    Does anyone know what the three way valve is called on a p-valve and where one would get one. That is, the piece of plastic just on the inside of suit, with a side port about an inch long and the other two ports connecting to the hose going from catheter to the p-valve on the suit. Thx.

    Yes, this T (balanced mechanism inside I assume). Beyond a T, any specific item name or where one can purchase just this T.

    And check valves. If you want to get specific about it, low cracking pressure check valves.

    The T is just a regular T, the valves are attached to it by the tubing and are a separate entity.

    Just measure the inside diameter of the hose maybe 3/8 or 5/16 and google that size and plastic t piece. Should get tonnes of matches.

    Looks like something that could be made with drip irrigation parts.

    To be clear, you need more than a T fitting. You need valves.

    You can get the parts online or at many auto parts stores. The 3 way piece is a hose T piece. Common for vacuum lines, fish tanks, refrigerator drains, etc. The old school P valves used a PCV (positive crankcase ventilation) check valve off an older car. IME, the check valves tended to leak over time and needed frequent cleaning. The hoses can be fancy stuff or simple fuel line, use something that doesn't crush easily. Heat shrink is typically added over the connections.
