BT0-5119 90° Female O-Ring x Air-O-Crimp Hose Fitting – Long Port (No Nut) – #10H x #10F

The BT0-5119 90° Female O-Ring x Air-O-Crimp Hose Fitting – Long Port (No Nut) is engineered for mobile air conditioning systems that require extended port depth and custom mounting hardware.

This fitting features a #10 Air-O-Crimp clamp-style hose end and a #10 female O-ring connection (7/8-14 thread) arranged in a 90-degree configuration. The angled design improves hose routing and reduces stress in tight engine compartments and heavy-duty equipment installations.

The long-port (LGPT) design provides extended sealing engagement compared to standard port lengths. The No Nut (NN) configuration means the fitting is supplied without an integral retaining nut, allowing use with application-specific hardware or bulkhead-style mounting systems.

The female O-ring sealing surface provides dependable leak resistance when installed with the proper O-ring. The Air-O-Crimp clamp interface forms a secure mechanical bond to #10 universal or nylon barrier hose when installed using approved clamp tools.

Constructed from durable steel, the BT0-5119 withstands vibration, refrigerant pressure cycling, and demanding operating environments found in:

• Heavy-duty trucks

• Agricultural equipment

• Construction machinery

• Off-road vehicles

• Industrial mobile HVAC systems

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 90° connection between #10 hose and a #10 female O-ring port with extended port depth and no retaining nut, the BT0-5119 delivers a durable and professional-grade solution.
