About Permalok

Permalok is a fabricator of steel piping utilizing the Permalok patented interlocking pipe joining system. The company eliminates the need for in-field welding and the down time associated with it. The Permalok connection is specifically designed for the trenchless excavation industry because it is flush with the interior and exterior surfaces of the pipe. Joint quality is further enhanced because the Permalok connection is consistently round, true and perpendicular to the pipe axis. Its unique stepped profile makes stabbing and aligning easy and quick. What's more, the Permalok design, combined with the use of a sealant such as RTV Silicone, will not leak even under considerable pressure.
