Description
Overview:
The Heater Hose 19mm (3/4") x 20m is a coolant-resistant rubber hose designed for moving water-based antifreeze through engine and heating circuits. Made from high-quality, flexible rubber and rated for -40°C to +100°C, it provides reliable service across a wide range of conditions. With a 19 mm (3/4 in) internal diameter and a continuous 20 m length, it is suitable for cars, vans, light commercial vehicles, plant equipment, generators, and agricultural or garden machinery with liquid-cooled engines. The smooth-bore, black rubber construction helps maintain steady coolant flow and withstands typical engine-bay environments. Supplied as a long reel, it can be cut to length and secured with standard hose clips for straightforward repairs, maintenance, or custom installations. MPN: 605 093.
Key Features:
- 19 mm (3/4 in) internal diameter for common heater and coolant circuits
- 20 m continuous length to minimise joints and potential leak points
- Coolant-resistant rubber for durable, long-lasting performance
- Temperature range -40°C to +100°C for year-round reliability
- Flexible and easy to route; simple to cut to size with a sharp blade
- Smooth inner bore helps maintain consistent coolant flow
- Black finish suits most engine bays and hides grime
- Compatible with standard worm-drive or spring hose clamps
Typical Applications:
Used for heater core feed and return lines, radiator-to-heater connections, bypass and degas lines, and header tank links. Suitable for automotive cooling circuits in cars and vans, cab heaters on construction and agricultural machinery, stationary engines and generators, and ride-on mowers or compact tractors that use 19 mm (3/4 in) heater hose for coolant transfer.
