With our partnership with Sealweld, we are the world leader in emergency valve sealing. Our techniques and procedures allow technicians to inject cleaner and sealant while the valve is in-line and under pressure. We focus on manufacturing ‘temporary’ sealants that can be flushed out after the work is complete, allowing the operator to cycle the valve again if necessary.

Our emergency sealants are specially designed to provide a reliable seal when required and can be used in most makes and types of lubricated valves. With our expertise, products and procedures refined over decades of field applications, you can expect to successfully seal 98% of all valve leaks.
