Whilst not wishing to get a bad reputation from my first post, I really do have that problem on a heating circuit I'm installing. I've got a Female 1½" to Male parallel 1" (brass) adapter and the male end is too short for the female part of the next coupling.
Should I
a.) Use two aramid washers;
b.) Use an aramid washer on top of a rubber washer;
c.) Use a brass or stainless or other type of washer as a spacer, with jointing compound or liquid ptfe on the threads;
d.) Saw the female part shorter;
or e.) Find a different way of doing it?
The application is for an unvented underfloor heating system normally running at max. 40°C. and the joint is only likely to be undone in the event of the pump being replaced, or because it's leaking ...
Thanks for your advice.
