Rubber Heater Hose

Rubber Heater Hose is a high-quality, heat-resistant hose designed for the transfer of hot water and coolant in automotive, agricultural, and industrial systems. Constructed with a smooth black EPDM inner tube, reinforced with high-tensile fibre yarn, and protected by a weather-resistant synthetic rubber outer layer, the hose delivers excellent flexibility, durability, and thermal stability. Conforming to SAEJ20R3 standards, Rubber Heater Hose provides reliable performance under continuous operating temperatures from -20°C to +100°C, with short-term peaks up to +120°C. Its robust design ensures efficient coolant circulation while resisting cracking, ozone, and ageing in harsh working conditions.

Key Features:

• Material: Smooth heat-resistant EPDM inner tube with synthetic rubber outer layer.

• Reinforcement: High-tensile fibre yarn for pressure strength and dimensional stability.

• Operating Temperature: -20°C to +100°C (peak +120°C).

• Working Pressure: 10 bar across all sizes.

• Burst Pressure: 30 bar (3:1 safety factor).

• Internal Diameter Range: 16 mm to 25 mm.

• Wall Thickness: 4.5 mm to 5.5 mm depending on size.

• Bending Radius: 150 mm to 216 mm depending on diameter.

• Standard: SAEJ20R3 compliant.

The EPDM rubber construction provides excellent resistance to heat, coolant additives, and weathering, ensuring long-term durability in demanding environments. Its fibre reinforcement maintains stability under pressure while allowing flexibility for installation in confined spaces. The smooth bore design supports efficient coolant flow, reducing the risk of overheating or performance loss in engine and machinery systems. The outer synthetic rubber layer resists abrasion, ozone, and environmental wear, making the hose suitable for prolonged service life in both indoor and outdoor use.

Applications include engine cooling and heating systems, agricultural and construction machinery, marine engines, and general-purpose hot water or coolant transfer. Rubber Heater Hose is widely used in automotive, industrial, and agricultural sectors where reliability, heat resistance, and flexibility are critical for system efficiency and safety.
