The perfect reducer to take a 3.5" duct down to 3". Exactly what I needed for my diesel heater setup.

This fits perfectly over the screw-on fresh air intake on 5Kw/8Kw Vevor heater. It allows me to connect to existing ducting on my boat.

Fits snuggly over the screw on intake grill on my vevor diesel heater. I used insulated 3" pipe to route fresh air through it.
