Unlike competitive products, Cherne’s High Pressure Plug has the rubber and metal bonded, eliminating fears of separation or rolling off resulting from high back pressures. The plugs are multi-size - 6 plugs will cover pipe sizes from 4″ to 32″. They have an optimized design using steel, aramid and natural rubber to ensure longevity and robust construction.
Water must be used to pressurize these plugs due to high working pressure. Use #278188 or #278198 pumps for this.
