It's supposed to be unfreezable. I think the cup seal is a standard part.
What part is damaged? If it's leaking, there are only three things that can leak, the cup seal, the valve body o-rings, and having the valve screw too tight. The valve screw is the screw that holds the valve body in place, it is found under the gripframe.
Huge obnoxious sig line!!!
