Hi: I saw an old post where people had extra o-rings they would ship. I have a Profitec 500 and the oring on the vacuum relief valve disintegrated. The ones one Amazon aren't available anytime soon. If someone has extras lying around and would be willing to ship them I'd be grateful - I can pay via Venmo or Paypal.

I believe the right size is: 007 Silicone O-Ring, 70A Durometer, Red, 5/32" ID, 9/32" OD, 1/16" Width

Thanks.

Nick

Seems to me I bought gaskets for my pro500 at cafe parts. https://www.cafeparts.com/Home

You can find rings at Lowes for about $3 for a pack of 5.

Nick,

These are the ones I ordered for my Synchronika (but the size matches up with the ones you need): https://www.mcmaster.com/9396K12
If you click that page and it tells you to log in to view details, just enter the 9396K12 in the search bar and it should take you there. Pack of 25 for a bit over $5.

McMaster-Carr is pretty quick with their shipping and seeing as they are in GA (vs me being in Houston), it would probably be just as quick ordering direct from them... Like Ken (Plinyyounger) said, you might be able to find a replacement at lowe's, at least as a temporary fix (most of the o-rings I've found at my local Lowe's were not silicone and probably won't hold up to the heat for long.)

Hope that helps!
Josh
