Radiator Pressure Test Adaptor #31 for MG ZS HS MG4 EV

A radiator pressure test adaptor used to connect compatible pressure testing equipment to selected MG vehicles during cooling system checks. Adaptor #31 is intended for MG ZS, MG HS and MG4 EV applications where the correct cap fitting is needed for a proper seal and a reliable pressure reading.

Used in garages, workshops and home maintenance settings, this adaptor helps when diagnosing coolant leaks, pressure loss and general cooling system faults. It suits mechanics and DIY users carrying out vehicle servicing or fault finding on compatible MG models, especially when using a pressure tester across different vehicles and needing the right adaptor close to hand.

For regular testing work, having the correct adaptor in the kit saves time compared with trying unsuitable fittings that may not seal properly. This adaptor is for use with pressure test kits CT1585, CT3380 and CT5665, making it a practical match for users already working with those sets. Kept with the rest of your tester components, it helps keep the kit ready for repeated workshop use and makes it easier to cover more MG applications without guesswork.
