Cherne® Air-Loc® Joint Tester 72"

The Cherne® Air-Loc® Joint Tester 72 in. (part #9138) tests individual pipe joints in 72 in. diameter sewer lines. It straddles a single joint, seals against the pipe wall on both sides, and pressurizes only that joint — the low-pressure testing approach used for installed pre-cast concrete pipe per ASTM C1103.

Key Features

• Tests joints individually — every joint gets its own pass/fail, so leaks are located precisely the first time.
• Air or water testing — ready for either medium with no modifications.
• Rapid test cycles — each joint verifies in seconds, keeping large-diameter acceptance testing moving.
• Pre-backfill verification — prove joints tight before the trench closes, while repairs are still simple.

Applications

Standard equipment for municipal acceptance testing of new 72 in. gravity sewer and storm installations, and for pinpointing leaking joints during inspection or rehabilitation of existing large-diameter lines.
