Measure the mean circumference of the groove and add a small allowance for compression or thermal expansion, depending on the application.
O-Ring Cord Stock Component Intelligence
Engineered elastomer cord for custom-fit sealing solutions
What are O-Ring Cord Stock components?
O-ring cord stock is a versatile, cut-to-length elastomer used for custom-sized seals and gaskets. Selection depends on the cross-section diameter, material durometer, and chemical compatibility with the operating environment.
How to Choose O-Ring Cord Stock Components
Selecting the correct cord stock requires balancing mechanical fit with environmental exposure.
Material Compatibility
Match the elastomer (e.g., Nitrile, Viton, Silicone) to the fluid or gas exposure to prevent swelling or degradation.
Durometer Selection
Choose hardness based on pressure requirements; higher durometer resists extrusion in high-pressure gaps.
Cross-Section Accuracy
Ensure the cord diameter matches the groove width to maintain proper compression and seal integrity.
Temperature Range
Verify the material's glass transition and degradation temperatures against your system's thermal profile.
Bonding Method
Consider the adhesive or vulcanizing process required to join the ends into a continuous loop.
