Rubber Coupling Hose from HosesUK is designed to provide durable and reliable connections between rigid pipework or hose sections in automotive and industrial systems. Manufactured from heat-resistant EPDM rubber and reinforced with high tensile fibre yarn, the hose maintains strength and flexibility under demanding conditions. Its wrapped outer finish ensures added durability and protection against weathering and abrasion, making it suitable for long-term use in coolant and fluid transfer applications. Key Features: Material: Black smooth EPDM inner with wrapped weather-resistant synthetic rubber outer. Reinforcement: High tensile fibre yarn for strength and durability. Internal Diameter Range: 5 mm to 102 mm. Wall Thickness: 5–6 mm depending on size. Working Pressure: 7–10 Bar (varies by size). Burst Pressure: 21–30 Bar (minimum 3x working pressure). Temperature Range: -30°C to +125°C, peak +145°C. Standard: SAE J20R3 compliant. The HosesUK rubber coupling hose is specifically engineered for joining coolant and fluid lines, offering a short, straight connection that resists collapse under pressure. Reinforced for strength and reliability, it provides consistent sealing performance while remaining flexible for installation in tight or complex layouts. The wrapped outer layer increases resilience to abrasion and environmental stress, ensuring dependable service life. Common applications include radiator and coolant system couplings, air and water transfer, and industrial hose-to-pipe connections. Available in a wide diameter range, the HosesUK rubber coupling hose offers a versatile and robust solution for both professional and maintenance use.
