The cone washer sold by itself was a challenge to find, but I did finally track it down. Most places only sell an entire swivel fitting with the cone washer in it. No one wants to deal with a penny type item held in inventory.
Flair-It is a brand of fittings that offers their swivel seals separate from the fittings as replacements and they are potable water rated. They call it "SANTOPRENE SWIVEL SEAL 1/2"" and it uses part number 06435 for a single seal and part number 16425 for a pack of 10.
I used to buy these on Amazon for $0.99 for a pack of 10 as an add on item. You had to buy $25 worth of something and they would then ship the pack of 10 with that shipment. Shipping these costs more then the seal itself, or use to.
Here is the Amazon link, they are now today offered for $9.94 for a pack of 10. Just they really do not say its 10 but the part number is correct. Here is the link
Here is what came when I ordered them.
The price is now sort of nuts even with Prime shipping. I have no good reason why they cost that much. You can buy single ones, but these retailer's will charge freight.
RV Upgrades, $0.43 each (1 seal) https://www.rvupgradestore.com/Sanip...-p/88-9292.htm
Dyers RV, $0.41 each, 1 seal, https://www.dyersonline.com/flair-it...vel-seals.html
I have bought from them both and had good transactions. Just the check the freight as it may cost more then the Amazon.
There are other options that you may find locally. You go to the local pluming supply store, Lowes, Home Depot etc. and buy a 1/2" PEX swivel fitting, plastic or brass, and then pull the cone washer out of it. While I said plastic, sometimes the lower cost plastic fitting is a pack of 5 fittings which can be more then the Amazon cost. If you can find individual fittings, then 2 fittings may be cheaper bought locally in plastic or brass.
Like this one from Lowes, $3.48 for one, 0r $6.96 + tax
Here is another post on these cone washers and the hunt to find them which may help on the fittings I bought to get the cone washer out of them.
I myself have never been able to buy a faucet that the cone washer came with the faucet. Even if it was an RV faucet. The new faucet just had the 1/2" male NPT ends and it was up to you to hook it up. It seems that is not true on all brands since Thekid710 found a faucet with them included. Point being, when you go to the store or wherever you buy the faucet, check to see what is included so you do not have to make a second trip back to get the cone washers.
Hope this helps
