Product Overview

Darco Southern continues to be a premier manufacturer of industrial gasket products since 1976. Darco Southern provides high temperature thermal and protective sealing solutions globally. Our gasket products are used a variety of applications including commercial and industrial boilers and furnaces, chemical processing, petroleum refining, power generation, metal processing and more.

There are a number of variables that need to be considered to ensure proper gasket selection. Our vast array of available materials and coatings combined with our vertically integrated, in-house product design, engineering and manufacturing capabilities, allow us to design, prototype and produce the optimal solution, in the minimal time frame. Although we offer “standard” gasket product configurations, we welcome the opportunity to develop a custom gasket around your design requirements. In collaborate with your team, we review construction and dimensional requirements to create a tailored gasket to solve your specific design challenge. Ask us about the Darco Southern 4D Process!
