Brass hose barb 3/8″ MNPT x 1/2″ barb “long stem” 90°
(BRSS_05_427)
This fitting is hand-made to conform to the dimensions of the original elbow used by Universal on the outlet of the water pump and the inlet to the thermostat housing on late model engines.
In these locations, the elbows needed longer stems so that the hose from the water pump would clear the top of the aft housing and the hose from the thermostat housing would clear the side of the head.
