The Pico standard compression hose must be used in conjunction with the appropriate adaptor for carrying out Engine Compression tests with the WPS500X.
Adaptors are available for the following spark plug thread sizes
M10 short reach
M10 deep reach
M12 deep reach
M14 short reach
M14 deep reach
M16 for Ford triton style engines

Please ensure that the adaptor you select is the same thread size and no longer than the tip of spark plug you are replacing. While using a shorter adaptor than the spark plug you are replacing may produce results that are slightly low using one that is longer may damage your engine.
