Loop End Cap
- A2080020: Manifold Loop End Cap
These allow you to cap off a loop of the manifold if it will not be used.
TruFLOW Supply/Return Ball Valves
- A2631250: TruFLOW Supply/Return Ball Valves (box of 2)
These allow you to quickly shut-off the supply and return sides of the manifold. These valves are R32 thread x R32 thread. The supply and return ends of the manifold is R32.
TruFLOW Supply/Return Adapters
- TruFLOW Supply/Return Adapters
These allow you to connect the manifold to your supply and return lines. The supply and return end of the manifold is R32 thread. Choose an R32 adapter that will connect the manifold to your desired application.
- A3010522: Thermal Actuator (4 Wire)
If you want to use your manifold to heat multiple zones, you can purchase return side actuators that work along side thermostats. The actuators act as zone valves to allow you to use one manifold to control the temperature in different rooms independently.
