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.

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.
| For Tube ID | Material | Max. Pressure | For Hole Dia. | For Max. Wall Thick. | Each | |
| 1/16" | Aluminum | 125 psi @ 72° F | 3/16" | 1/4" | 00000000 | 000000 |
| 1/8" | Aluminum | 125 psi @ 72° F | 1/4" | 5/16" | 00000000 | 00000 |
| 0.17" | Aluminum | 125 psi @ 72° F | 5/16" | 13/32" | 00000000 | 00000 |
| 1/4" | Aluminum | 125 psi @ 72° F | 3/8" | 13/32" | 00000000 | 00000 |
| 3/8" | Aluminum | 125 psi @ 72° F | 1/2" | 13/32" | 00000000 | 00000 |
| 1/2" | Aluminum | 125 psi @ 72° F | 3/4" | 53/64" | 00000000 | 00000 |
Screw-On Nut Barbed Tube Fittings for Air
- Temperature Range: 20° to 140° F
- Tubing: Fittings with Anodized Aluminum, Brass, or Nylon Plastic Material: Use with firm or hard (Durometer 95A-60D) polyethylene plastic or polyurethane rubber
Fittings with 316 Stainless Steel Material: Use with firm or hard (Durometer 80A-95A) nylon plastic, polyethylene plastic or polyurethane rubber
You don’t need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.
Aluminum and nylon fittings have better corrosion resistance than brass and are lighter in weight.
