Cherne Industries Expands Line of Robotically Manufactured I-Series Test Plugs

March 9, 2022

Test plugs sized up to 48 inches are now available, featuring the safety and durability of the innovative I-Series technology


Cherne Industries, part of the Oatey Co. family of companies, announced the addition of larger test plug sizes within its I-Series line of Test-BallMuni-Ball and Air-Loc pipe plugs. I-Series plugs are built using an innovative robotic manufacturing system that delivers industry-leading quality, consistency and durability. The new I-Series Test-Ball, Muni-Ball and Air-Loc plugs are available as large as 24-48 inches.

In addition, I-Series plugs feature corrosion-resistant aluminum base plates with laser-etched identifiers, replacing the use of raised rubber markings that eventually wear away with usage. The plugs are lightweight, short and flexible, while offering superior back pressure to accommodate the range of plug sizes offered. Protective sleeves are also available for the full range of I-Series plugs, helping further preserve the plugs for extended use. Cherne’s I-Series Test Plugs provide improved performance and safety through their optimized design. Manufactured robotically, each plug’s natural rubber core is mechanically bonded to its aluminum end plate, ensuring precision and consistency while eliminating failures that can result from chemical-bonding processes.
