I-Series Test-Ball Plug with Rupture Disc 20" - 40" Nominal Size
Cherne’s I-Series plugs were designed to meet the needs of both the US and International markets in terms of size and expansion range. These I-Series plugs have full body cording for added durability.
Features
Cherne Test-Balls are now available with patented Rupture Disc Technology. This feature prevents over inflation of the pneumatic plug. Rupture Disc Technology also prevents damage to cording. Damaged cording is an unseen condition that compromises plug performance.
