What! A non-Briegel product? Yes, but it's here just to prove the Briegel style fittings are still being made. This one is insulated like the Red Throat. It differs from its cousin in that the fitting itself is all one metal piece (Don't ask me how they do that.) and the yellow insert is put in from the top and can be removed. The original Red Throat was placed inside before the pieces were fastened together, so it couldn't be removed without breaking something.
