    SPA PP700 regulator bellville washers

    The gun was leaking around the regulator when filled to full pressure, which seems to be a common issue with these.
    So I took it apart to clean up any surfaces and try to stop the leak.
    The problem is, I didnt take any notes of how the bellville washers were stacked
    Does anyone on here have any hints?
    I'm guessing this varies depending on the power setting of the specific market?

    Thanks to both of you!
    Probably differs on different pressure settings, but all info may be useful.

    Great! My gun is still in parts, and if I remember correctly, it has 10 washers, not 12.
    But great info, and a place to start.
    Lesson learned, sometimes it really pays to notice how things are put together..

    Thanks!
    I've gotten some replies on a facebook forum, which verifies what the last post as a std UK stack.
    This is described as a 12fpe stack: ))((()))((

    Bringing this back to the surface again, as I finally have som motivation to work on airguns again...

    The standard UK (6fpe?) stack seems to be:

    A suggested 12fpe stack is:
    ))((()))((

    Can anyone suggest a stack that would work in between 6 and 12 fpe?
    If I remember correctly there was 12 belleville washers in mine, which was bought second hand and could be a swedish 10joule version.
    Too many airguns!
