How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Tight-Seal Plastic Barbed Tube Fittings for Air and Water
Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections. Fittings are nylon for excellent impact and abrasion resistance.

Stainless Steel Barbed Tube Fittings for Food and Beverage
- Temperature Range: -20° to 750° F
- Tubing: Use with soft or firm (Durometer 65A-90A) polyurethane rubber or PVC plastic
- Specifications Met: See table
Made of stainless steel, these fittings are more durable than plastic barbed tube fittings for food and beverage. They have single or multiple barbs that grip onto tubing.

High-Pressure Barbed Plastic Pipe Fittings for Water
Use these barbed pipe fittings in industrial plumbing, water processing, and water supply applications up to 200 psi. They meet NSF/ANSI Standard 61 for drinking water. Also known as insert fittings, they have a barbed end that slides into semi-flexible plastic pipe and secures with a clamp (sold separately). Since you don't have to wait for cement to dry, they're quicker to install than socket-connect fittings. Fittings are PVC, which has good strength and corrosion resistance. They meet ASTM D1784 specifications and testing requirements for material quality and ASTM D2609 specifications for barb dimensions.
Note: Barbed pipe fittings are measured by pipe size, which is not an actual measured size, but rather an industry designation.
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.
