Joint Tester 42"

The Cherne® Air-Loc® 42" Joint Tester (part #9088) tests individual pipe joints in installed 42-inch large-diameter pipe. Rather than pressurizing an entire run, it isolates one joint at a time and applies a short air or water test, so each joint can be accepted — or repaired — before backfill, per the ASTM C1103 method for installed precast concrete pipe.

Key Features

• Joint-by-joint verification — quickly determines the integrity of each joint without testing the full line
• Tests with air or water — arrives ready to test either way, no modifications required
• Sleeveless aluminum construction — lightweight design assembles easily in manholes
• Quick-connect control panel — installs and removes in moments; top mounting keeps it clear of pipeline lasers
• Pre-backfill testing — identify defective joints while the trench is still open

Applications

Municipal and utility contractors use Air-Loc® joint testers for pipeline acceptance testing of large-diameter sewer and storm-drain installations per ASTM C1103.
