Early faucets were also supplied with 1/2" male pipe threads and this kit will allow use of the original fittings as it provides a way to go from the 1/2" female pipe threads on the replacement faucets back to the original 1/2" male pipe threads by ordering a set of the Female fittings listed below in may we also suggest.

(1) 11" Blue rigid extension hose with 1/2" male NPT fittings on each end
(1) 11" Red rigid extension hose with 1/2" male NPT fittings on each end

Rigid hoses can be trimmed as needed depending on installation requirements. Make sure that cuts to the hoses are perpendicular to the hose to help prevent leaks.
