Cherne’s 72-120 in. Test-Ball Plug was carefully developed with an optimized design that offers improved performance and safety. Accommodating a back pressure of up to 6 psi, the plug weighs 850 pounds and is 152 inches long. It is made from tough, tear-resistant natural rubber and features ¾ inch eyebolts that provide superior holding strength. A field-replaceable pressure relief valve prevents over-inflation, and an aluminum end plate minimizes rust and corrosion.

“When jobsite conditions call for a test plug of this size, we know safety and performance are of the utmost importance,” says Cassandra Alverson, Product Manager at Cherne. “That’s why we’ve engineered the world’s largest test plug with the same quality control and manufacturing standards that Cherne is known for around the world.”
