Description
Overview:
This reinforced radiator hose is a flexible EPDM rubber line for engine cooling circuits in cars, vans, light commercial vehicles, and plant machinery. It has a 45 mm inner diameter (1 3/4 in ≈ 44.5 mm), 55 mm outer diameter, and a 1 m length, making it suitable where a straight section is required. The construction uses durable EPDM for long service life and resistance to heat, ozone, and coolant. The hose operates from -40°C to 120°C and handles up to 150 psi (about 10 bar) when correctly clamped. Supplied as a straight length that can be cut to size, it is ideal for connecting radiators, header tanks, thermostats, and engine inlets/outlets. Manufacturer Part Number (MPN): 010 045.
Key Features:
- Reinforced EPDM rubber for strength, flexibility, and resistance to ageing and cracking
- 45 mm ID (1 3/4 in ≈ 44.5 mm), 55 mm OD, 1 m straight length for easy routing and trimming
- Heat resistant from -40°C to 120°C for reliable performance in demanding engine bays
- Rated up to 150 psi (approx. 10 bar) when used with suitable clamps and fittings
- Smooth-bore design aids coolant flow and reduces pressure drop across runs
- Black, flexible construction simplifies installation in tight spaces and around components
- Compatible with standard engine coolants and antifreeze mixes typically used in passenger and light commercial engines
- Cut-to-length convenience helps reduce waste and match OEM run lengths
- Suitable for maintenance, repair, and custom plumbing where a straight flexible hose is needed
- MPN 010 045 for easy identification and reordering
Typical Applications:
Used for radiator connections, bypass lines, header/expansion tank links, and thermostat-to-pipe runs on vehicles and machinery that require a 45 mm ID straight hose. Common in automotive cooling systems, generators, industrial engines, and construction or agricultural plant. Ideal for replacing aged or perished hoses during scheduled servicing or engine rebuilds. Always check space, routing, and diameter before fitting.
