I have a gas grill that goes through an O-ring about once a year.

If you look closely at this picture you can see an O-ring where the
connector screws into the regulator.

About once a year this O-ring get chewed up and begins to leak. I've
bought the O-ring at a hardware store but I'm wondering if there is
someplace else I should be getting them from.

Is there a special material for gas grill O-rings?

Nothing special that I'm aware of, but why are they going bad? *I've
been using propane appliances for decades and have never had to
replace one.

Check the mating surface on the tank. *Could be a burr or grit or
something causing the ring to get eaten up. *They should last years
under normal use.

This is the first grill I've ever had a problem with.

It's a BBQ Grillware from Lowes. The first one started leaking after
about three years. I replaced and it started leaking a year later, now
it's a year later and it's leaking again.

I replaced it last night but I may have bought the wrong size because
it won't seal. I only brought the connector in with me, now I've taken
the regulator off and I'm going to take them both to the store.

One more try at a 40 cent O-ring. Next will be a $36 replacement
regulator/connector combination.
