The Brass SAE 45° Flare Short Nut secures a 45° flared tube end to a matching flare fitting, creating a reusable, leak-tight, metal-to-metal seal on air, fuel, refrigeration, and low-pressure fluid lines. Forged from CA377 brass for strength and corrosion resistance, the short-body (short rod) style keeps the connection compact where space is tight.
