Rebuilding cylinder heads requires many different operations. From disassembly  to cleaning to crack detection and repair, all steps are critical in completing the job properly and efficiently. Pressure testing plates are used to accurately identify leaks ensuring the integrity of the entire cylinder head by pinpointing potential leak points.

Innovative Machine & Supply utilizes its extensive catalog of head shim designs to manufacture Pressure Testing Plates for most any application required by our customers. PTPs are laser cut from ¼ mild steel and come with a 1/16 neoprene gasket to seal between the plate and the cylinder head.

Leak detection:  Quick and easy method of leak detection.

Quality control:  They enable thorough testing of newly repaired cylinder heads, verifying their ability to withstand operating pressures and identifying any flaws.

Efficiency:  Pressure testing plates streamline the process by saving time and effort compared to testing the entire head at one time.

Additional Block Off Plates:  If you need any additional plates for end or side ports, we can design and manufacture to your specs and needs.
