The 70R9301S straight male O-ring fitting is engineered for mobile air conditioning applications that require a direct #10 male O-ring connection to a #10 refrigerant hose. Its steel construction offers excellent strength and vibration resistance, while the reduced beadlock design supports reliable hose retention with a slimmer overall profile.
This fitting is well suited for heavy-duty truck and industrial HVAC applications where durability, space efficiency, and long-term sealing performance are critical. Broad OEM and aftermarket cross references make it a dependable option for service repairs and custom hose assemblies.
