The 70R7650 90-degree heater hose connector is engineered for applications that require an angled transition between a #8 O-ring fitting and a 5⁄8″ heater hose. The elbow configuration allows improved hose routing in confined engine bays, helping reduce kinks and stress on hoses.
Commonly used in truck, bus, agricultural, and heavy-duty HVAC and engine-cooling systems, this connector is well-suited for repairs, retrofits, and custom plumbing layouts. Broad OEM and aftermarket support makes it a reliable replacement option across multiple platforms.
