About Female bulkhead connectors

Straight bulkhead push-in connectors take a line through a wall, a control panel or a machine cover and leave a push-in port on either side. They accept tube with an outside diameter of 3 to 16 mm, and reducing versions join two different sizes. Working pressure reaches 20 bar and vacuum down to -0.99 bar.

What matters when choosing

• Tube outside diameter: 3 to 16 mm, set separately for each side on the reducing types.
• Panel thread: M8x0.75 to M24x1.0 male, governed by the hole already in the sheet metal.
• Series: click-clock, Blue Series, Blue Series mini, metallica, NonPlusUltra and inox line differ in shape and material, from plastic through nickel plated brass to stainless steel 1.4404.
• Sealant: NBR for compressed air, FKM or FPM for oil and higher temperatures, and the FDA compliant FKM version near food production.
• Medium and temperature: besides compressed air the parts handle neutral gases, liquids, oil and grease, with operating temperature from -20 °C to 150 °C depending on series.

Typical applications

• Routing compressed air lines through cabinet and enclosure walls
• Connection panels on machine guarding
• Test rigs with defined ports on the front plate
• Vacuum handling with suction cups
• Air service units whose lines are taken out of the housing in an orderly way

Materials range from nickel plated brass through plastic to stainless steel 1.4404, and an FDA compliant FKM seal is available for work close to food. The group holds 60 articles drawn from six series.
