EcoTek Spray Foam Posted: May 05, 2015 04:43 PM	Fusion AP - Manifold Sticking Recently i have noticed that the manifold shut-off valve on the "A" side has been getting stiff and harder to screw open and closed in comparison to the "B" side. What does everyone recommend? Does the manifold need rebuilding/ cleaning or is this a fairly typical occurrence. Thanks for your responses.

CJKEVIN Posted: May 07, 2015 05:28 PM	It is common for the A side to get gummed up or start leaking before the R side. When we have this problem we just replace the valve. I didn't know they made the parts to rebuild it. I also usually take the opportunity to remove the manifold from the hose and pull the small plugs in the manifold to make sure everything is clean and clear in there too.

Then back out the shutoff all the way and you will see the o-rings. We usually keep an extra rebuilt set so we can quickly swap them out as needed and get back to work. Don't mix them up though, we use red/blue electrical tape to identify which is which after the rebuild.

That's what I did after the third time replacing the A valve. I got my valves from swagelok.com valve: SS-42F2 about $80 each.
