HH001034075R – 1" OD x 3/4" ID Heater Hose, 75-Foot Reel

The HH001034075R Heater Hose is a rugged, high-performance rubber hose engineered for fluid transfer in automotive, HVAC, and light industrial systems. With a 1" outer diameter and 3/4" inner diameter, this hose delivers dependable coolant flow while maintaining flexibility and durability under elevated temperatures and moderate pressure conditions. Supplied on a 75-foot reel, it offers convenient length for extended runs and efficient layout in service bays, equipment rooms, or field installations.

Constructed from heat-resistant EPDM rubber, the hose resists cracking, ozone degradation, and chemical exposure, making it ideal for long-term use in demanding environments. Its reinforced wall structure maintains shape and pressure integrity during thermal cycling, while the smooth interior promotes consistent flow and minimizes buildup. The flexible exterior allows for easy routing around bends, brackets, and confined spaces without kinking.

This hose is compatible with standard barbed fittings and clamps, and can be cut to custom lengths for OEM or retrofit applications. It is commonly used in engine coolant systems, heater core connections, auxiliary fluid loops, and other low-to-medium pressure systems requiring thermal stability and reliable performance.
