Tri-Clamp Platinum Cured Gaskets (40RXPX)
- Available in white or clear silicone
- Sizes from 1/2″ up to 8″
- Creates a leak-proof seal between tri-clamp flanges
- Compound Selection Guide
- FDA / USP Class VI Tested [Learn More]
Sanitary platinum cured tri-clamp gaskets are used to make a secure, leak-proof connection between clamp fittings.
A variety of materials are available for selection depending upon medium used inline processing. Gaskets range in size from 1/2 inch to 8 inches.
If you would like a copy of a gaskets certificate, please ask for them at the time of order. Certificates are specific per lot of gaskets. Much like a heat number for fittings, gaskets have what is called a lot number. We don’t log these numbers at the time of order but we do include them on the packaging if you need the certificate after receiving them.
Please see Compound Selection Guide for compatibility information.

Q Are you able to provide a material grade for the platinum-cured silicone you currently are using?...... Read moreThere are no answers for this question yet.
Does Sanitary Fittings have different sized platinum cured silicone tri-clamp gaskets in off-the-shelf options? If so, which sizes? Or do you rely on other distributors? Also, would you be able to you provide the material grade name and technical data sheet associated with the platinum cured silicone tri-clamps? Our company is highly regulated by the FDA, so we need to ensure traceability to the materials that we test and order. Any material that we use in our system needs to undergo internal material testing prior to use. If we order this material, can it be sent with a material certification per order? Thank you.
