Frequently asked about this part

What is the minimum order quantity for the Medical Silicone O-Ring?

Typically 1,000 pcs. Below that we can still quote, but tooling amortisation starts to dominate the unit price. Sampling and tooling are quoted separately from series production.

What is the lead time for the Medical Silicone O-Ring?

Series production runs 20 days after sample approval. Tool design and T1 sampling add 10–14 days up front, and DFM feedback on your drawing comes back within 48 hours.

What tolerance can you hold on the Medical Silicone O-Ring?

±0.08 mm is the achievable production tolerance for this part family. It covers the dimensions that matter for fit and sealing; we confirm which ones are critical in the DFM memo before tooling is cut.

Which standards does the Medical Silicone O-Ring comply with?

It is produced to ISO 13485 · USP Class VI · ISO 10993-5 · FDA 21 CFR 820. Certificates and test reports are on file and can be forwarded once an NDA is in place.

How is the Medical Silicone O-Ring molded?

By LSR injection, Class 8, in a cell dedicated to that silicone grade. Medical parts are never run on a line that has produced kitchenware — each grade keeps its own press, tooling and QC station.

What hardness and temperature range does the Medical Silicone O-Ring use?

Shore A 50–70, with a service range of -50–200 °C. If your application needs a different durometer in the same geometry, we can usually re-quote the compound without cutting new tooling.
