Right on Richard! And make certain you use the brass sleeves that slide into the tubing. Get them snug by hand then maybe a 1/2 turn or so and they shouldn't leak. If you're replacing a pushon with a compression fitting remember you have to compress the sleeve so it'll be a bit harder than when re-tightening an existing fitting. It's only 120psi max and lower in some cases like the bladder etc.
