Mystery Pneumatics Piece?

So I am building my pneumatics parts for my team, and I am missing the piece that connects the pressure Relief Valve to the Union tee. Can someone identify it? The URL to the parts list that it should have came in. Thank you! It should be the piece at the top left corner of the product image.

The piece you are referring to is this.

Make sure you understand where all the pieces have to go.

Also, it is helpful to have lots of metal parts where it connects to the compressor. It helps dissipate the heat. If you put any plastic parts there, some may melt.

…not to mention fail inspection. Some parts are required to have hard (metal) plumbing to the compressor.

Welcome to CD.

It is great that you are asking these questions this early in the build season. You will find that many people here are very willing to help you. Unfortunately, there may be errors in your system that you do not realize are errors so you will not ask about them and you may get hung up once you get to your first tournament. You are in Toronto, surrounded by many teams with a lot of experience and who are typically very willing to help rookies like yourself. It would be best to ask one of them to look over your system. There is no substitute for actually laying eyes on it.

Best of luck in the upcoming season.
