We’ve used dahl for 10 years because of reliability. If a valve installed out of sight starts leaking, it could be months before it’s noticed. That’s a disaster. dahl quality is so good after 10 years we haven’t seen a leaker. We run 60 trucks, so I figure dahl has saved us thousands of dollars in callbacks we didn’t have to make.  We’ll never switch.
