Industrial Nickel-Plated Brass Fitting

This B-Series all-metal fitting is intended for applications where plastic-bodied fittings may not be preferred. Nickel-plated brass provides excellent mechanical strength, corrosion resistance and long service life in demanding pneumatic and vacuum installations.

Typical Applications

  • Routing compressed air through an enclosure wall
  • Providing vacuum-line access at an equipment panel
  • Creating a serviceable connection between inside and outside tubing
  • Improving organization of OEM machine panels

Fitting Function

A bulkhead connector provides a defined pneumatic or vacuum tube connection through a machine panel or enclosure, with access for maintenance on both sides.

Installation Note: Cut tubing squarely and push the tube fully into the fitting before pressurizing or applying vacuum. To remove tubing, depress the grip collar; the Click-Click release feedback helps confirm the collar has been disengaged for tube removal. Always confirm tubing compatibility for pressure, temperature and media.

Selecting and Installing This Fitting

For BM12, match the specified 12 mm tubing outside diameter at every connection. Do not rely on approximate inch/metric equivalence without checking tubing tolerances. Cut the tubing squarely, insert it fully and leave access to the release collar. Check actual tubing pressure and temperature limits, which may be lower than the metal fitting limits.

Frequently Asked Questions

What is a pneumatic bulkhead fitting used for?

It carries a tube connection through a panel or machine enclosure to create an accessible, supported connection between inside and outside tubing runs.

What tubing size fits this bulkhead?

BM12 uses 12 mm outside-diameter tubing. Check the model and tubing specification for both sides of the panel.

How is a bulkhead fitting secured?

Mount it through a suitable panel opening using its intended mounting hardware and leave clearance for the tube-release collars and any required service access.

When is a bulkhead preferable to passing tubing through a hole?

A bulkhead gives a defined connection point at the panel, simplifying service and reducing reliance on a long uninterrupted tube passing through the enclosure wall.

Is this fitting suitable for compressed air and vacuum?

The published all-metal B-Series range is specified for compressed air and vacuum service, subject to compatible tubing, proper sealing and the limits of the assembled system. Other fluids need separate compatibility confirmation.

What are the pressure and temperature limits?

The published fitting-family limits extend from full vacuum to 176 psi (12 bar, as listed for the fitting family), with a fitting temperature range of -40 to +248 °F (-40 to +120 °C). Actual system limits also depend on tubing, seals and installation; do not treat these as fluid-compatibility certifications.
