270° F
Metric: 0° to 240° F - Tubing: Use with firm or hard (Durometer 45D-65D) nylon plastic, polyethylene plastic, or polypropylene plastic
- Specifications Met:
Inch: FDA Compliant 21 CFR 177.2510, NSF/ANSI 51, NSF/ANSI 61, USP Class VI
Metric: FDA Compliant 21 CFR 177.2510, NSF/ANSI 61
Made of PVDF (also known as Kynar), these fittings have excellent strength and can handle temperatures as high as 240° F or 270° F. All fittings meet NSF/ANSI 61 and are safe to use for drinking water systems. They’re also known as flareless fittings.
Assemble fittings with a plastic sleeve without removing their nut. This built-in sleeve—commonly called a ferrule—compresses the tubing as you tighten the nut, creating a strong seal.

- For Use With: Inch: Acetic Acid, Alcohol, Arsenic Acid, Benzoic Acid, Fluoboric Acid, 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, and an internal gripping ring and fluoroelastomer O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting.
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.
NPTF (Dryseal) threads are compatible with NPT threads.

- For Use With: Beverage, Food
- Temperature Range: -80° to 220° F
- Tubing: Use with soft or firm (Durometer 50A-80A) plastic blend, polyethylene plastic, polyurethane rubber, PVC plastic, or silicone rubber
- Specifications Met: FDA Compliant 21 CFR 177.2510, FDA Compliant 21 CFR 177.1520
Fittings have a single barb that creates a smooth clamping surface for extra-tight connections that minimize leaks. Designed for high-purity applications, they are produced in a clean room and are double bagged to prevent dirt and moisture from contaminating the inside. Fittings are PVDF (also known as Kynar), which has excellent strength.
