About Male bulkhead connectors

Straight push-in bulkhead fittings take a compressed air line through a panel or enclosure wall. The plastic tube pushes into the front and is released again at the collet, while a female thread on the back picks up the next component. The range joins tube outside diameters from 4 to 12 mm at a working pressure up to 10 bar.

What matters when choosing

• For tube O.D.: 4 to 12 mm. What counts is the outside dimension of the plastic tube or hose, not its bore.
• Thread: G 1/8, G 1/4, G 3/8 and G 1/2 female at the rear, chosen to suit the component connected behind the wall.
• Panel thread: M12x1 through to M22x1, matching the hole in the panel or enclosure. It grows with the tube size.
• Working pressure: -0.95 to 10 bar in continuous duty, with 15 bar quoted for short peaks. Size the system on the lower figure.
• Material: plastic or nickel plated brass with an NBR seal, released for compressed air.

Typical applications

• Feeding compressed air lines through control cabinet walls
• Connecting pneumatic valves behind a machine guard
• Operator panels where the line is plugged in from outside
• Jig and assembly work using plastic tubing and plastic pipe
• Separation points between plant modules that are opened for service

The Blue Series parts are made of plastic or nickel plated brass and seal with NBR, the intended medium being compressed air. Production is in China.
