The Heater Bulkhead Push-On 2 Port by Billet Specialties is an essential cooling system component for custom and street rod builders who demand precision-engineered manifold solutions. This bulkhead fitting bridges heater hoses to engine block ports, managing coolant flow in hot rod restorations and modified engines where original cooling passages require modernization. Whether you're running a fuel-injected small-block conversion or a vintage engine rebuild, this push-on design eliminates the need for threaded fittings and complex adapters, streamlining your cooling system layout.

Built to Billet Specialties' exacting standards, the Heater Bulkhead Push-On 2 Port features a dual-port design that accommodates standard heater hose connections without ferrules or compression rings. The push-on fitting method ensures a secure, leak-free seal when properly installed on compatible port sizes, reducing assembly time and minimizing potential coolant loss during high-temperature operation. This compact unit measures 5.3 x 1.65 x 6.05 inches and weighs just 0.29 lbs, making it ideal for tight engine bay installations where space is limited and weight matters.

The two-port configuration supports independent heater core circuits or secondary cooling needs, offering flexibility in complex cooling designs. Compatible with standard automotive heater hose sizes, the Billet Specialties bulkhead integrates seamlessly into both modern fuel-injection conversions and classic engine bay layouts, delivering the reliability and fit quality that separates professional restorations from amateur builds.
