Real Feedback from the Field
“Many times, the solution is simply to use the Toruseal® gasket from Specification Rubber because of its ability to catch and stop leak pathways based on its design. I highly recommend the Toruseal® Gasket for the peace of mind that it provides and its reliable performance.”
“This Gasket is far superior to standard flat gaskets. It costs a little more but the reassurance that it will not leak is worth it. We have never had an issue with the Toruseal® Gasket and highly recommend it for its reliable, leak-proof performance and peace of mind.”
