EPDM Automotive Rubber Tube - Coolant & Vacuum Hose OEM/ODM

EPDM Automotive Rubber Tube for Coolant & Vacuum Lines

Our black EPDM automotive rubber tube is the workhorse of under-hood fluid handling: coolant circulation, vacuum routing, fuel vapor, and washer lines. Engineered from automotive-grade EPDM, it resists the ozone, heat, and engine chemicals that crack and harden ordinary rubber tubing within a single season.

Why EPDM for Automotive Tubing?

• Ozone & Weather Proof – EPDM is the industry standard for ozone resistance, so the tube stays flexible in the engine bay for years.
• Coolant & Oil Resistant – Safe with glycol coolants, antifreeze, engine oil splash, and washer fluid.
• Heat Aged for Long Life – Handles -40°C to +120°C continuous, with peak tolerance to +150°C for short hot-soak cycles.
• Uniform Wall Precision – Consistent wall thickness for reliable barb fitting grip and clamp sealing.

Built for Automotive OEM and Aftermarket

Standard sizes (ID 4-25mm) fit most coolant and vacuum applications. Ideal for auto parts manufacturers, engine rebuilders, and aftermarket hose kit suppliers. Available cut-to-length for kits or full 50m rolls for production lines.
