You don't need metal braid for air pressures below 250psi. Metal braid reinforced hose is for hydraulic, or very high pressure air lines, the stuff that operates at 1,000psi and up.
Bike pump hoses are either 2 layers of rubber with a cloth mesh (braid) between them, or non-reinforced rubber with a small ID and thick wall to work up to 200psi or so. They sell rubber and vinyl tubing that will work at home depot. I have a reinforced clear hose that I bought at Home Depot and it has the advantage that I can visually confirm that air is flowing into the tire.
