Pressure Tester – CHT1240
The Winona Van Norman CHT1240 Pressure Tester is designed to quickly and accurately detect leaks, cracks, and other defects in cylinder heads before they are returned to service. By pressurizing the cylinder head and submerging it in a heated water tank, the CHT1240 allows operators to visually identify escaping air bubbles, making it easy to pinpoint even small leaks or hidden cracks that could lead to engine failure.
Pressure testing is an essential step in the engine rebuilding process, ensuring cylinder heads maintain proper sealing, cooling system integrity, and overall performance. The CHT1240 provides fast, accurate, and repeatable testing to verify repair quality, reduce costly comebacks, and improve diagnostic confidence. Built for professional engine rebuilding operations, it is an indispensable tool for shops committed to delivering reliable, high-quality engine rebuilds.
