Just the job, needed 10mm size to replace leaking valve(different make), best price in area & in stock locally

Bought it to replace defective existing TRV head but didn't fit the existing valve head so returned it & bought a Made4Trade one which did fit.

I bought the wrong valve but it looks very well constructed, I think the website need to describe the type of thread eg male female as my rad is old

This seems very well made and came with some good instructions also the setting is clearly displayed

Ok but dodgy threads spoilt it

I bought 2 as I wanted the 8mm converter. Unfortunately one was missing and I needed a refund.
Who is at fault, Pegler or Toolststion?
Its quality is bearable but the threads for attaching the TRV Head and the fitting to the radiator were coarse. The latter took extra ptfe and jointing compound to make it watertight on the second attempt.

Cheap but ?????

Easy to replace but really only needed the TRV head which Toolstation should offer separately.
