Product Details
✓TRUE 316 MARINE STEEL: Our thru hull exhaust fitting is crafted from 316 stainless steel — the same alloy used in yacht hardware. This ensures no rust streaks on your wall, siding or boat hull for years, even in salt air and exhaust acid conditions
✓DOUBLE-WALL HEAT SHIELD: Our double-wall design keeps the outer surface touch-safe even with 300°F+ exhaust flowing through. This ensures your garage wall, siding, insulated garage door or greenhouse panel never melts or scorches, giving you a fire-safe install you can trust
✓EVERYTHING INCLUDED: Includes 2 thru wall fittings, 4 heat-resistant silicone gaskets, 2 metal gaskets, and nuts/bolts — no extra trip to the hardware store. Designed for a straightforward setup that mounts in about 10 minutes with a 2-1/4 inch hole saw
✓ONE KIT, MORE PLACES: Fits 22mm/24mm inner-diameter exhaust hose from most diesel parking heaters. Use it in your garage, shed, RV, van, boat hull, greenhouse or tent. Note: the straight design is not intended for adding a muffler after the wall pass-through — choose the Bend version when you need an angled outlet
✓CHOOSE YOUR METHOD: Straight and Bend interface options suit different installation angles. Pick Straight for direct wall exits, or Bend for tight spaces where the exhaust must turn immediately after passing through
