3.5" Hose Adapter – Diesel Heater Exterior Vent Port

This 3D-printed 3.5-inch hose adapter is designed specifically to fit the Muddy River Outdoors heater port. If you want to run a larger hose from your diesel heater, this adapter is what you need — it steps up from the heater port opening to accommodate a standard 3.5" ducting hose.

• Fits Muddy River Outdoors heater port only — not a universal fit
• Use this adapter when running a larger 3.5" hose from your heater
• Locking retention ring for a secure, rattle-free connection
• Lightweight and durable 3D-printed construction
• Matte black finish blends with most van interiors and exteriors
