Hi can you confirm if the koolance qd3 black fittings are the newer ones with the silver internal parts like pic 1,2,3 or older fully black inside and out like the last photo in the list cheers
Hi Tim,
These are the newer versions which have the silver internals. The photos with the coloured backgrounds are taken by us with stock that we have in the warehouse.
