Plugs close the ends of any fittings or nipples and can prevent debris from entering the plumbing system. Constructed of lead-free brass, brass flare fittings are ideal for gasoline, grease, natural gas, and refrigeration/ac applications. The brass construction makes this fitting corrosion-resistant and is able to be used indoors and outdoors. Flare fittings can be used in conjunction with aluminum tubing, brass pipe, copper tubing & steel hydraulic tubing.
