I've got an Outwell Dreamboat 16cm with the new FHF(flat high flow) valve; according to Outwell this means you can attach a pump to it to give the SIM a little more pressure without having to do it manually.. last time took quite a while... but I can't for the life of me figure out which pump adapter will fit with it. It looks to be about 2cm in diameter but none of the standard connectors work.
Has anyone else had any luck - and if so how did you solve it?
Follow-up to this - if anyone else has this question in the future. After talking to Outwell support(and trying this myself) - the recommendation is to hold the pump without any adapter up to the valve. I'm using an Outwell electric pump.
It isn't a tight fit but enough air passes into the mattress to inflate further and it appears that to prevent over inflation perhaps this is why it doesn't require a tight fitting adapter.
I have an Outwell mat and a Flextailgear Tiny Pump....after mucking around with the various connector adaptors that came included wit the pump I found that this combination seems to work quite well although you have to hold the pump to top-up the mat's inflation. The medium and large plastic adaptors both work when firmly mated with the silicone nozzle. Also both fit onto deflation port on pump.
