Rubber Cotton Braided Fuel Hose is a flexible, reinforced hose designed for the safe transfer of fuels, oils, and other petroleum-based products in automotive, agricultural, and industrial applications. Constructed with a high-quality rubber inner lining and an external cotton braid reinforcement, the hose combines flexibility with strength, ensuring reliable performance under pressure and resistance to abrasion. Its classic braided finish provides both durability and an authentic appearance, making it suitable for use in restoration projects as well as modern fuel systems. Engineered to handle petrol, diesel, and oil, the hose delivers consistent reliability and long service life in demanding environments.

Key Features:

Material: Rubber inner tube for compatibility with fuels and oils.
Reinforcement: Cotton braid covering for strength, flexibility, and abrasion resistance.
Construction: Flexible rubber hose with external braided finish.
Operating Temperature: Suitable for use across a wide thermal range in fuel systems.
Applications: Designed for petrol, diesel, oil, and other hydrocarbon transfer.
Appearance: Traditional braided outer finish for a durable and period-correct look.

The rubber inner lining ensures safe and reliable handling of fuel and oil, while the cotton braid reinforcement protects against external wear and mechanical stress. The braided covering adds strength without sacrificing flexibility, making installation straightforward even in confined spaces. Resistant to cracking, abrasion, and vibration, the hose provides dependable performance for both modern and classic vehicles, as well as agricultural machinery and general fuel handling tasks. Its combination of traditional braided appearance and modern reliability makes it a popular choice for restoration work where period-correct detailing is important.

Applications include use in automotive fuel lines, oil transfer, agricultural equipment, marine systems, and general-purpose machinery. Rubber Cotton Braided Fuel Hose is widely used by restorers, enthusiasts, and engineers for its proven reliability, flexible installation, and durable braided construction.

How to measure ID

1

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.

2

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.

3

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.

4

Round to the nearest listed bore

Never go up: a bore wider than the fitting will not grip, whatever the hose is made of. If you land between listed sizes take the smaller bore, and secure it with a clip.

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 it used for?

Transferring petrol, diesel, lubricating oils and other hydrocarbons in automotive, marine, agricultural and industrial systems.

What size and length do I order?

Order by internal diameter, matched to the outside diameter of the pipe stub or spigot it slides over. Measure the pipe with vernier callipers rather than the old hose, which stretches in service and reads large. Available in internal diameters from 3mm to 12mm, lengths from 1 Metre to 50 Metres (Full Coil). Full coils work out considerably better value per metre than cut lengths.

What standard is it built to?

It is manufactured to DIN 73379 Type B. Buying to a recognised standard matters here - it means the construction, pressure rating and performance have been benchmarked rather than simply described.

Is it compatible with E5 and E10 petrol?

Yes - the nitrile-based compound is formulated for modern ethanol-blended fuels as well as diesel and oils. Ethanol attacks unsuitable rubber from the inside, so an older line can look perfectly sound externally while breaking down internally and shedding debris into the fuel system.

How do I know when it needs replacing?

Squeeze it. Hard and brittle, or spongy and swollen, both mean it is done. Look for surface cracking when you flex it and crusty residue or staining round the clips, which indicates seepage. Replace on condition rather than waiting for a failure.

How should it be secured?

Proper hose clips, one at each end, positioned squarely over the barb or spigot. Support long runs with rubber-lined P-clips so the hose cannot chafe against a bracket, panel or wiring loom, and keep it clear of exhaust components.
