The PSI LineBacker gasket is the premium gasket that ensures leak-proof flange seals. Pressure-activated seals provide high confidence sealing, eliminate costly leaks, and provide a solution for fugitive emissions.

The gasket is sized to the bore to protect flange faces from media-induced corrosion and flow-induced erosion. It prevents turbulent flow at flanged connections and mitigates galvanic corrosion in dissimilar metal flanges. High-strength laminate material resists failure due to excess compression. Available to match any flange specification (ANSI, ASME, API, MSS, BS, DIN, AS, others).

The sealing system is not sensitive to low bolt loads - providing reliable sealing through a range of bolt stress. The gasket is self-aligning and centering - quick to install and no special tools are required. Maintenance-free corrosion-resistant design is resistant to deforming under load.
