O Ring Size
IBG sealing offers AS568 standard o-rings,metric,ISO3601,JIS B2401, and custom sizes in a wide variety of materials.

Seal design is an important factor in food,dairy,beverage and pharmaceutical processing.

An o-ring is a very important part of that seal.
An o-ring is a doughnut-shapes seal manufactured in a special elastomer.
O-rings are generally installed in a seal to prevent leaking and unwanted escape or loss of fluid.


USP Class VI,Food Grade Platinum-cured Silicone Washer, Silicone Gasket, Silicone O-rings
Silicone is the material of choice in Pharmaceutical applications, and in sanitary water systems when PTFE
is not feasible due to severely misaligned fittings.Platinum-cured silicone is very flexible at low temperatures and will not impart any taste or odor.The operating rang is -55℃ to 250℃ and is manufactured in clear, white and red.
Silicone is available in Phthalate free or metal detectable/x-ray 

Platinum-Cured Silicone O-ring/Gasket

Is an excellent choice for use in production facilities for pharmaceutical, biotechnology, high-purity water, and food/beverage products. Silicone Sanitary Gaskets can withstand temperature extremes, radiation, corona, ozone exposure, moisture and steam. We recommend considering Silicone Gaskets when it is not feasible to use PTFE Gaskets due to severely misaligned fittings, or if the cost of high pressure clamps outweighs the benefits of PTFE (extended service life). Unlike PTFE, Silicone gaskets are very flexible at low temperatures. They are also odorless, tasteless, non-toxic, and hygienic. With the ability to be autoclaved, irradiated and gas sterilized, Platinum Cured Silicone Gaskets provide you with the ultimate high purity contact surface. The platinum curing process minimizes the reaction between the gasket and process fluids. These gaskets are post cured and will not cause cell mutation or growth retardation. Our Platinum Cured Silicone Gaskets maintain and uphold ultrapure water and CGMP process fluid standards. These gaskets have been manufactured from milled gum silicone which offers superior resistance to tearing and deformation when compared to traditional liquid injection molding silicone.
