The only ss braided hose I am aware of is the Parker hose it has a stainless steel internal braid over a rubber inner tube covered by a rubber and fabric outer cover. its available in
3/16", 5/16", 13/32" and 1/2" id commonly used on LP gas motor fuel (forklift and auto gas) applications. You have to field install the 2 piece reusable couplings and to my best knowledge they don't make a 1/4" inverted flare fitting for the regulator end so you would have to adapt. Very abrasion resistant but a determined critter can chew it given time.
