XL Type 1 Sanitary Tri-Clamp Gaskets (40MP)
These standard type 1 sanitary tri-clamp gaskets are used to make a secure, leak-proof connection between extra large tri-clamp fittings (8"-12").
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.
