Replacing the quick-release regulator on an old 1998 Weber grill

The Weber Genesis grills from 1998 use a quick-release style regulator, which looks similar to an air compress quick disconnect fitting. Tanks that use these adaptors no longer exist, are hard to fill, and are reaching their end of life in terms of safety.

By purchasing a the newer style QCC 21” regulator and a 1/8” to 3/4” flare adaptor, these grills can be converted to use the more widely available newer style tanks.

Attach the new regulator to the 3/8” flare nut. There is no need to use pipe tape on this end, the flare nut will make a tight seal:
