Metal Barbed Hose Fittings for Air and Water
Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. Plain brass fittings have good corrosion resistance. Nickel-plated brass fittings resist corrosion better than plain brass fittings.
Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance.
Stainless steel fittings have very good corrosion resistance. 303 stainless steel fittings won’t rust when exposed to water, making them good for areas that require frequent cleanings. Fittings with a threaded end are also known as hose nipples.
Metric, UN/UNF (SAE Straight), and BSPP male threads with gasket protect against leaks.

Static-Control Soft Plastic and Rubber Tubing for Air and Water
Protect sensitive equipment with this tubing—it is specially formulated to reduce the buildup of static electricity.
Silicone rubber tubing has carbon embedded into the walls to divert static quickly. It can handle a wider temperature range than PVC tubing, and is more flexible, so it bends easily around objects. It is opaque, so you can’t see what’s flowing through the line.
- Flexible
- Compatible with Barbed Tube Fittings
- Soft (Durometer 70A)
- Temperature Range: -70° to 450° F
Flame-Retardant Soft Rubber Tubing for Air and Water
- Flexible
- Compatible with Barbed Tube Fittings
- Soft (Durometer 60A)
- Temperature Range: -70° to 450° F
This self-extinguishing, silicone rubber tubing meets UL 94 V-0 and UL 94 V-1 for flame retardance, so it delays the spread of flames to valuable equipment. It is opaque, so you cannot see what’s flowing through the line. Tubing is flexible to easily bend around objects.
Plastic Barbed Tube Fittings for Air and Water
Fittings have barbs that grip onto tubing.
Acetal fittings won’t absorb water and lose strength, even in high-humidity environments.
- Temperature Range: Nylon: 32° to 140° F
Acetal: -40° to 175° F - Tubing: Nylon: Use with firm or soft (Durometer 45A-80A) polyurethane rubber or PVC plastic
