Silicone Hose Off Cut Mixed Box provides a practical assortment of high-quality reinforced silicone hose sections in a range of diameters and lengths. Manufactured with smooth silicone inner and outer layers and reinforced with polyester braid, each hose section offers excellent strength, flexibility, and durability compared to standard rubber hoses. With operating temperatures from -50°C to +220°C (peaks to +250°C), the hoses resist cracking, ozone damage, and heat degradation, making them suitable for both high-performance and heavy-duty applications. The mixed box format is ideal for workshops, custom projects, motorsport builds, and maintenance environments where a variety of hose sizes are required on hand for quick solutions.

Box Contents:

Selection: Mixed off-cuts of reinforced silicone hoses in assorted diameters and lengths.
Diameters: Typically includes sizes ranging from 13 mm up to 152 mm internal diameter.
Lengths: Off-cuts supplied in various short sections, ideal for repairs, testing, or custom setups.

Key Features:

Material: Silicone inner and outer layers for resilience and thermal stability.
Reinforcement: Polyester braid for strength and pressure stability.
Construction: 3–4 ply reinforced wall with smooth bore for efficient fluid and airflow.
Operating Temperature: -50°C to +220°C (peak +250°C).
Working Pressure: From 8.3 bar (smaller sizes) down to 1.5 bar (larger sizes).
Bursting Pressure: Typically 3x working pressure (up to 27 bar).
Standard: SAE J20 R3 compliant.

The Silicone Hose Off Cut Mixed Box provides both convenience and value, offering a versatile selection of hoses for immediate use. Each section is built to the same high specification as full-length silicone hoses, ensuring reliability under thermal cycling, vibration, and pressure fluctuations. Ideal for smaller custom connections, prototype builds, or emergency repairs, the off-cut box supports a wide range of industrial and automotive applications while reducing waste and cost compared to purchasing full lengths.

Applications include automotive coolant and induction systems, turbo and intercooler connections, marine cooling, agricultural machinery, motorsport builds, and industrial fluid transfer. The off-cut mixed box ensures workshops, engineers, and enthusiasts have a ready stock of premium-grade silicone hose sections for quick, flexible, and reliable use in demanding environments.

How to measure ID

Measure the pipe, not the old hose

Heat and age make a used hose swell and go out of round. Take your reading across the metal outlet the hose slides onto — that measurement is your ID.

Use vernier calipers

Set the outer jaws across the widest point of the pipe. A tape measure round a curve reads low by a millimetre or two — enough to buy the wrong size.

Take three readings, keep the largest

Rotate 60° between each. If they disagree the pipe is oval; size to the biggest figure so the hose still seals.

Round to the nearest listed bore

Silicone stretches slightly. If you land between sizes, go down to the smaller bore for a tight seal — never up.

Order by ID, always. Every hose on this site is listed by internal diameter. OD is given for clearance only — it changes with wall thickness and ply count, so it is never the ordering size. On reducers, quote both ends, largest first.

Frequently Asked Questions.

Answers to the questions we’re asked most about sizing, fitment and performance.

Still can't find your answer?

What is in the box?

An assortment of silicone hose sections in mixed diameters and lengths, all the same specification as our full-length product. Supplied in three colours, 3 and 4 ply.

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 silicone is reinforced hose to SAE J20 R3 and the fluorosilicone is the fuel and oil rated equivalent.

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.
