70R4301S Straight Male O-Ring Refrigerant Steel Fitting – #10 Hose × #10

The 70R4301S straight male O-ring refrigerant fitting provides a secure and leak-resistant connection for #10 refrigerant hose assemblies. It is commonly used in mobile air conditioning systems where durability and sealing strength matter.

Because this fitting is made from steel, it holds up well to vibration, pressure changes, and daily use. Additionally, the straight design allows for clean hose routing when space is limited. As a result, installation stays simple and service-friendly.

Furthermore, the 7/8-18 male O-ring thread helps create a tight seal when paired with the correct O-ring. Therefore, this fitting is a dependable choice for repair and replacement work in demanding environments.

NOTE: For all refrigerant fittings, be sure to use refrigerant hose or equivalent.
