I-Series Test-Ball® plugs are designed for line acceptance testing and temporary pipe blocking. Each plug supports 15 psi (1 bar) maximum back pressure and inflates to 45 psi (3 bar). The series is built with mechanical bonding between premium natural rubber and end plates for durability. Larger diameters across the I-Series also incorporate an engineered pressure relief valve to improve safety.

Back-pressure note: back-pressure capability varies by pipe diameter; use the chart on the page to confirm PSI at your diameter (e.g., 300–600 mm plug supports 27/25/22/19/15 psi at 300/400/450/530/600 mm).
