If the vacuum switch on a pellet stove starts throwing error codes or the orange sense hose won't hold a tight seal, the culprit is often the small aluminum fitting it connects to. The Enviro Aluminum Hose Barb (EF-019) replaces this worn or clogged connector, restoring a proper seal between the pressure switch hose and the appliance body or combustion fan housing.

Purpose

This hose barb links the orange pressure (vacuum) switch hose to either the appliance body or the combustion fan housing, allowing the switch to read draft pressure accurately.

Key Benefits

• Aluminum construction holds up to repeated heat cycling better than the deposits that clog the original fitting
• Restores a tight hose connection so the pressure switch reads correctly
• Genuine Enviro part built to the original fitment specification
• Straightforward swap for a component that commonly builds up residue over time

Other Notes

Unplug the appliance before removing the old hose barb, since access to the fitting can be tight depending on the model.

While replacing this hose barb, it's worth inspecting the pressure switch itself and the orange sense hose for cracking or blockage, since all three parts work together in the same draft-sensing circuit.
