Replacement silicone seal for Rancilio Silvia over pressure valve (OPV). Also comes with the outer O-ring seal for the threaded fitting (not pictured). 

The seal in these OPV's deteriorate over time as they're subjected to both pressure and heat very often. A deteriorated seal will lead to pressure instability at the group head during extraction as water that should be held back by the seal in the valve will flow past through any compromised part of the seal. 

 If you're servicing one of these machines, it's always good to replace the OPV seal while you're at it. We do this as a standard part of a service on all Rancilio Silvia machines that come through the door, or any Rancilio machine with the same boiler/OPV configuration.

**A quick disclaimer**

I love free things, we all do, and that's why I offer free postage on some of my listings. I make it a habit to send your orders through the post office directly, rather than dropping it into a Post Box where they can sometimes get stuck in the mail bag. Please understand however that if you choose the free shipping option, there is no tracking number. If you opt for free postage and your order doesn't arrive, I can't be held liable. It's rare, but it can happen.

I take photos of all orders before I ship them out and am happy to send you yours as proof.

To avoid this, I recommend using either the standard trackable mail option or even the Express post option if you need your order in a hurry. They might not be free, but they're trackable.

Thanks for your support and understanding,
