Aviation Bulb Seal

A P-seal is one of the most common aircraft seals, used in a variety of applications ranging from electrical systems to engine gasket sealing. Also referred to as a bulb seal due to its shape, p-seals bond tightly, and aviation mechanics often utilize them to prevent the leakage of oil, fuel, air, hydraulic fluid, and more.

The p-seals offered by Brown Aircraft use high-heat silicone and the finest in sealing materials. These bulb seals are designed to withstand the cold temperatures of high altitude; while resisting corrosion and damage that can be presented by a variety of aircraft systems.
