Robco has been manufacturing and distributing gaskets for more than 100 years and during this time has expanded its Gasket Division to manufacture an impressive array of grades and types of cut gaskets and sheet materials in all available sealing materials on the market today. Robco will custom cut gaskets to your specifications using the most efficient production equipment possible. Our flashcutters, waterjet, punches and travelling heads produced just under 1.8 million gaskets in the trailing 12 months.

Our RedOps technical team will use advanced modelling software to calculate the required bolt torque suitable for your applications and will review and recommend and if requested, train on best installation practices with your teams.

Always on the lookout for the latest innovations in gasket sheeting, Robco will keep introducing new materials to suit even the most difficult applications. Your Robco representative will review your requirements and offer the best solution to maximize your operations and lower your costs.
