Original Press Release:

Qosina Stocks Medical-Grade O-Rings

Qosina is pleased to carry a line of bulk, non-sterile O-rings for further assembly. These O-rings are predominantly used in static sealing applications and can be used between two components as a primary seal to prevent leakage, or as an energizing element. When used as an energizing element, the O-rings provide the necessary initial tension required to keep a non-elastic seal in place so that the sealing edge is pressed to the counterpart.

Qosina stocks O-rings in medical-grade EPDM and silicone, both of which offer excellent heat resistance and have suitable ozone and aging properties. Packaged in bags of 100, these cost-effective O-rings are available in various sizes, ISO Class 8 Clean Room manufactured and packaged, and are ideal for a number of applications. Qosina’s O-rings can also be used to speed up the product development process and help minimize component design costs.
