Precise Compression Adaptоr For PDS500X M12x1.25mm

Product Description

Тhis optional bi-metal compression adaptor is designed to have the minimum possible deflection and damping effects when pressure changes in a wide range.
The adaptor’s extremely small internal volume helps maintain the volume internal of the combustion chamber during the compression stroke.
In this way, the total error of the measured pressure at top dead center is significantly reduced.

The PDS500G optional precise compression adaptor is used directly when the spark plug thread is M12x1.25mm.
For the other spark plug threads, the precise compression adaptor must be used with the appropriate additional adaptor to perform engine compression tests with the PDS500G.

The precise compression adaptor has an integrated 17mm cut out for spanner wrench size of 17mm.

Note: This adaptоr is optional and it is not included in the PDS500G Pressure Transducer Kit!
