Automotive exhaust fitting designed to channel diesel heater exhaust away from hulls and reduce heat transfer. Owners of vans, motorhomes and boats gain peace of mind as nearby panels stay cooler and diesel smell lessens. Is the autozen Thru Hull Exhaust Fitting the right upgrade for your heater installation?
⚡ At a Glance
- • Heat Resistance: Increased pipe gap reduces heat transfer, keeping surrounding surfaces cooler
- • Best for: Owners of vans, motorhomes, trucks and boats using 24mm heater hoses
- • Not ideal for: Installations that require fittings for hoses with different inner diameters
316 stainless steel thru hull exhaust fitting sized for 24mm inner diameter hoses. Polished chrome finish with included screws and gaskets for straightforward installation.
Reduced heat transfer - with increased gap between pipes
Design increases the space between exhaust pipes to interrupt conductive heat flow, lowering surface temperature around the hull or panel. That gap acts as passive insulation rather than relying on added materials.
Surrounding areas remain noticeably cooler, reducing risk of heat damage and helping eliminate hot spots near heater outlets.
Longer service life - with 316 stainless steel construction
316 stainless steel provides greater toughness and wear resistance compared with 304 stainless steel, with improved resistance to corrosion in moist or salty environments. Polishing and chrome finish add a protective surface layer.
Corrosion resistance and robust construction mean fewer replacements and dependable performance in marine and automotive settings.
Straightforward installation - with included screws and gaskets
Packaging contains one thru hull fitting plus three screws and three large gaskets to form a sealed connection. Accurate sizing for a 24mm inner diameter hose reduces alignment and sealing issues.
Quick fit-up saves time during heater installation or replacement, giving a reliable seal and consistent exhaust routing.

❓ Frequently Asked Questions
Q: Is this fitting compatible with my heater hose?
A: Designed specifically for hoses with a 24mm inner diameter, so compatibility requires a matching hose size.
Q: What material is used and how durable is it?
A: Constructed from 316 stainless steel, which is tougher and more wear-resistant than 304 stainless steel and resists rust in harsh environments.
Q: Does it help with heat and diesel smell inside a vehicle or boat?
A: Yes, the increased gap between pipes reduces heat transfer and user reports note cooler surrounding areas and reduced diesel smell.
🏆 Our Verdict
Ideal for van, motorhome and boat owners fitting 24mm diesel heater hoses who want a durable, heat-managing exhaust outlet. High-quality 316 stainless steel construction and a gap-based insulation design are the key strengths, with a polished chrome finish and installation kit included. While cost may be a consideration, long-term corrosion resistance and reliable fit deliver value over time.
