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

Cherne Industries, part of the Oatey Co. family of companies, today announced the addition of larger test plug sizes within its I-Series line of Test-Ball®, Muni-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”.

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.

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.
