H Bypass Fitting for Heater w/Aftermarket Ac and Heat - H Pipe

H Bypass fitting 5/8 for all Coyote swaps and other applications. This is so coolant flows continuously through the cooling system when using aftermarket AC from Vintage Air, Classic, and many others. 

Pairs great with our Heater hose kit and hot water fittings. Waterneck bleeder screw kit is also highly recommended to complete the full circuit of cleaning up and simplifying your cooling system in your swap. 

This H-pipe bypass fitting meets Ford Motorsports' recommendation for a heater control valve bypass to maintain continuous coolant flow through the right-hand cylinder bank on Coyote engines.
