White Silicone O-Ring

Stock profiles of this type are held in inventory and can ship immediately. Custom extrusions of White Silicone O-Ring take 2-4 weeks, including tooling and production. Expedited service is available if you need the parts sooner.

Yes. We can send prototype samples or run a small trial batch of White Silicone O-Ring so you can test fit, compression set and performance before committing to a production order. Sample policy and freight terms are confirmed together with your quotation.

Yes. We build our own extrusion dies and tooling in-house, which shortens lead times for custom white silicone o-ring and keeps dimensional accuracy and batch-to-batch repeatability under tighter control.

Match hardness to the job, not to habit. Softer compounds seat against rough or pitted flanges and seal at lower closing force; harder compounds resist being pushed into the clearance gap when there is pressure behind the seal. This profile is supplied at 50~65 Shore A - tell us your surface finish and pressure and we will confirm whether that is right.

Give inside diameter and cross-section, plus the groove dimensions if you have them. Cross-section is what fills the groove and does the sealing, so it is the dimension worth tolerancing tightly. A groove drawing is the fastest way for us to check the fit before tooling.

Moulded rings have a parting line where the two mould halves meet. On most static seals it sits away from the sealing face and causes no problem. If your design puts it on the sealing surface, flag it on the drawing so we can discuss the tooling approach.
