Re: [APD] Re: problem with tank/regulator seal
There are fiberous paper and nylon washers available. The
nylon ones compress permanently and should be replaced
whenever you open the fitting. However, in a pinch, you cna
get one to work more than once.
The firber washers don't compress as much and don't deform,
making it a little harder to get a good seal but easier to
reuse the washer.
The washers are cheap.
