Joint Tester 30"

The Cherne® Air-Loc® Joint Tester, 30 in. (part #9048) air-tests individual joints in installed 30 in. pipe, letting crews verify joint integrity per ASTM C1103 without plugging and filling the entire line. Each joint is isolated and tested on its own, so a failure points to the exact joint that needs attention.

Key Features

• Tests with air or water — factory-ready for testing to 15 psi air or 50 psi water, no modifications needed
• Fast joint verification — a five-second test determines joint integrity, so acceptance testing keeps pace with the crew
• Sleeveless, lightweight aluminum design — allows easy assembly in manholes and confined access points
• Pre-test before backfill — check joints while the trench is open, when repairs are fastest and cheapest
• Joint-by-joint isolation — pinpoints the leaking joint instead of condemning a whole segment of pipe

Applications

Municipal sewer authorities and pipeline contractors use Air-Loc® joint testers for acceptance testing of installed large-diameter precast concrete pipe joints per ASTM C1103 on storm and sanitary sewer projects.
