The Red Dot 70R2116S Tee Splicer is designed for mobile HVAC systems that require a compact three-way refrigerant connection. Because it uses a tee configuration, it allows technicians to split or redirect refrigerant flow without stacking multiple adapters.
This fitting uses male and female O-ring connections, which help ensure a secure seal under high pressure. As a result, it reduces leak risk while maintaining consistent refrigerant flow.
In addition, the steel construction improves strength and durability in demanding environments. Therefore, it performs well in trucks, buses, and off-highway equipment where vibration and temperature changes are common.
Because this tee splicer is widely cross-referenced in OEM and aftermarket catalogs, it is a trusted choice for both service repairs and custom hose assemblies.
