The Cherne Story
In 1953, Cherne Industries created an innovative inflatable device for stack testing. Cherne’s pneumatic product offering expanded to include testing, maintenance and repair equipment for residential, commercial, industrial and municipal systems. Acquired by Oatey Co. in 1990, Cherne products are relied on by residential and commercial contractors and industrial and municipal engineers worldwide.
In 2024, Oatey acquired Lansas B.V. in the Netherlands, further cementing our position as the global leader in pipe plugs and testing. As our pipe plug business has grown, its focus remains constant – providing customers the most reliable and innovative testing, maintenance and repair equipment in the plumbing, waterworks and underground industries.
