Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Quick-Clamp Fittings for Dairy

- Temperature Range: See table
- Tubing: Use with soft (Durometer 50A-65A) silicone rubber
- Specifications Met: See table
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.
Note: For a complete connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

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.

Caps fit over a tube stem end of a fitting or a piece 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.

Plastic Quick-Clamp Sanitary Fittings for Stainless Steel Tubing

- For Use With: Dairy, Water
- Temperature Range: -40° to 170° F, except gaskets (see table)
- Tubing: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM A270
- Specifications Met: 3-A Certified 62-02, FDA Compliant 21 CFR 177.2510
Made of PVDF (Kynar), these fittings are lightweight compared to metal quick-clamp fittings. The clamp separates into three pieces and threads over the quick-clamp ends of the fittings to create an access point in a line. Tighten the clamp with a spanner wrench (sold separately) for a secure seal.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

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.

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.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

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 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.
Plugs with male threaded end are also known as F adapters.
Plugs with female threaded end are also known as A adapters.
Plugs with barbed end are also known as E adapters. Insert the barbed end into rubber hose and secure with a clamp.
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.
