Description
The “Boston” valve is commonly used in inflatable boats and other inflatable devices. It’s a valve-within-a-valve system, featuring a one-way (“check”) valve that allows the cap to be safely removed while the packraft is inflated, allowing you to top up the air pressure without allowing any air to escape. The check valve can be unscrewed from the outer flange, creating a large opening for quickly inflating and deflating the packraft. Tough, flexible plastic loops hold the three parts together so the check valve and cap won’t get lost when they’re unscrewed.
This Boston valve has a heat sealable flange so it can be installed in TPU coated fabrics without using glue, as in the video above. If you’re installing this valve in a different material, use an adhesive that is compatible with both polyurethane and your material.
