The most demanding applications are best served by JETSEAL’s V-Seals which combine the advantages of compactness, lowest leakage rates, high pressure capability, and high springback.

The V-Seal is one of JETSEAL’s most effective metallic seals. We are able to engineer the optimum seal shape by profiling its cross-section thus providing a carefully controlled variable wall thickness to maximize springback and to optimize the sealing contact force for a specific application.


Because the V-Seal may be designed to generate high contact stress, it is a good solution for very demanding, low leakage rate applications where the joint will remain undisturbed for long periods.

JETSEAL’s V-Seals can also be provided with their own limiter plates to enable sealing between flat (non-grooved) surfaces where the plate provides a load path for the flange bolting load and prevents over-compression of the seal. The seal and limiter plate may also be produced as a single integrated part.
