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-Ball, Muni-Ball and Air-Loc pipe plugs. I-Series plugs are built using a robotic manufacturing system that delivers quality, consistency and durability, Cherne notes.

 The new I-Series plugs are available as large as 24-48” and 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, the company adds.
