Product Number: 31405370
When a cylinder leakage test reveals compromised sealing, accurate diagnosis depends on having the correct spark plug adaptor to form a reliable, leak-free connection between the tester and the combustion chamber. Without the right adaptor, test results can be inconsistent, wasting diagnostic time and leading to incorrect conclusions about engine condition.
The Sykes Pickavant 31405370 is an M14 Quick Connect spark plug adaptor designed specifically for use with Sykes Pickavant cylinder leakage tester kits. The quick-connect fitting allows the adaptor to be attached and detached rapidly from the tester's airline, enabling the technician to move between cylinders efficiently during a full engine leakage assessment.
This adaptor carries an M14 thread, the standard spark plug thread size found across a wide range of petrol and diesel engines. It is a designated replacement or supplementary component for two specific Sykes Pickavant kits: the 31370000 Combined Petrol and Diesel Cylinder Leakage Tester Kit and the 31370500 Petrol Only Cylinder Leakage Tester Kit. No technical specifications beyond thread size and compatibility are stated in the source data.
As a direct Sykes Pickavant accessory part, this adaptor ensures correct fitment and compatibility with the leakage tester kits it is designed to support, maintaining the integrity of the diagnostic process.
