Old-type fist stage valve housings
with (G 1/8”) threads are equipped
with nylon gaskets seats.
It is not normally necessary to
change these seats during service.
However, if the seats are subjected
to a great deal of over-tightening,
the interior orfices can be reduced
in diameter, significantly reducing
flow and performance. Compare
installed gasket orifices with a new
gasket, and replace as necessary.
Gaskets must also be replaced
after a long time acid-bath.
