The BT0-5090 Air-O-Crimp Weld-On Fitting – 1/2″ Tube x #8 Hose is engineered for mobile air conditioning systems requiring a permanent weld connection between rigid tubing and flexible barrier hose.
This fitting features a 1/2″ tube weld stub designed to be brazed or welded to hard line tubing, tanks, manifolds, or fabricated components. Once installed, the opposite end accepts a #8 Air-O-Crimp clamp-style hose assembly, allowing seamless integration into mobile HVAC systems.
Weld-on fittings are commonly used in:
-
Custom OEM fabrication
-
Refrigerant manifold builds
-
Hard line conversions
-
Receiver-drier modifications
-
Agricultural and heavy equipment retrofits
The Air-O-Crimp clamp interface ensures a secure mechanical bond to #8 universal or nylon barrier hose when installed using approved clamp tools.
Constructed from durable steel, the BT0-5090 withstands refrigerant pressure, vibration, and harsh operating environments found in:
-
Automotive A/C systems
-
Heavy-duty trucks
-
Agricultural equipment
-
Construction machinery
-
Industrial mobile HVAC systems
This fitting is designed exclusively for Air-O-Crimp clamp-style hose assemblies and is not compatible with EZ-Clip systems.
When fabricating or modifying A/C hard lines with 1/2″ tubing, the BT0-5090 provides a professional and permanent weld-on solution for #8 hose integration.
