spliced o-rings

Darcoid Nor-Cal Seal provides spliced or vulcanized O-Rings made from fluorocarbon, Nitrile, EPDM and Silicone that can be used in environmental sealing and other semiconductor processing applications. Extruded cord stock is available in many standard cross-sections.Spliced or vulcanized O-rings are made from an extruded cord and then vulcanized to form the O-Ring size (ID) required.  Spliced O-Rings are a low cost effective solution when standard O-Rings cannot be used. Darcoid Nor-Cal Seal provides spliced O-Rings with ID’s that range from 5” to 200”. Splices at the joints are almost seamless.

Splicing method created by Darcoid Nor-Cal Seal enables a quick production of O-rings that conform to most industry specifications or to your custom requirements. This technology reduces the manufacturing time for spliced O-rings as well as the cost hurdles associated with custom O-rings. Whether your intended use is prototyping or large-scale commercialization, spliced O-rings deliver a quick-sealing solution

The available standard cross sections are:
0.070”, 0.103”, .0139”, 0.210”, .0275”, 0.312”, 0.375”, 0.500”, 0.750”, 1.000”

If some of your applications may require tighter Cross Section Tolerances, Darcoid Nor-Cal Seal can provide whatever your requirements maybe.

Industries Served:
Oil & Gas, Transportation, Aerospace, Automotive, Mining, Food & Drug, Agriculture, Semiconductor, Chemical, Energy

Advantages of Spliced O-Rings:
• O-rings, Seals can be made from a range of compounds.
• No tooling required for standard ID/OD O-Rings Cord. (typical tooling cost $ 10,000)
• O-rings can be made in virtually any diameter.\
• Shorter  lead  times and faster delivery.
