Rubber Radiator Hose Off Cut Mixed Box (RRC) provides a convenient assortment of high-quality radiator hose sections suitable for repairs, replacements, and custom installations. Manufactured from heat-resistant EPDM rubber with high-tensile fibre yarn reinforcement, each hose section offers excellent flexibility, pressure resistance, and durability. The mixed box includes a variety of diameters and lengths, making it ideal for workshops, garages, and maintenance teams requiring quick access to radiator hose solutions. Withstanding continuous operating temperatures from -30°C to +125°C and peaks up to +145°C, the hoses deliver dependable performance in cooling and heating systems across automotive, agricultural, and industrial machinery.

Key Features:

  • Material: Black smooth EPDM rubber inner layer with weather-resistant synthetic rubber outer cover.

  • Reinforcement: High-tensile fibre yarn for strength and pressure stability.

  • Operating Temperature: -30°C to +125°C (peak +145°C).

  • Working Pressure: 7 bar to 10 bar depending on size.

  • Burst Pressure: 21 bar to 30 bar (3:1 safety factor).

  • Internal Diameter Range: 5 mm to 102 mm across mixed selection.

  • Wall Thickness: 5 mm to 6 mm depending on size.

  • Bending Radius: 228 mm to 684 mm depending on diameter.

  • Lengths: Mixed off cuts supplied in practical box format.

Rubber Radiator Hose Off Cut Mixed Box

What is in the box?

An assortment of rubber radiator hose sections in mixed diameters and lengths, all the same specification as our full-length product.

Who is it for?

Workshops, garages, farms, fabricators and anyone who keeps a project going. When you need a short piece at short notice, having a box on the shelf is the difference between finishing the job and waiting for a delivery.

Is it cheaper than buying lengths?

Considerably - you are buying material that would otherwise be trim, so the price per piece is a fraction of the equivalent cut lengths. The trade-off is that you take the sizes as they come rather than choosing them.

Can I choose the sizes?

No, the contents vary - that is what makes them affordable. If you need particular sizes, buy cut lengths or couplers in exactly the dimensions you want. Many customers do both: specific sizes for the job in hand, and a box for whatever comes up next.

Is the quality the same as full-length stock?

Yes - same material, same construction, same standards. These are offcuts, not seconds. The rubber is EPDM radiator hose to SAE J20 R3.

How long are the pieces?

They vary, which is the nature of offcuts - generally short connector and coupler lengths rather than long runs. If you need a specific length, buy a coupler in that size; we stock them in 20 lengths from 50mm to 950mm.
