With over 15 years development, Tihai Sealing Products Co.,Ltd. have become a leader China o ring seal manufacturer of seal components and machine tool accessories. We had obtained international certificate of ISO9001:2000 and QS9000 in 1996 and got the certification of ISO/TS16949 in 2003. And we produce all kinds of customized o ring seals in varies materials of engine system (including exhaust system and muffler) in automobiles and motorcycle. While producing products of our own brand, we also provide OEM products with origin production of some famous brands such as B+S, NOK, TTO, VALQUA and DZ.

O-rings are a Seal Science specialty. Utilizing advanced material science, SSI provides O-ring solutions in many types of elastomeric/ rubber compounds. SSI incorporates advanced materials in its design methodology ranging from Perfluoroelastomers to alloy filled conductives elastomers.
SSI utilizes on-site molding making capabilities to provide molded O-rings from .030” inches OD to over 40.0 inches. SSI has the capability for performance molding of O-rings with ultra critical measurement tolerances, as well as providing less critical, economically costed, high volume supply alternatives.
Seal Science incorporated finite element analysis (FEA) in its O-ring design to develop the most optimal size seal for an application.

O-rings are typically available in standard sizes per industry standards. These include "AS568" standard sizes (001-475), "AS568-" boss gasket sizes (901- and up), British Standard metric sizes, JIS standard sizes, JASO standard sizes, AS871, and custom. When custom o-rings are required, the width or thickness, insider diameter, and outside diameter are important to consider. Common materials of construction for o-rings include butyl (-75° to 250° F), cast polyurethane (-40° to 125° F), ethylene propylene (EPDM) (-70° to 275° F), fluorosilicone (-100° to 350° F), fluorocarbon/fluorosilicone blend (-25° to 400° F), highly-saturated nitrile (-40° to 300° F), Hydrin (-60° to 300° F), neoprene (chloroprene) (-45° to 230° F), nitrile (Buna-N) (-30° to 275° F), polyacrylate (-25° to 350° F), polyurethane (Millable) (-40° to 180° F), SBR (BUNA-S) (-30° to 275° F), silicone (-65° to 450° F), and Thiokol (-30° to 300° F). Exact specifications should be clarified by the vendor, as chemical and physical properties of an O-ring can differ based on manufacturing technique.
