EXORACING / HEAT MANAGEMENT

Find the right sleeve for your AN hose.

Choose your Exoracing hose to see its published dimensions and compare heat sleeve sizes.

1. Choose your hose

Different hose constructions can have different outside diameters in the same AN size.

Does the sleeve need to pass over a fitting?

For sewn and silicone sleeves, enter the largest fitting or connector they must slide over. Velcro sleeve opens around the hose, so its size still uses the hose diameter.

2. Compare heat sleeves

Choose your hose to see sizes

We choose the smallest listed sleeve ID above the diameter it must cover. Check actual hose size, fittings and bends before ordering.

Your sewn, Velcro and silicone sleeve sizes will appear here after you choose a hose.

Temperature ratings describe different exposure conditions. A short-term limit is not a continuous working temperature. Read the selected product's specifications and keep the protected line clear of the heat source.

AN size is a label, not a measured hose diameter. These are Exoracing's published dimensions, not a universal chart for other brands. This finder compares dimensions; confirm fluid, pressure, temperature and hose-end compatibility for your system.
