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 spring back.

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 are an effective metallic seal and are suited for critical, low leakage applications. We are able to engineer the optimum seal characteristics by adjusting the thickness at the cross section. Precision machined or roll-formed, V-Seals can be custom designed for high clamping force loads and hard cavity metals or low clamping force loads and soft cavity metals like aluminum.

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.
