Leader GT SRI style is a winding with an inner and an outer guide ring. A wide array of filler options are available and include high purity inhibited grade flexible graphite, expanded PTFE, Leaderfite, Ceramic, and LeaderTHERM for high temperature applications. Consistent repeatable load and density characteristics are built into every gasket due to our advanced automated winding and assembly equipment. Every Leader spiral wound gasket has a unique traceability number stamped in the outer ring to allow complete confidence in quality of materials supplied. All special alloys are 100% PMI inspected to insure proper materials of construction.
This gasket consists of a metal guide ring (or sometimes referred to as a centering ring) and a spiral wound sealing element with an inner ring to enhance gasket performance. Inner rings are required for gaskets with PTFE filler according to ASME B16.20 standards and considered important for flexible graphite fillers. The inner ring is normally made of the same alloy as the winding material.

Industry standard sealing solutions for pressure piping and vessels in the chemical and refining markets.
The inner ring is added to prevent the possibility of inward buckling into the pipe during installation, to protect the sealing element from extreme temperatures and mediums, fill the void between flanges to prevent erosion of the flange and to reduce the possibility of failure. Gaskets are manufactured in accordance with all Global Industry Standards including ASME and EN/DIN. Leader GT assures strict adherence to these specifications as routine inspection procedures are applied throughout the manufacturing process. Leader maintains 100% traceability of all materials and finished goods used in our manufacturing process. Leader Global Technologies maintains an ISO 9001-2000 Certification.
This profile is normally used in raised and flat faced flanges.
