Joint Tester 66"

The Cherne® Air-Loc® 66" Joint Tester (part #9128) air-tests individual joints in installed 66-inch large-diameter pipe, letting crews verify each joint’s integrity one at a time instead of testing the entire line. It isolates a single joint and pressurizes it so defects can be found and corrected before backfill, following the method described in ASTM C1103 for installed precast concrete pipe.

Key Features

• Individual joint testing — a short air test on each joint confirms integrity without filling or pressurizing the whole pipeline
• Air or water testing — ready to test with low-pressure air or water straight from the factory, with no modifications needed
• Lightweight sleeveless aluminum design — easier to handle and assemble in manholes and inside the pipe
• Quick-connect control panel — simple to install and remove, and its top-mounted position won’t interfere with laser alignment equipment
• Pre-test before backfill — catch leaking joints while they are still accessible and inexpensive to repair

Applications

Used by municipal sewer and storm-drain contractors for acceptance testing of large-diameter installed pipe, testing joint-by-joint per ASTM C1103 before the trench is backfilled.
