Chemical-Resistant PVDF Hose Fittings for Food and Beverage
- Maximum Pressure: 205 psi @ 72° F
- Temperature Range: 0° to 245° F
- Attachment Type: Use Worm-Drive Clamps or Bolt Clamps
- Specifications Met: NSF/ANSI 61, UL 94 V-0
To stand up to the harsh chemicals used to clean food-processing lines, these fittings are made of PVDF (polyvinylidene fluoride), also known as Kynar. They’ll resist degrading when exposed to strong alkali and highly acidic solutions, unlike other plastic fittings, such as those made from nylon and acetal. They are NSF/ANSI 61 certified for use in drinking water systems, and they won't impart any tastes or odors. Use them with both hot and cold substances. Since they're made of PVDF, these fittings can stand up to impact. Rated UL 94 V-0, they meet strict flammability standards.
Warning: Never use plastic hose fittings and pipe with compressed air or gas.

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.

High-Temperature PTFE Pipe Fittings for Chemicals
Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They have the chemical resistance to stand up to acid and solvents. Fittings have thick, Schedule 80 walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so these fittings are commonly used in high-purity processes, such as semiconductor and clean room applications. They have a super-smooth interior for unrestricted flow. 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 D1710 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.
