Enviro 1/4 in. Spring Pin for Pellet Stoves (50-1701)

If the pressure switch on a pellet stove is throwing intermittent faults, or the orange hose at the back of the unit looks cracked or caked with residue where it attaches, the hose barb it connects to is often the cause. The Enviro Aluminum Hose Barb (part 50-1701) replaces this fitting in compatible Enviro pellet appliances.

Purpose

This hose barb links the orange pressure (vacuum) hose to either the appliance body or the combustion fan housing, allowing the pressure switch to read draft accurately. Buildup on the barb over time can prevent it from sealing properly, leading to false switch readings.

Key Benefits

• Restores an accurate seal between the hose and pressure switch circuit
• Supports correct combustion airflow readings for safe operation
• Direct-fit replacement for the original Enviro fitting
• Addresses buildup and corrosion issues common to this component

Other Notes

Unplug the appliance before attempting removal or installation, as access to this fitting can be tight depending on the model.

While replacing this hose barb, inspect the pressure switch itself and the orange vacuum hose for cracking or hardening, since both commonly wear alongside this part.
