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.

Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through your wall or panel to create an inlet or outlet.

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.
For technical drawings and 3-D models, click on a part number.
- Temperature Range: -65° to 75° F
- Tubing: Use with firm (Durometer 95A) polyurethane rubber
Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through your wall or panel to create an inlet or outlet.
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.
NPSM (National Pipe Straight Mechanical) male threads are compatible with NPSM and NPSH threads.
For technical drawings and 3-D models, click on a part number.
- Temperature Range: -50° to 275° F
- Tubing: Use with firm (Durometer 75A-80A) polyurethane rubber or PVC plastic
- Clarity: Black: Opaque; White: Semi-Clear
Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through your wall or panel to create an inlet or outlet.
