Question:
I have a 2015 keystone Raptor 300MP needing a new black tank valve system. I can’t figure out the difference between spigot to spigot or the spigot to hub for which one I’ll need. Can you explain the difference between the two. As well as if you have any idea on what I should get. Thanks!

Hi Matthew; a spigot end slides into the sewer pipe and a hub end fits over the sewer pipe. If you take a look at what you have now it will probably be obvious once you understand how it works. If both ends of the valve slide into the connecting pipes you need the spigot to spigot # 34466N4BB72GM. If one end goes over and one end goes in then the Spigot to Hub # 34466N4AB72GMA is the correct valve.
