Silicone Air & Water Coils

Silicone Air & Water Coils collection are a versatile solution for flexible and reliable hoses in air, water, and heating systems. From the durable 3 Ply Continuous Air and Water Hoses to the practical 2 Ply Radiator Heater Hoses and Vacuum Extruded Hoses, we've got all the coils you need for straightforward connections.

When it comes to air and water systems, our 3 Ply Continuous Hoses are sturdy and dependable. They're designed to handle continuous airflow and water circulation with ease, making them perfect for various applications.

For heating systems, our 2 Ply Radiator Heater Hoses are a reliable choice. They ensure a smooth flow of coolant, helping your vehicle stay at the right temperature in colder weather.

Need a hose that can handle vacuum pressure? Our Vacuum Extruded Hoses are designed for just that. They're ideal for applications where suction is involved.

What is a silicone coil and why buy one?
It is silicone hose supplied in a continuous length rather than short moulded sections, so you cut exactly what you need from one piece. Buy a coil when a 1 metre length will not reach, when you have several runs of the same bore to make, or when you are plumbing a system from scratch and want to avoid unnecessary joins.

What is in the range?
Continuous 3 and 4 ply silicone hose in 13mm to 51mm, in coils from 1 to 5 metres, in red, blue and black. The 2 ply radiator and heater hose in 6mm to 25mm, in lengths from 1 to 50 metres. And silicone vacuum tubing in thirty size combinations from 3mm x 7mm to 10mm x 16mm, in coils up to 30 metres, in blue, red, black and clear.

How much should I buy?
Measure the run with a piece of string following the exact route including bends, then add a margin for trimming and for the odd mistake. Longer coils work out better value per metre, and offcuts are always useful. If you are replacing both a feed and a return, do them together - they are the same age and the second will fail soon after the first.

What are they rated for?
The continuous hose is multi-ply fabric-reinforced silicone to SAE J20 R3, suitable for coolant, air and general fluid transfer. The 2 ply hose is rated -30C to +200C at 18 to 24 bar. The vacuum tubing is unreinforced VMQ silicone rated -60C to +180C. None of them is suitable for fuel or oil - use the fluorolined range for that.

Can I use the vacuum tubing under pressure?
For low-pressure signal lines to a gauge or solenoid, yes. It is unreinforced, so it is not a pressure hose and should not be used for charge air, pressurised coolant or anything where a failure matters. Under sustained pressure it will balloon and eventually split. Use reinforced hose for anything carrying rather than sensing pressure.

Will an unreinforced coil collapse under vacuum?
The vacuum tubing wall thickness is chosen to hold its shape at normal manifold vacuum in the sizes offered. It is not for the suction side of a pump or for strong sustained vacuum in larger bores - for those you need a hose with a wire helix. Our SuperFlex wire reinforced silicone covers 6mm to 51mm and is made for that duty.
