About this product

Product information from the supplier.

Our High Transparency Platinum-Cured Silicone O-rings and Gaskets are engineered for the most demanding sanitary environments. Utilizing a premium platinum-curing process, these seals eliminate the risk of taste or odor impartation, making them the gold standard for pharmaceutical, biotechnology, and high-purity food and beverage production facilities.

Designed to maintain ultrapure water and CGMP process fluid standards, our silicone seals offer exceptional flexibility at low temperatures and superior resistance to steam, radiation, and ozone. Whether you require standard AS568 sizes or custom-engineered dimensions, our milled gum silicone construction ensures maximum resistance to tearing and deformation compared to traditional molding methods.

Frequently Asked Questions

Q: What is the difference between peroxide-cured and platinum-cured silicone?

Platinum-cured silicone is more pure, odorless, and tasteless. It avoids the by-products associated with peroxide curing, making it essential for FDA, USP Class VI, and food-grade applications.

Q: Can these O-rings be used in pharmaceutical autoclaves?

Yes, our Platinum-Cured Silicone gaskets are specifically designed to be autoclaved, irradiated, and gas sterilized without degrading their structural integrity.

Q: Do you provide custom sizes outside of AS568 or JIS standards?

Absolutely. We offer full OEM services and can manufacture custom O-rings and gaskets based on your specific ID, OD, and Cross Section (CS) requirements.

Q: Which material is best for oil resistance vs. temperature resistance?

For high-temperature and sanitary needs, Silicone is best. For excellent oil resistance at a lower cost, NBR (Buna-N) is recommended. For ozone and weathering, EPDM is the ideal choice.

Q: How do I ensure the O-ring won't impart taste to my food product?

By choosing our Platinum-Cured Silicone. Unlike standard rubbers, the platinum catalyst process ensures no volatile organic compounds are released, keeping your products tasteless and odorless.

Q: What is the typical lead time for custom rubber parts?

Orders without molding typically take about 15 days, while orders requiring new molds may take longer depending on the complexity. Stocked items ship within 1-2 business days.
