Why is it so hard to get the most logically needed valve in the world...
an extra inline 3/8 x 3/8 shutoff valve to put between your expired copper
one and the standard flexible hoses going to sink faucet? Nothing can be
found locally, so i want to order online. The closest thing i can find is
plastic and im not sure is compatible with male and female metal standard
mating

By the way i found it doesnt help to force a non working shutoff valve
really tight, because the seals seem to crumble and jam up your faucet
filter. Of course the existing shutoff is half buried in a wall and
inaccesable. Thanks for pointers

Use a 3/8" FIPT x 3/8" FIPT ball valve, into each end thread a 3/8" MIPT x
3/8" copper gland fitting and insert it into your copper line. Often
one-piece fixes are hard to find, but assembling adapters will solve the
problem depending on what you are trying to achieve. If you are trying to do
something different than what I suggested, other types of adapters will do
the job.
