Rated 1 out of 5 by from Not fit for purpose. Brought two of these as could not source elsewhere during lockdown. First one split in two places with appropriate torque, second one leaked despite appropriate PTFE, and unable to tighten as normal due to tenancy to split! Chinese steel?

Rated 5 out of 5 by from Handy extensions Handy problem solvers. They can be a bit tricky to seal but i find Loctite 55 works well

Rated 5 out of 5 by from Exactly what i needed Bought these for changing radiators. My old radiator was 550mm wide and the new one is 600 mm so the 2 extenders made up the difference.

Rated 1 out of 5 by from Cheaply made I purchased one of these to bridge the gap in a new rad after replacing my older type which was 30 mm wider . The extension snapped while tightening it with a radiator valve Allen key by hand . I couldn’t believe how weak it was . It left the thread inside the rad . I managed to remove it . But I certainly wouldn’t purchase another
