Adaptor M14 Short Reach (Requires TA212)

The M14 short reach compression test adaptor by Pico Technology is engineered for automotive technicians diagnosing engines with M14 x 1.25mm pitch short reach spark plug threads. This adaptor works with the WPS500X pressure transducer and TA212 compression hose (sold separately) to deliver accurate compression readings on modern engines with shorter spark plug wells, eliminating the need to remove all plugs.

The Pico standard compression hose (not supplied with individual adaptors) TA212 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 (1.0 mm pitch)
M10 Deep Reach  (1.0 mm pitch)
M12 Deep Reach  (1.25 mm pitch)
M14 Short Reach  (1.25 mm pitch)
M14 Deep Reach  (1.25 mm pitch)
M16 for Ford Triton style engines  (1.5 mm pitch)
M18 for older engines (1.5 mm pitch)

Please ensure that the adaptor you select is the same thread size and no longer than the tip of the 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.
