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.

Nuts with Built-In Sleeve for Plastic Compression Tube Fittings for Water

- Temperature Range: -40° to 200° F
- Tubing: Use with hard (Durometer 0D-75D) nylon plastic or polypropylene plastic
Use these nuts with plastic compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut. Nuts are moisture-resistant acetal, so they won't absorb water and soften, even in high-humidity environments.

Nuts with Built-In Sleeve for Plastic Compression Tube Fittings for Air

- For Use With: Air, Lubricated Air
- Temperature Range: -30° to 210° F
- Tubing: Use with firm or hard nylon plastic, polyethylene plastic or polypropylene plastic
Use these nuts with plastic compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut. Nuts are polypropylene, which has excellent impact and abrasion resistance.

Crimp-On Ferrules for Air and Water Hose

Use ferrules to create a permanent connection between your air- and water-hose and barbed hose fittings. You will need a hose crimper (sold separately) for installation.
Brass and aluminum ferrules have good corrosion resistance. Choose a ferrule with an ID no more than 0.025" larger than your hose OD (measured with the fitting installed); also make sure the ferrule is at least as long as the barbed end of your fitting.
304 stainless steel ferrules offer very good corrosion resistance. Choose a ferrule with an ID no more than 0.031" larger than the hose OD (measured with the fitting installed).

Crimp-On Ferrules for Welding Hose

Use ferrules to create a permanent connection between your welding hose and barbed hose fittings. You will need a hose crimper (sold separately) for installation. Ferrules are brass for good corrosion resistance.

Screw-On Hose Fittings for Air and Water

The female connector screws directly onto rubber hose without the need for a separate adapter. You’ll need a female connector (ferrule) and a male adapter (stem) with the same hose ID to make a connection. Screw the female connector onto hose, then thread the male adapter into the female connector. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.
303 stainless steel fittings have better corrosion resistance than brass fittings.
