Designed for stack testing of drain, waste, and vent plumbing systems, Clean-Seal® plugs thread into a standard test tee. The bladder is inflated and then water is introduced into the pipe. Upon test completion, deflate the bladder; water travels down the pipe, eliminating test water backsplash.
• Works in both plastic and cast-iron test tees
• Natural rubber body provides a leak-free seal
• High-impact ABS threads for maximum durability
• Removable/replaceable tire inflation valve fitting
