“I can say with all honesty that there has never been a callback or failure of any Toruseal® gasket on my projects. The service from my sales rep, Matt Haan, is excellent. His industry knowledge and enthusiasm are contagious. Matt and Spec Rubber understand our business."

Mike Cecil Project Manager / Special Projects

“Our contractors love this Gasket, and the peace of mind it provides. The orange color helps keep the Restrained Gasket separated and makes inspection easy for crews and inspectors. I will only use your product on DIP projects. Thanks for explaining the benefits.”

Luke Fleischmann President

“At first, I didn't see the orange color making a difference, but my Foremen and inspectors love it. It helps separate gaskets and makes verification easy. Spec Rubber and you have elevated the industry. We’re proud to have our name attached to your excellent, made-in-USA products.”

Chris Haan Chief Construction Officer

“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.”

Sean Sutterer Vice President of Sales 

“The Barracuda® allows easy identification by crews and inspectors because of its bright orange color. Working with Matt Haan and the team at Spec Rubber has been excellent. Their support and quality products made in the USA keep us loyal and ensure job site success.”

Luke Fleischmann President

“Toruseal® Gasket simply does not leak. Its ability to catch and stop leak pathways is exceptional. I always insist that my suppliers provide the Toruseal® Gasket for all my flanged systems because the added security and peace of mind are worth the extra cost.”

Michael Yelachich Project Manager

“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.”

Michael Weller Vice President of Sales and Marketing

“The dual bulb design of the Toruseal® Gasket allows for an easy seal on imperfect flange faces. We have never had a leak or issue with it. I highly recommend this gasket to anyone looking for a reliable, high-quality solution for flange sealing needs.”
