The Red Dot 70R2012S Straight Splicer Fitting is designed to connect 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 uses steel construction, which adds strength and long service life in high-pressure A/C systems. As a result, it performs well in trucks, buses, and off-highway equipment that operate in demanding conditions.
In addition, the 70R2012S does not use threads or ports. Instead, it installs directly between hoses of the same size. Therefore, it works well for hose repairs, system modifications, and custom hose assemblies where space is limited.
Because this fitting appears across many OEM and aftermarket catalogs, technicians often choose it as a trusted replacement part for mobile refrigeration service.
