Cherne Rupture Disc Technology

Cherne Rupture Disc Technology is now available for large diameter Test-Ball and Muni-Ball plugs.

Designed to prevent plug over-inflation, the patented rupture disc both safeguards the user and protects the pipe plug from damage. Combine Cherne’s improved large diameter pipe plugs, which now have cross-biased cording, with the company’s new Rupture Disc Technology and you get a safer, longer-lasting product. Rupture Discs increase plug life by preventing “non-visible” damage to cording and they won’t burst until well over stated. The discs can be replaced in the field improving user safety to over-inflation. 800.843.7584,
