Joint Tester 90"

The Cherne® Air-Loc® 90" Joint Tester (part #9178) air-tests individual joints in installed 90-inch large-diameter pipe. It isolates and pressurizes one joint at a time, allowing crews to confirm the integrity of every joint in a large-bore line before backfill, following ASTM C1103 for installed precast concrete pipe.

Key Features

• Individual joint testing — a short test on each joint verifies integrity without filling or pressurizing the entire pipeline
• Air or water testing — ready to test with low-pressure air or water straight from the factory
• Lightweight sleeveless aluminum design — sized for very large pipe yet built for practical assembly on site
• Quick-connect control panel — simple to install and remove, with top mounting that won’t interfere with laser equipment
• Pre-test before backfill — find and fix leaking joints while they are still accessible

Applications

Built for pipeline acceptance testing on the largest sewer, storm-drain, and culvert installations, where testing joint-by-joint per ASTM C1103 is far more practical than full-line testing.
