The GReddy PRO/SPEC adapter converts a 5/8 NPT threaded connection to a 10 PRO/SPEC connection for interfacing dissimilar fittings. It lets you adapt a 5/8 NPT port to the PRO/SPEC 10 connection standard used in compatible plumbing runs, providing a direct changeover point to join different thread types without extensive rework of existing lines.
