Automotive and marine exhaust hardware that routes diesel heater fumes safely while lowering external temperatures. Owners of vans, boats and trucks gain cooler hull surfaces and reduced diesel smell for more comfortable use. Is the DRSUMLF Thru Hull Exhaust Skin Fitting durable and straightforward to fit for 24mm heater hoses?
⚡ At a Glance
- • Heat Resistance: Increased pipe gap helps keep surrounding surfaces cool and reduces fumes entering the cabin
- • Best for: Owners using 24mm inner-diameter diesel heater hoses such as Planar, Eberspacher, Webasto and similar
- • Not ideal for: Hoses with an inner diameter other than 24mm
316 stainless steel construction offers superior toughness and wear resistance compared with 304. A deliberately enlarged gap between pipes provides heat insulation while a polished finish helps the fitting blend with the hull.
Lower surface temperatures – With increased pipe gap for heat insulation
An enlarged clearance between the inner and outer pipes creates an insulating air layer that slows heat transfer from exhaust gases to the surrounding skin. The gap reduces conduction and lowers the temperature felt at the hull or vehicle surface.
Surrounding areas stay cool to the touch and are less likely to suffer heat damage. Cabin ingress of diesel smell is reduced, improving comfort during heater operation.
Long-lasting corrosion resistance – With 316 stainless steel construction
316 stainless steel is specified for greater toughness and wear resistance compared with 304, offering enhanced resistance to corrosion in damp or marine conditions. Polished surface treatment aids longevity by reducing surface contamination.
Fitting life increases in salty or wet environments, cutting the need for frequent replacements. Maintenance demands are lower thanks to the rust-resistant material choice.
Neat, practical installation – With polished angled fitting and included fixings
Angled configuration and surface polishing create a flush, low-profile appearance that blends with thru-hull locations. Packaging includes one skin fitting, three screws and three large gaskets, with an installation video available for guidance.
Fitment for standard 24mm inner-diameter hoses is straightforward using supplied hardware. The ready-to-mount kit reduces preparation time and helps ensure a watertight seal when installed correctly.

❓ Frequently Asked Questions
Q: Will this fit my diesel parking heater hose?
A: Compatibility is for hoses with a 24mm inner diameter and for Chinese Diesel Parking heaters var4, Planar, Eberspacher and Webasto as listed.
Q: Will the fitting rust in marine use?
A: Construction uses 316 stainless steel, which the manufacturer states is tougher and more wear-resistant than 304 and will not rust.
Q: Will it reduce heat and diesel smell near the hull?
A: The enlarged gap between pipes acts as heat insulation, helping the surrounding area stay cool to the touch and reducing diesel smell entering the vehicle or cabin.
