Stainless 1/2 in. Coupling for Speidel Plastic Fermenters

This attachement can be used to replace the spigot or the airlock on your Speidel plastic fermenter and give you a 1/2 in. MPT to the outside and a 1/2 in. FPT on the inside. This allows you to attach a variety of components on the inside and outside of your fermenter. This coupling uses the standard speidel lock ring and gasket.
