The BT0-5022 45° Female O-Ring x Air-O-Crimp Hose Fitting is engineered for mobile air conditioning systems that require a stepped hose transition combined with improved angular routing.
This fitting transitions from a #12 Air-O-Crimp clamp-style hose connection to a #10 female O-ring (FOR) sealing surface with 7/8-14 threads. The 45-degree angle reduces hose stress, improves clearance around components, and simplifies installation in tight engine bays or equipment compartments.
The female O-ring connection delivers a reliable and serviceable seal when paired with the proper O-ring. Meanwhile, the Air-O-Crimp clamp interface ensures a strong mechanical bond to #12 universal or nylon barrier hose when installed using approved clamp tools.
Constructed from durable steel, the BT0-5022 resists vibration, pressure cycling, and demanding operating conditions commonly found in:
-
Heavy-duty trucks
-
Agricultural equipment
-
Construction machinery
-
Off-road vehicles
-
Automotive A/C systems
This fitting is designed exclusively for Air-O-Crimp clamp-style hose assemblies and is not compatible with EZ-Clip systems.
When your application requires stepping down from #12 hose to a #10 O-ring port with a 45° angle for improved routing, the BT0-5022 provides a clean and professional-grade solution.
