Description
This 5/8" Inside Diameter (I.D.) Rubber Heater Hose is a premium, flexible bulk solution for custom plumbing automotive cooling networks, passenger compartment heater cores, or engine-swap plumbing. Sold continuously by the foot, ordering bulk hose allows you to cut exact custom lengths to reduce extra engine-bay clutter and eliminate unnecessary mid-line splice fittings.
Heavy-Duty Structural Design
EPDM Rubber Construction: Forged from durable, high-grade Ethylene Propylene Diene Monomer (EPDM) synthetic rubber. This compound is engineered to resist degradation from heat, ozone, road grime, and harsh environmental weathering.
Reinforced Wall Strength: Features woven internal reinforcement layers that help the hose withstand standard cooling system pressures and resist high-vacuum kinking on tight radiuses.
Chemical Shield Formulation: Specially treated to handle continuous contact with common automotive glycol-based coolants and factory anti-freeze mixtures without hardening, cracking, or blistering from the inside out.
Critical Safety Restrictions
⚠️ Important: This hose is designed strictly for coolant loop transfer. Do not utilize it for fuel lines, oil lines, brake lines, or transmission fluid loops. The chemical composition of petroleum products will dissolve EPDM rubber from the inside out, causing rapid hose failure and dangerous fluid leaks.
