Plugs SP......(We think slip plugs are a bad idea so we
don't offer them. Slip plugs ruin the fitting they are
glued into.  Use a length of pipe and a slip cap instead.
You will be able to cut the cap off later and attach a
line to the pipe with a coupling thus getting use of
the fitting again.) (if you want, however,we will special
order the slip plugs you want, just contact us and ask)
