BT0-5109 Straight Bulkhead Female O-Ring x Air-O-Crimp Hose Fitting – #6H x #6F

The BT0-5109 Straight Bulkhead Female O-Ring x Air-O-Crimp Hose Fitting is engineered for mobile air conditioning systems requiring a secure pass-through connection between compartments.

This fitting features a #6 Air-O-Crimp clamp-style hose end and a #6 female O-ring port (5/8-18 thread) in a straight configuration. The bulkhead design allows the fitting to be mounted through a firewall, panel, or bracket using retaining hardware, creating a stable and vibration-resistant installation point.

The straight orientation is ideal where space allows direct hose routing through cab walls, equipment housings, or fabricated panels.

Bulkhead fittings are commonly used in:

• Cab-to-engine refrigerant routing

• OEM panel-mounted installations

• Firewall pass-through applications

• Custom fabrication projects

The female O-ring sealing surface provides dependable leak resistance when installed with the correct O-ring. The Air-O-Crimp clamp interface forms a secure mechanical bond to #6 universal or nylon barrier hose when installed using approved clamp tools.

Constructed from durable steel, the BT0-5109 withstands refrigerant pressure, vibration, and demanding operating conditions found in:

• Automotive A/C systems

• Heavy-duty trucks

• Agricultural equipment

• Construction machinery

• Off-road vehicles

This fitting is intended exclusively for Air-O-Crimp clamp-style hose assemblies and is not compatible with EZ-Clip systems.

When your application requires a straight bulkhead-mounted connection between #6 hose and a #6 female O-ring port, the BT0-5109 provides a durable and professional-grade solution.
