          Brass construction provides long service life. Popular quick-connects
          provide reliable, fast and positive connections and quick disconnections
          for regulators, hoses, and torches on welding equipment. Instant connections
          speed up setup and teardown. Color coded for gas service and additional
          safety: fuel gas–red; oxygen/inert–green. Non-interchangeable fuel gas
          and oxygen connectors prevent accidental gas mixing. Spring-loaded
