The GA3 Gauge Adaptor is a high-pressure hydraulic fitting designed to provide a convenient gauge connection point within a hydraulic system. Featuring a 1/4 in. NPT gauge port and a maximum working pressure of 10,000 psi, this adaptor allows operators to monitor hydraulic pressure during lifting, tensioning, testing, and bolting applications.
Commonly used with hydraulic pumps, cylinders, torque wrenches, rebar couplers, anchor bolt testing equipment, and custom hydraulic tool assemblies, the GA3 enables quick installation of pressure gauges without modifying the primary hydraulic circuit. By providing accurate pressure readings, operators can verify system performance, monitor applied loads, and improve operational safety.

🔹 Rental Insight
The GA4 Gauge Adaptor is often overlooked but plays a critical role in hydraulic testing and monitoring applications. Contractors frequently include this adaptor in anchor bolt testing packages, rebar grip systems, and custom hydraulic toolboxes because it enables pressure gauges to be connected quickly and safely. When paired with hydraulic cylinders and calibrated gauges, it helps operators monitor system performance and verify applied loads during testing operations.
The applied load depends on project specifications and anchor design requirements.
They can. Hydraulic Rentals can supply complete flat jack rental packages including hoses, couplers, and pressure gauges.
You need a grip size that matches your rebar diameter and grade.
Yes. Flat jacks are commonly used for lifting bridge components during bearing replacement.
