Managed to get the Goretex valve out of my NSP DC, then broke the cap off it when putting it back in 
The UK NSP distributor doesn't stock these, anyone know where I can order one from? Thanks.
You could maybe try Shapers - I'm sure I've seen Goretex valves & parts on their website but they may only sell in bulk lots. Worth a check though
Thanks for the info, turns out Shapers do have them but the cost of Intl postage is over twice the price of the vent!
NSP, if you guys read this forum, anyone in Europe stock spares?
Well, I never heard from NSP, but Shapers were able to help me out. Thanks guys, great service.
now just gotta be gentle fitting that vent!
