316 Stainless Steel Exhaust Vent Tube with Bend Gasket

316 Stainless Steel Exhaust Vent Tube with Bend Gasket for boat Air Heater Systems 316 stainless steel marine exhaust vent elbow designed for boat air-heating and exhaust systems. Corrosion-resistant 316 construction, integrated gasket for leak-free sealing, available in 22mm and 24mm (custom sizes on request). Engineered for harsh marine environments and easy on-board installation. Product Description This 316 stainless steel exhaust vent elbow is built for marine air-heater and exhaust applications. The polished 316 body provides strong resistance to salt spray and seawater corrosion, ensuring long service life in demanding onboard environments. The unit includes a purpose-made gasket to create a tight seal between the flange and hull or bulkhead, preventing leakage and backflow. The elbow bend is sized to simplify routing of heater exhaust lines and to accommodate both flexible and rigid tubing. Available in standard vent hole sizes of 22mm and 24mm, the unit can also be customized to meet specific diameter or length requirements. The product is ideal for boaters and shipyards seeking a robust, marine-grade exhaust connector for air heaters, steam or hot-gas exhaust lines. Key Feature Marine-grade 316 stainless steel — excellent salt-water and corrosion resistance. Integrated gasket & flange — reliable sealing to prevent exhaust or steam leakage. Standard & custom sizes — 22mm and 24mm standard; custom diameters available. Boat air-heater optimized bend — angle and profile designed for marine heater exhaust routing. Durable & easy to install — supplied with bolt holes for secure mounting. Quality checked — inspected before shipment; recommended maintenance intervals provided.

Prepare the mounting surface: cut the hole, deburr edges and ensure the flange surface is clean and flat. Place the gasket between the flange and hull/bulkhead and align bolt holes. Insert bolts and tighten in a cross (diagonal) pattern to ensure even compression of the gasket. After installation, perform a short operational check and inspect for leaks. Re-check bolt torque after first operating cycle. Recommended maintenance: inspect gasket and mounting bolts every 6–12 months (shorter interval in heavy salt environments). Compatibility & customization Compatible with most boat air-heaters and small marine exhaust systems. Custom hole diameters, longer tube lengths, and alternate surface finishes (polish, passivation, plating) available on request. OEM orders and private-label packaging supported for bulk quantities. Packaging & warranty Packaged in protective foam single carton; waterproof or export crates available for bulk shipping. 12-month limited warranty against manufacturing defects (excludes misuse, accidental damage, or corrosion due to improper maintenance). Each unit is inspected for dimensional and seal integrity before shipment. FAQ Q: Which vent hole sizes are available?A: Standard sizes are 22mm and 24mm. Custom diameters are available—please specify when ordering. Q: Is this suitable for marine (saltwater) environments?A: Yes. The body is made of 316 stainless steel, which offers excellent resistance to salt spray and corrosion. Regular inspection and maintenance are still recommended. Q: How do I ensure a leak-free installation?A: Use the supplied gasket, align flange holes, and tighten bolts in a cross pattern. Re-check torque after the first operation cycle. Q: What gasket material is used and what is its temperature rating?A: Standard gasket is a heat-resistant rubber compound suitable for typical heater exhaust temperatures. For high-temperature applications, request a high-temperature gasket option when ordering. Q: Do you support OEM or bulk orders?A: Yes — OEM marking, custom packaging, and bulk pricing are available.
