Hi John,

        I have the metal valve but it uses the same O ring design.  Unless VC has a different metal one now.  I believe mine was from VC about 10 years ago.  I installed and it lasted this long.  But then the core warped where metal and plastic met.  I ordered a new core and new ring.  And then many more O Rings. 

Fingers crossed this one continues to work. 

At one time I saw vC had a special O Ring but I could not find it again.  I’m not a good web searcher I think it was about $8.00  The GW is .95 cents.  The Bus Depot was $3.75.

The metal valve seems very nice.  

I wish there was a heater core of better quality.  I think my new one is already starting to bend in the middle where the O Ring is clamped. 

        I was going to use gasket sealer this time but we waited to see if the thicker O Ring would work.  Fingers crossed.
