Discover Proflow's billet thermostat housings that eliminate leaks with O-ring seals. Choose from vertical or 360-degree swivel designs, complete with stainless hardware.
Proflow's billet thermostat housings not only look good, but they also get rid of leaky paper gaskets thanks to their O-ring seal design.
