70R2072S Red Dot 12 × 12 Straight Splicer Steel Fitting with R134a Quick-Disconnect Service Port (13 mm)

The Red Dot 70R2072S Straight Splicer with R134a Quick-Disconnect Service Port is designed to join two same-size 12 × 12 refrigerant hoses in mobile HVAC systems. Because it uses a straight splicer design, it allows clean, inline repairs without changing hose routing.

This fitting features a 13 mm R134a quick-disconnect service port, which allows technicians to evacuate, charge, and service the system using standard R134a couplers. As a result, it improves service speed and reduces the need for additional fittings.

In addition, the steel construction increases strength and helps extend service life in high-pressure A/C environments. Therefore, it performs well in trucks, buses, and off-highway equipment that operate in demanding conditions.

Because this fitting appears across many OEM and aftermarket catalogs, technicians often rely on it as a trusted replacement part for mobile refrigeration service.
