Rubber Wire Reinforced Coolant Hose

Very flexible and tough, spiral wire reinforced and textile braided radiator rubber hose can be cut to length. Smooth bore. Smooth bore EPDM rubber radiator hose, supported by a steel wire helix and textile braids. The outer cover is antifreeze and ozone resistant and has a corrugated shape which gives the hose great flexibility. The hose can operate at temperatures of 100°C, and intermittently to 125°C, making the hose suitable for vehicle radiator and other hot water applications.

Rubber radiator flexible coolant hose is a flexible hose that is used to transport coolant between the engine and the radiator in a vehicle. These hoses are typically made of rubber or a rubber-like material, and are designed to be flexible to allow for easy routing and installation in the tight spaces found in many engine compartments. In addition to their flexibility, rubber radiator hoses are also resistant to heat, chemicals, and abrasion, making them well-suited for use in automotive applications.

What is wire reinforced rubber hose for?
It is a heavy-duty suction and delivery hose - the steel wire helix embedded in the wall stops it collapsing under negative pressure or crushing under load. That makes it suitable for both sides of a pump, for coolant runs that have to turn tight corners without kinking, and for demanding industrial, agricultural and commercial fluid handling where an unsupported hose would flatten.

How is it constructed?
A smooth rubber inner tube for efficient flow, two plies of fabric cord for pressure strength, a high-tensile steel wire spiral embedded in the wall for crush and vacuum resistance, and a smooth rubber outer cover that is antifreeze and ozone resistant. It is built to SAE J20 R3, so it is rated for coolant service as well as general fluid transfer.

What sizes and lengths do you supply?
Internal diameters from 13mm to 51mm, cut to order from 1 metre up to a 20 metre full coil. Order by internal diameter to match the outside diameter of the pipe stub or spigot it will slide over. Buying a full coil works out better per metre if you have several connections to make or a long run to plumb.

When should I use wire reinforced hose instead of ordinary radiator hose?
Whenever the hose has to resist vacuum or crushing. Typical cases are a long lower radiator hose that can collapse as the pump pulls against it, any run on the suction side of a pump, a hose that has to bend tightly without kinking, and hoses in plant and machinery where something may lean or rest against them. For a short, well-supported pressure-side hose, standard reinforced rubber is fine and cheaper.

How do I cut it to length?
Cut the rubber between the wire coils with a sharp blade, then cut through the wire itself with side cutters, and tape or file the exposed wire end so it cannot work its way through the wall or catch on anything. Leave a clean square end and enough straight hose beyond the last coil for the clip to seat on properly.

Will the clip seal properly over the wire helix?
Yes, provided you position it correctly. Site the clip over the section of hose that is fully supported by the pipe stub underneath, and nip it up firmly without crushing the helix flat. If the clip lands directly on top of a wire coil it can deform the wall and create a leak path - move it a few millimetres either way so it bears on the rubber between coils.
