Eaton 1873 Female Bulkhead Brass

The Eaton 1873 is a brass female bulkhead fitting built for 1/4 inch tube size connections in air brake systems. It serves bus fleets and heavy-duty vehicle maintenance where corrosion resistance and long service life are required.

Replaces worn brass bulkhead fittings

When an existing bulkhead shows thread damage, leakage or corrosion at the panel penetration, this fitting restores a secure push-connect joint. The upgrade is worth it when the original hardware can no longer hold pressure or pass inspection.

Installs into a panel cutout with standard tools

Thread the body through the bulkhead, tighten the locknut, and press the 1/4 inch tube into the push-connect end. The most common issue is cross-threading the locknut or failing to deburr the tube, either of which can cause leaks.

Questions about this item

What thread does the Eaton 1873 brass bulkhead fitting use for panel mounting?

The fitting uses a 1/4-18 thread for the bulkhead connection.

How do you install the Eaton 1873 brass bulkhead into a panel, and which step is often missed?

Insert the body through the panel hole, thread the locknut from the back, and tighten it securely; the step often missed is fully tightening the locknut to prevent vibration leaks.

When should the Eaton 1873 brass bulkhead be replaced in an air brake system?

Replace the fitting if the brass body shows cracks, the threads are damaged, or corrosion appears on the sealing surfaces during routine inspection.
