About Us

Since 1993, CSD Sealing Systems has been a trusted provider of high-performance sealing solutions, protecting critical infrastructure from fire, water, gas, smoke and EMP.

We specialise in technically advanced cable and pipe penetration seals, including the globally proven NOFIRNO® and RISE® systems. Our products are engineered for the world’s most demanding environments, whether you’re operating in power, marine, offshore, nuclear, utilities, or data infrastructure.

From day one, we’ve believed that safety starts at the seal. That belief continues to drive our innovation, our partnerships and our commitment to helping clients deliver safer, more resilient sites.

With over three decades of experience, our team combines deep technical knowledge with industry insight to solve complex challenges on land and at sea. We’ve supported thousands of projects, including major naval vessels, nuclear facilities, national utility networks and renewable power infrastructure.

We’re not just suppliers, we’re technical partners. Our clients trust us to deliver products that perform, services that deliver peace of mind, and solutions that last.

Our mission is to continue setting the standard for penetration sealing across the industries that power, connect and protect society. As we expand our reach and product range, our focus remains the same: delivering performance you can trust in environments where failure is not an option.
