The VJLD (Vacuum Joint Leak Detector) is an advanced tool engineered for the swift and precise detection of leaks in tube-to-tubesheet joints. Ideal for heat exchanger manufacturers and retubing operations, this tool ensures the reliability and integrity of tube joints expanded or welded.

Key Features:

Effective Leak Detection:
The VJLD seals the interior of the tube and the tubesheet face, creating a vacuum at the joint. Any loss of vacuum indicates a leak, facilitating immediate detection and repair.

Flexible and Adaptable:
Equipped with interchangeable manifolds and seal sets, the VJLD can accommodate tubes with outer diameters from 3/8” to 2½” (9.5mm to 63.5mm), making it versatile for various applications.

Lightweight and User-Friendly:
Weighing less than 2.7 lbs. (1.2 kg) with a ¾ inch manifold, the VJLD is lightweight and easy to handle, ensuring user convenience.

Operates on Standard Air Supplies:
The tool functions with standard compressed air supplies, operating at pressures between 40 and 125 psi (2.8 to 8.6 bar), ensuring compatibility with existing systems.


The VJLD is perfect for:
Heat exchanger manufacturing
Retubing projects
Maintenance and repair of tube-to-tubesheet joints in various equipment
