Joint Tester 54"

The Cherne® Air-Loc® Joint Tester, 54" (part #9108) air-tests individual joints in installed 54" large-diameter pipe, so crews can verify each joint's integrity per ASTM C1103 without filling and testing the entire line. The tester isolates a single joint between its end elements, pressurizes the isolated annular space, and a short test confirms whether the joint holds.

Key Features

• Fast five-second test — determines joint integrity quickly, so crews can move joint-to-joint through the line.
• Tests with air or water — ready from the factory to test to 15 psi with air or 50 psi with water, no modifications needed.
• Pre-test before backfill — catch a leaking joint while it's still accessible and inexpensive to fix.
• Lightweight aluminum, sleeveless design — easier assembly and handling than heavier legacy joint testers.
• Independent, adjustable wheels — roll the tester through the pipeline from joint to joint.

Applications

Used by pipeline contractors and municipalities for joint-by-joint acceptance testing of large-diameter installed pre-cast concrete sewer and storm pipe per ASTM C1103.
