Hi,
Got one of these to fit tomorrow:
The guage is flat bottomed, same with seat in valve.
No washers have been supplied, except a little o-ring built into a spare platic sealing plug that can be fitted instead of the guage.
What should I do: buy a suitably sized o-ring, use a fibre washer or a little bit of potable water sealing gunk on the end (which worries me as it may block the guage port)?
I'm a bit thick when it comes to "iron" type joints...
Ta
Tim
