Q: I have bought some of these from another maker and found that it does not fit the lockshield valve that comes with Drayton trv4 - it fits the TRV just not the valve. I'm on the hunt for ones that do.
I was about to buy yours but I notice someone else says the same about yours. What gives?
A: Ours fit the lockshield that comes with the TRV4 no problem at all.
Q: Will this fit with a Danfoss TRV?
A: As long as it is a 15mm compression one.
Q: Hi does the 8m pipe just slot in with no olive or anything just sealed with the comprsion from nut on the rad valve many thanks
A: Hi. Yes, that's correct.
Q: I've just bought 11 of these from you to convert 15mm Drayton TRV4s to 8mm. If I replace the 15mm olive, the nut no longer does up. Do these definitely work with 15mm TRV4s ?
A: Yes, as the nut tightens the reducer will "collapse" and grip the pipe. This will allow the nut to tighten fully.
Q: How does this work do they sit internally with in the valve ?
A: They replace the 15mm olive, so fit inside the 15mm compression fitting.
