Water/Airtight Systems

Using our unique radio frequency welding methods, London Bridge Trading Company manufactures an assortment of backpacks and bags, which are watertight and airtight. All of these products are certified by NAVSEA for use by special forces in submersible operations. An oral inflation valve allows for inflation/deflation of these products, and all are constructed with a waterproof heavy-duty zipper closure. Our watertight/airtight systems protect items held on the inside but are also used to contain items which may give off dangerous fumes, such as an outboard motor. A small selection of these items are pictured on this page. You can also browse all water/airtight equipment at our online store.
