Joint Tester 108"

The Cherne® Air-Loc® Joint Tester, 108 in. (part #9208) air-tests individual joints in installed 108 in. large-diameter pipe, so crews can verify joint integrity per ASTM C1103 without filling an entire line. It isolates one joint at a time, meaning a leak is pinpointed to the exact joint instead of condemning a whole run of pipe.

Key Features

• Tests with air or water — factory-ready for testing to 15 psi air or 50 psi water with no modifications required
• Fast joint verification — a five-second test determines joint integrity, keeping acceptance testing moving on long runs
• Sleeveless, lightweight aluminum design — easier handling and assembly inside the pipe and through manhole access
• Pre-test before backfill — verify joints while they are still exposed and inexpensive to repair
• Joint-by-joint isolation — identifies exactly which joint leaks rather than averaging results across a full segment

Applications

Municipalities and heavy-civil 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 trunk lines where full-line testing is impractical.
