Silicone Heater Hose

Versatile and durable, our Silicone Hoses are engineered to elevate your fluid transfer systems to unmatched levels of efficiency and performance. Crafted with precision and innovation, these hoses are designed to excel in a wide range of applications, from automotive and industrial sectors to household and beyond.


Featuring a seamless blend of high-quality silicone rubber, these hoses guarantee exceptional flexibility, resilience, and temperature resistance. Whether you're handling coolant, air, oil, or other fluids, these hoses maintain their integrity even under extreme conditions, ensuring smooth flow and preventing leaks.


Available in a range of internal diameters ranging from 6.5mm all the way to 152mm we have you covered. These are also available in up to 3 vibrant colours Black, Blue and Red. From standard straight hoses to complex bends and shapes, you'll find the perfect fit for your system layout. The vibrant colour options not only lend a modern aesthetic but also signify the dedication we put into ensuring product quality.


Joining cutting-edge technology with rigorous testing, our Silicone Hoses offer unmatched reliability and longevity. Resistant to cracking, UV exposure, and ozone deterioration, they maintain their performance over time, reducing maintenance costs and system downtimes.

What silicone hose do you stock?
Universal straights from 6mm to 152mm, elbows from 6mm to 102mm in 45, 90, 135 and 180 degrees, straight reducers in 61 size pairings, reducing elbows in 43, couplers from 13mm to 152mm, continuous coil, wire reinforced SuperFlex, vacuum tubing, hump connectors, T-pieces and blanking caps - plus a large range of vehicle-specific hoses and multi-piece kits.

What is silicone hose actually better at than rubber?
Longevity and heat. Silicone does not perish, harden or surface-crack with age, heat cycling and ozone exposure, which is what eventually kills every rubber hose. It runs to +250C against about +120C for EPDM rubber, and stays flexible in the cold. The trade-offs are cost and the fact that standard silicone is not fuel or oil compatible.

What is it rated for?
Built to SAE J20 R3 in 3 and 4 ply depending on bore, with a smooth extruded silicone inner layer, polyester braid reinforcement and a silicone outer. Continuous service -50C to +250C, working pressure from around 12.33 bar on small bores to 2.8 bar on large, burst up to 37 bar. Full tables are on each product page.

Can I use it for fuel, diesel or oil?
Not standard silicone - it swells and breaks down in contact with hydrocarbons. Use our fluorolined Fuel & Oil range, built to SAE J30 R6 with a fluorosilicone inner liner, compatible with E5 and E10 pump fuel. Remember this applies to breather and catch-can lines too, which carry oil mist even when nothing liquid is flowing.

How do I choose the right bore?
Order by internal diameter, matched to the outside diameter of the metal pipe or stub the hose slides onto. Measure the pipe itself with vernier callipers, not the hose you are taking off - silicone and rubber stretch in service, so an old hose reads larger than the pipe it was fitted to and will lead you a size out.

What colours do you offer?
Blue, black and red across the standard range; the Fuel & Oil and Classic Wrapped hoses are black only. If you are building a complete system, order all the straights, elbows, couplers and reducers together - shades are consistent within a batch but can differ slightly between them, which shows if you add to a system later.
