Expand your valve tester to include EF86
The Orange Valve tester MKII Expansion Module C plugs into your existing Orange Valve tester MKII (purchased separately), enabling it to test EF86 valves. As a plug-in device, it can be easily removed for when you need to test other valve types.
Keep your EF86 valve powered devices in tip-top order, with the Orange Valve Tester MKII Expansion Module C.
