Size Guide

Measure the outside diameter of the pipe the hose will fit onto, not including any bead. That figure is the internal diameter to order. Most sizes stretch 1–2mm with lubrication, so a 70mm hose will usually fit a 71–72mm pipe.

Internal Diameter Leg Length Wall Working Pressure Burst Pressure
6mm – 48mm 100mm Approx. 4.5mm, 4-ply silicone, 3-ply polyester Over 7 bar Over 10 bar
51mm – 68mm 100mm Approx. 5.4mm, 5-ply silicone, 4-ply polyester Over 9 bar Over 12 bar

Frequently Asked Questions

How do I choose the size?

Measure the outside diameter of the pipe you are connecting to. That is the internal diameter of hose you need.

Will it fit a slightly bigger pipe?

Most sizes stretch 1–2mm with lubrication, so a hose can usually go 1–2mm over its nominal size.

Can I use it for intercooler and turbo pipework?

Yes. It is reinforced for boost pressure. Stainless T-bolt clamps are recommended on high-boost joints.

What warranty do I get?

Stoney Racing silicone hoses carry a 3-year warranty.
