The Turcon® CX(D) is a double-acting sealing system combining a machined elastomer energiser with a low friction Turcon® sealing element. Specifically manufactured to tight tolerances to achieve controlled interference, it exerts a constant and uniform loading on the Turcon® Cap and provides constant positive sealing. Turcon® CX(D) Seals have been used extensively in arduous aircraft applications as both Rod and Piston seals, where low friction, long service life and minimal leakage are requirements. A full range of sizes are offered to suit all MIL-G-5514F and AS4716 grooves. Custom designs available on request.
