Automotive Boot Seals

Boot seals, also known as top seals, are used on cars, vans and other automotive vehicles to protect edges and create a long-term watertight sealing solution. Although they are commonly used to seal boots, the sponge sealing bulb situated on the top of the edge trim allows these sections to be used for any application where the lid closes directly down onto the top of the protruding panel edge. This includes sealing bonnets, doors or other automotive applications where there is a vertical panel.

Boot seals are manufactured with two parts; a metal reinforced edge trim that clips onto the panel edge, and a sponge rubber sealing bulb that compresses to create a seal. The metal spine within the edge trim creates a strong section that is able to withstand impact as well as offering a level of protection to the underlying surface. The sponge bulb on the top of the section is manufactured from a compressible closed-cell sponge rubber that does not absorb moisture or water.

To identify the best product for your vehicle, you will need to measure the thickness of the panel edge and determine the size of the gap that needs to be sealed. It is recommended that you choose a section with a sponge sealing bulb approximately a third bigger that the size of the gap. For example, a boot seal with a 15mm diameter top seal will be suitable for a 10mm gap.
