The Turcon® T-Seal consists of a T-shaped elastomeric sealing element supported by a Turcon® Back-up ring on both sides. The T-Seal provides a stable base, the semi-circular lip configuration ensuring positive sealing. The side flanges, which form the seal base, offer excellent resistance to rolling and an effective platform to position and energise the anti-extrusion rings. T-Seals have been used extensively in arduous aircraft applications, both as Rod and Piston seals, where long life and zero leakage are requirements. A full range of sizes are offered to suit all MIL-G-5514F and AS4716 grooves. Custom designs available on request.
