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.

High-Flow Quick-Disconnect Tube Couplings for Chemicals
- For Use With: Acetic Acid (20%), Ammonia, Carbon Dioxide, Citric Acid, Diesel Fuel, Ethanol, Ethylene Glycol, Gasoline, Hydraulic Fluid (Petroleum Based), Hydrochloric Acid, Hydrogen Peroxide (30%), Kerosene, Methanol, Nitric Acid (20%), Potassium Hydroxide, Sodium Carbonate, Sodium Hydroxide (20%), Sulfuric Acid (75%), Synthetic Oil
- Temperature Range: 32° to 250° F
- Tubing: Use with soft or firm (Durometer 55A-95A) nylon plastic, polyethylene plastic, polypropylene plastic, polyurethane rubber, PVC plastic or TPE plastic
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.
They have a single barb that grips onto tubing or hose and provides a smooth clamping surface for extra-tight connections that minimize leaks.

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.
Fittings with tube stem insert into the push-to-connect end of another fitting in place of a length of tubing.

Luer Lock Tube Couplings for Plastic and Rubber Tubing—Chemicals
- For Use With: Acetic Acid, Bleach, Ethanol, Hydrochloric Acid, Nitric Acid, Phosphoric Acid, Sulfuric Acid
- Tubing: Use with soft (Durometer 40A-65A) PVC plastic or silicone rubber
A staple in labs, these couplings are highly versatile, fitting any luer lock plug, socket, syringe, or needle. They lock together with a push and turn, so they work well in lines that are frequently disconnected. Use them in low-pressure applications. They have a compact body for installation in tight spaces. Made of PVDF, they resist most acids, alcohols, and organic solvents. PVDF is also known as Kynar.
Note: For a complete coupling, order a plug and a socket.

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.
