Brass Low-Pressure Barbed Tube Fittings for Air and Water
A brass body provides protection against corrosive environments. Fittings have barbs that grip onto tubing.
NPTF (Dryseal) fittings are compatible with NPT threads.
- Temperature Range: -65° to 75° F
- Tubing: Use with firm (Durometer 95A) polyurethane rubber

Nickel-Plated Brass Low-Pressure Barbed Tube Fittings for Air and Water
The nickel plating on these brass fittings provides extra protection against corrosive environments. The plating won’t peel or chip, so the fittings keep a bright, polished appearance. The barbs grip onto tubing, providing a secure hold with no clamp required.
UN/UNF (SAE Straight) and BSPP male threads have an O-ring to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.
- Temperature Range: -20° to 160° F
- Tubing: Use with firm (Durometer 85A) polyurethane rubber
Fittings with intermittent swivel rotate 360° before and after installation as needed to allow movement in the system and to prevent kinking.
- Temperature Range: -40° to 230° F
- Tubing: Use with hard (Durometer 60D-90D) Buna-N rubber, EVA plastic, Nylon plastic, polyethylene plastic, polypropylene plastic, polyurethane rubber, PTFE plastic, PVC plastic, PVDF plastic, or silicone rubber
Aluminum Low-Pressure Barbed Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water
- Temperature Range: -40° to 230° F
- Tubing: Use with hard (Durometer 75A-60D) EVA plastic, polyethylene plastic, polyurethane rubber or PVDF plastic
Made of aluminum, these fittings are lighter in weight than other metal barbed tube fittings and have good corrosion resistance. The barb grips onto tubing, providing a secure hold with no clamp required.

Stainless Steel High-Pressure Barbed Tube Fittings for Air and Water
- Temperature Range: See table
- Tubing: Use with firm (Durometer 75A-95A) EVA plastic, polyethylene plastic, polypropylene plastic or PVC plastic
Fittings withstand pressures up to 250 psi. They are 303 stainless steel for very good corrosion resistance.
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.
Bronze fittings have better corrosion resistance and are stronger than brass and aluminum fittings. A pipe thread sealant is recommended to seal bronze fittings with BSPP male threads, which is unlike other materials that can often use a gasket.
Fittings with a threaded end are also known as hose nipples.
- Maximum Pressure: 100 psi @ 72° F
- Temperature Range: -32° to 212° F
- Attachment Type: Use Worm-Drive Clamps
- Specifications Met: ASTM B584
Push-On Barbed Hose Fittings for Hydraulic Fluid
These fittings have sharp barbs to grip rubber push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use them in low-pressure hydraulic applications up to 350 psi. Also known as hose nipples, they adapt a barbed end to a threaded end, so you can connect to pumps, cylinders, and other equipment in your hydraulic system. Fittings are zinc-plated steel, which has excellent strength and durability. Fittings have fair corrosion resistance.
Fittings that swivel until tightened rotate 360° for easy installation.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.
- Maximum Pressure: See table
- Maximum Vacuum: 28 in. of Hg @ 72° F
- Temperature Range: -40° to 255° F
