  Air-Loc® Manhole Testers provide the most efficient, accurate and cost-effective method of testing new, existing and rehabilitated manholes, per ASTM C 1244.   Vacuum testing identifies infiltration and exfiltration problems by creating a vacuum in a manhole and then monitoring a gauge for vacuum loss. Less expensive and faster than water testing, the Air-Loc® manhole tester's remote-inflation and monitoring system keeps users away from the “danger zone."

Bladder-Style Air-Loc® Head Assembly Features:
Seals the inside diameter of the manhole at frame or cone
Supported by a durable aluminum brace
Push-pin rod design for easy depth adjustment
