Barrier seals - Import export

Puddle Flanges ensure a watertight seal and radon barrier where pipes pass through concrete walls or slabs of any structure or building.

DLR manufactures high-temperature and high-pressure rubber seals and packers for the oil and gas (storage) industry for both wellhead or Christmas tree applications. We also manufacture vapour barrier materials that provide secondary sealing for large storage tanks to prevent vapour losses, along with packers for oil and gas applications. We combine our rubber compounding expertise with our precision rubber moulding capabilities to produce high-performance that withstand extremes of temperature and pressure to American Petroleum Institute (API) standards. And in an environment where safety is a paramount concern, our products can be relied upon.

The Locktainer 2020 bolt seal is one of the longest standing bolt seals worldwide, having been regularly updated with new design features to give unparalled tamper-resistance for all barrier seal applications, most notably shipping containers.
