Our Impact on the Industry
Test with the Best
Founded in 1953, Cherne Industries pioneered an inflatable device for stack testing and later expanded its pneumatic product line to cater to residential, commercial, industrial, and municipal systems. After its acquisition by Oatey in 1990, Cherne continued to prioritize system testing, maintenance, and repair, upholding a strong commitment to quality. Today, Cherne products are distributed globally serving contractors and engineers worldwide. Despite its growth, Cherne remains focused on delivering reliable and innovative equipment in the plumbing, waterworks and underground industries.
