Cherne Air-Loc® Joint Tester 84"

The Cherne® Air-Loc® Joint Tester 84 in. (part #9168) is a joint-isolation tester for 84 in. diameter sewer pipe. It seals against the pipe wall on both sides of a single joint and pressurizes just that annular space, proving each joint individually — the approach described in ASTM C1103 for testing installed pre-cast concrete pipe joints.

Key Features

• Single-joint isolation — identifies exactly which joint leaks instead of failing an entire line segment.
• Air or water test media — ready for either method straight from the factory.
• Seconds per joint — fast test cycles keep large-diameter acceptance testing productive.
• Pre-backfill capability — confirm joint integrity before the trench is closed, when corrections cost the least.

Applications

Used on municipal and heavy-civil projects for acceptance testing of newly laid 84 in. gravity sewer, storm, and culvert pipe, and for verifying individual joints during rehabilitation work.
