This inspection cap is designed specifically for boat stove installations, allowing easy access to the flue system for sweeping, inspection, and safely sealing off the stove during periods of non-use.
Manufactured from high-quality stainless steel with a durable matt black powder-coated finish, it blends seamlessly with other components in the system while offering long-lasting performance in marine environments.
Compatible with our twin wall insulated flue system, which features a simple push-fit joint—just place each piece on top of the last and push to connect. No sealants or fixings are required, making installation quick and easy.
Ideal for maintaining and managing your flue system safely and efficiently on board.
