The 70R9072S straight splicer fitting is engineered for mobile air conditioning applications that require joining two #12 refrigerant hoses while maintaining system serviceability. Its steel construction delivers excellent strength and vibration resistance, while the reduced beadlock hose ends support secure crimping with a slimmer overall profile.
An integrated 13mm R134a charge port allows for convenient charging and diagnostics without additional adapters. This fitting is well suited for heavy-duty truck and industrial HVAC applications where durability, space efficiency, and service access are critical. Broad OEM and aftermarket cross references make it a dependable solution for repairs and custom hose assemblies.
