Simple in shape, the O-Ring is most commonly used in static sealing applications where simple, cost-effective leak tight performance is required. O-Rings can be supplied against all internationally recognised size standards, and can be produced in all aerospace type elastomers. These include Nitriles (NBR), Ethylene Propylene Dieme Monomers (EPDMs), Fluorosilicones (FVMQ), Fluorocarbons (FKM) and Perfluoroelastomers (FFKM), including the almost universally chemically resistant Isolast®. Non-standard sized O-Rings are available on request. In addition, special O-Rings can be supplied with their flashline in a specified position on the seal or inspected to stringent criteria, if required.

The Turcon® AQ Seal® 5 is a patented development of the proven standard AQ Seal®. The Turcon® AQ Seal® 5 is a double-acting piston seal designed for reciprocating or helical applications. Comprising a dynamic sealing element in Turcon®, with a limited footprint elastomeric QUAD-RING® seal, inserted centrally into its sealing face. The seal ring is energised by two elastomeric O-Rings. The Turcon® AQ Seal® 5 is highly recommended in applications requiring media separation. A range of sizes in the 300 and 400 series are offered to suit MIL-G-5514F and AS4716 bores. Custom designs available on request.

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.

The Turcon® CX(S) is a single-acting sealing system combining a stepped elastomer energiser with a low friction Turcon® sealing element. Specifically manufactured to tight tolerances, the stepped elastomer energiser achieves controlled interference, exerting a constant and uniform loading on the Turcon® Cap. The small elastomer lip profile affords excellent leakage control under static and low temperature dynamic conditions, while still maintaining low levels of breakout and running friction. Turcon® CX(S) Seals have been used extensively in arduous aircraft applications as Rod 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.

The Turcon® Variseal® W is a single acting sealing element optimised for low to medium pressure fluid sealing. Available in both piston and rod configurations, metric and AS4716 sizes. The unique characteristic of the slant coil spring, means the spring force is relatively constant over a wide deformation range, giving a controllable and constant friction. The chemical resistance of the Turcon® material and metallic slant coil spring gives almost universal compatibility with fluids or chemicals and its wide temperature range allows it to be used under extreme conditions. In addition, the Turcon® Variseal® M2 has unlimited shelf life.

The Turcon® VL-Seal® has been developed over the last few years as a new generation, unidirectional rod and piston seal. The design is based on the latest sealing theories and practical experience, tested both in-house and in conjunction with customers, to give optimised performance. The design features the Stepseal® back pumping effect. The Turcon® VL-Seal®™ uses standard sized O-Rings and are offered to suit MIL-G-5514F and AS4716 grooves.

The Turcon® Wedgpak® consists of a proprietary triangular elastomer sealing element, supported by two Delta shaped Back-up Rings, that prevent the elastomer sealing element from spiralling or rolling under severe working conditions. The small elastomer contact area of the Wedgpak® design, results in a slipper seal type performance, with low static and dynamic friction. At the same time, the elastomer wipes the surface efficiently, providing excellent leakage control. The Wedgpak® Back-up Ring provides support and extrusion protection for the elastomer sealing element. A full range of sizes are offered to suit all MIL-G-5514F and AS4716 grooves.
