Description
Overview:
The Radiator Hose 13mm x 1m is a straight length of durable EPDM rubber for engine cooling circuits in automotive and industrial machinery. Supplied as a black, smooth-wall hose, it moves engine coolant between components such as radiators, header tanks, water pumps and thermostat housings. Manufacturer Part Number: 124 0178. With a 13 mm inner diameter and 19 mm outer diameter (approx. 1/2 in I/D and 3/4 in O/D), it offers a sturdy wall for reliable service under vibration. Engineered for long life, it withstands -40°C to +125°C (-40°F to +257°F), resists abrasion, ageing, ozone and weather, and carries typical cooling system pressures up to 4 bar (58 psi). Supplied in a 1 m length (approx. 39.4 in) for straightforward routing and trimming during installation.
Key Features:
- High-quality EPDM rubber construction; black, smooth finish for easy cleaning and routing
- Size: 13 mm I/D (approx. 1/2 in), 19 mm O/D (approx. 3/4 in), length 1 m (approx. 39.4 in)
- Temperature range: -40°C to +125°C (-40°F to +257°F) for dependable operation year-round
- Working pressure: 4 bar (58 psi) for typical automotive and industrial cooling systems
- High tensile synthetic textile outer cover resists abrasion, ageing, ozone and weather
- Flexible straight hose section; simple to trim to length and fit with standard clamps
- Smooth bore helps maintain coolant flow and reduces restriction
- Compatible with water/antifreeze mixtures commonly used in engine cooling
- Not suitable for oil or fuel contact, helping prevent premature degradation
- Approx. weight: 214 g per metre for a robust, stable installation
Typical Applications:
Used for radiator and cooling circuit connections on cars, vans, plant and construction equipment, agricultural machinery, diesel generators, compressors and other stationary engines. Suitable for coolant return lines, bypass lines, header tank feeds and general under‐bonnet plumbing where a straight 13 mm I/D hose is specified. Works with standard hose tails and worm-drive or spring clamps when installed correctly.
