About O-Rings
O-Rings are used in a variety of life science applications either as sealing elements or as energizing elements for Glyd Ring® seals and Wipers.
Our medical grade O-Rings are both cost-effective and perform excellently in the most demanding of environments. No matter if you need metric or inch, standard or custom-made O-Rings – any size of O-Ring seal is available – including Giant O-Rings using our Fleximold™ process.
Materials Specific to Healthcare & Medical
Today, the O-Ring is the most widely used seal because of its inexpensive production methods and its ease of use. We offer O-Rings in a range of elastomeric materials specifically for life sciences applications that allow sealing of practically all liquid and gaseous media, while standing up to even the most rigorous sterilization processes.

Application Examples
Metered Dose Inhaler
Customer: Medical Device Manufacturer
Application: Metered Dose Inhalers
Issues:
- Perfect surfaces without trimming required
- Mold join burr must be <0.05 mm / .002 inch
- Requires standard volume of 7.464 mm3 to minimize evaporation and remain tight against high-pump pressure
- Cleanroom manufacture for high-cleanliness needed
Solution
- Precision micro-sized silicone O-Ring produced in cleanroom
The inhaler produces a gentle cloud, leaving plenty of time for the user to inhale the medication. The O-Ring prevents medication in the dosing chamber from running back down the capillary. The seal is manufactured to extremely tight tolerances in a cleanroom environment to meet the requirements of the application.
Pharmaceutical Centrifuge
Centrifuge Housing Seal
Customer: Centrifuge manufacturer
Application: Centrifuge housing seals
Issues:
- High centrifugal forces put extreme demands on physical properties of seals
- Needed to fit in seal groove without dead spaces for ease of cleaning
- Compatibility with harsh cleaning media required
- Compliant with FDA and USP Class VI standards required
- Large size meant tooling costs prohibitive
Solution
- FlexiMold™ O-Ring in Isolast® J9515
Due to the low volume requirement, the cost for a tool was prohibitive. An O-Ring using the FlexiMold™ process was therefore selected. By this proprietary production method, an O-Ring can be fabricated that has the same characteristics as a molded O-Ring without the need for a dedicated tool
The giant O-Rings were delivered in record time and provided the same integrity as compression molded O-Rings without the tooling costs.
