Tri-Clamp® Orifice Plate Gaskets - Silicone (Platinum Cured)
Note: Silicone Orifice Plates ship with a blank plate finished to 15 µ-in Ra as standard, but we are happy to accommodate special requests for hole boring (concentric or eccentric), electropolishing, metal detectable elastomers, and custom cut patterns. Click to submit a Request for Quote.
Platinum Cured Silicone Tri-Clamp® Gaskets are 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 curing process of Silicone Gaskets has a direct affect on the amount and type of extractables the hygienic seal will emit. The peroxide curing process leaves residuals of Benzoic Acid (the curing additive) that results in unwanted surface conditions that can lead to product contamination. The platinum curing process eliminates this problem and minimizes 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.
