Test Ball Plugs Are Designed For Pressure Testing And Blocking Of Residential DWV Plumbing Systems, And Repair Maintenance And Installation Of Municipal Infrastructure.
Test Ball Plugs are durable, rugged and effective in any type of pipe to seal both round and out-of-round pipe for long lasting reliability. Made of natural rubber for excellent expansion and memory. Air-Loc plugs can also be used to block flow by simply plugging the fill and read-back ports. Long test-ball plugs are designed for waste stack testing from floor drain to sewer pipe, and are long enough to seal away vertical riser and sewer run. Some models include field-repairable rupture disc technology to eliminate over-inflation risk. Available back pressures are 6, 7.5, 8.7, 9, 10, 11, 13, and 17 PSI. Feet of head ranges between 14 and 40 feet. Sizes vary per model.
