Subject: Is there a copper washer on Silvia between the pump and the SS hose?
 

I bought a used 2010 Silvia and decided that before I start using it, I'll take it all apart and clean everything out. Someone had added a pressure gauge to it and since I saw teflon tape on the threads I decided to take it apart to check everything out. What I found was that inside the female side of the 1/8 BSPP stainless hose that sits between the OPV and the pump were 2 copper crush washers. They were badly jammed in there and the hose would not rotate properly in it's joint. I looked over all the part diagrams and this part is definitely not listed anywhere. For example, in this diagram: Click Here (www.pidsilvia.com) on the last page the elbow (Fig. 10) connects straight into the SS braided hose. Now since the hose is not connected to the original elbow but instead to the T fitting I figured the previous owner used this copper crush washers (not sure why 2 were in there). Then I went on searching for more information and I came across a few sites that would include two crush washers with the hose, for example:
Click Here (espressocare.com)

While others would not include it or even say anything about it: http://www.espressoparts.com/R_702

Then I found this: Click Here (www.1st-line.net)

The above is beyond confusing, that part number is not a standard Silvia part number as far as I can tell and $20 for a washer?

So which is it? Do these usually have a copper crush washer? If so, are these thing made out of gold and not copper ;) ?

Mine is mounted exactly as seen in the second picture (first row on the right) here: http://www.pidsilvia.com/pgaugehowtoT1.htm

If someone can shed some light on this that be great!

Thanks in advance,
Vadim
