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.
Metric, BSPP, and UN/UNF (SAE Straight) male threads have a gasket or O-ring for a tight seal. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Screw-On Nut Barbed Tube Fittings for Air
- Temperature Range: 20° to 140° F
- Tubing: Use with firm or hard (Durometer 95A-60D) 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.
Metric and BSPP male threads with gasket provide extra protection against leaks.

Through-Wall Straight Connectors, Tube
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.
Quick-Clamp High-Vacuum Fittings for Stainless Steel Tubing
- For Use With:
Fittings with Gasket End: Air, Argon, Helium, Nitrogen
All Other Fittings: Air - Temperature Range: 0° to 300° F
- Tubing: Use with 304/304L or 316/316L stainless steel
- Specifications Met: ISO 2861
Instead of a gasket, these fittings have a special ring that is designed for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases. Also known as KF, QF, and NW fittings, they are the most common type of connection in high-vacuum systems. Connect with a clamp and another quick-clamp fitting for fast, easy access to your line. To use fittings in pressure applications, use a pressure-rated ring (sold separately).
Aluminum fittings have good corrosion resistance and are lighter than stainless steel fittings. Note: To complete a connection, you’ll need two quick-clamp fittings, a ring, and a clamp (all sold separately).
