Cherne’s i-Series plugs are the most durable yet flexible plugs in the industry. All are bendable to 90° by simply removing the inflator valve. These multi-sized plugs will work in all types of pipe and have a wide expansion range, allowing you to keep fewer plugs on hand.
Lightweight Kevlar®-reinforced natural rubber adds superior product strength. For additional protection against damage caused by debris and sharp objects, the optional protective sleeve should be used.
Note: Larger size plugs feature a rupture disc that prevents over-inflation, safeguarding the user and protecting the plug from damage. The disc ruptures at 60% over the required inflation pressure. It is currently featured on plugs with sizes from 24 to 96" (stock #s 49899, 49901, 49903, 26305 and 26306).
