Query: Crush washers are too fragile

This product ships with no installation instructions. You'll probably tighten the banjo bolt down until the whole piece is somewhat stable. That's where you will go wrong. Gas spews all over the place and those delicate little plastic washers are warped and wont seal anymore. Too bad they dont throw in another pair. So you postpone your project until Ace Hardware opens so you can buy some copper crush washers and try to salvage the 15 bucks you're already in the hole; and just to ensure you make progress on you spend some extra cash on a 5/8-20 hose barb connection in case you have to scrap everything and go back to the basics. It's a shame, because the metal part is actually built better than I expected. I was really afraid it was chromed plastic. Count on this piece costing you another 9 bucks plus time and frustration and budget accordingly.
