Product Overview
Banjo Seals have been specially designed to meet the requirements of very high pressure applications in the automotive and trucks sectors. They offer significant advantages over copper or aluminum washers. Thanks to the elasticity of the rubber, they ensure an extremely reliable sealing. Their self-centring lip makes assembly much easier, offering optimum installation comfort.
