About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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).

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 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

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

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).
