I have been going into my parts reg (all non serviceable parts), and I was looking at the LP stem and rubber seat. The stem is bent. While the seat surface has the imprint of the (volcano), i notice that the seat falls out quite easily, and the other side is still flat and non grooved, and quite clean.
Is it an acceptable form to simply turn the seat upside down and use the unused side. Could this be done as a field expedient fix, or should the used seats be discarded at all times.
