EAST COAST SHIELDING

Bonded O-Rings

East Coast Shielding is one of the nation’s premier fabricators of O-rings. We offer O-rings in a wide range of material types. In-cluding extruded & vulcanized types of rubber, conductive materials and more. We have O-ring stock available in standard inch sizes, as well as metric. We can also create custom O-rings to meet your specifications. Need an O-ring designed? We can do that too! We are proud to supply O-rings across the country, and around the world, to companies in over a dozen different industries.

SPLICED and VULCANIZED O-RINGS

ECS3 Series & ECS300 Series Capabilities

East Coast Shielding provides spliced or vulcanized O-rings made from conductive & non-conductive 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. East Coast Shielding provides spliced O-rings with ID’s that range from 1” up. Splices at the joints are almost seamless.

Splicing method created by East Coast Shielding enables a quick production of O-rings that conform to most industry specifica-tions 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: 0.040”, 0.062”, 0.070”, 0.103”, 0.139”, 0.210”, 0.275”, 0.312”, 0.375”, 0.500”

If some of your applications may require tighter Cross-Section Tolerances, East Coast Shielding can provide whatever your re-quirements may be.

Advantages of Spliced O-Rings:

  • O-rings or Seals can be made from a range of compounds (ECS3 Series Conductive Silicone & ECS300 Series Non-Conductive Silicone)
  • No Tooling required for standard ID/OD O-Rings Cord
  • O-rings can be made in virtually any diameter and length
  • Shorter lead times and faster delivery than molded rings

O-Ring Cord Cut Length Calculator:

Calculated O-ring Cord Cut Length: ((OD+ID)/2) x Pi = length
(Pi = 3.1416), ID = OD—(2 x C/S)

O-Ring Materials

An O-ring is only as good as the material it is crafted from. East Coast Shielding makes certain that we have a huge selection of top quality materials to choose from:

  • Silicone (ECS300 Series)
  • Fluorosilicone
  • Conductive elastomers (ECS3 Series)
  • Silicone sponge elastomers (ECS300 Series)

Our massive selection of materials guarantees that we can make an O-ring that is right for you no matter what the application. Please ask us about custom material.
