Ideal for use with our M14x1.5 radiator fan switch, this item is available as a package including a thermal switch in our store.

What Size Adapter Do I Need?

To determine what size adapter you need simply measure the inner diameter of your hose and choose the matching size from our store. The adapter will fit hoses 1mm smaller than it so a 30mm adapter can be used for hoses 29mm-30mm I.D. for example.

Some top radiator hoses are larger at one end than the main body of the hose so if this is the case for your vehicle take care to measure the end that is the same diameter as the part you will cut to fit the adapter.

Available in adapter sizes 26mm, 28mm, 30mm, 32mm, 34mm, 36mm, 38mm and 40mm O.D.


To fit simply cut your hose at a straight section into two pieces using a stanley knife, using a hose clamp lightly tightened around the hose as a cutting guide. Remove approx 30mm length of hose from one of the cut halves which the adapter will replace. Rejoin the two sections with our adapter and the clamps provided and refit the hose.
