We put together a kit with everything you need to replace a “Boston” pvc inflation valve. This is a typical valve for inflatable boats and air mattresses. It has two different unscrew-able stops. The larger stop releases air when removed whereas the smaller (inside) stop has a one-way valve and allows inflation when removed. We also have a how-to video here: https://youtu.be/ig0AaJiQJ58
Kit includes Boston pvc inflation valve, syringe full of HH-66 pvc glue, and clear pvc material (4” x 4”)
