What is the pipe type on the Nautilus Panel - is it exclusive to Nautilus?

I am going for the easy answer on this. Is the pipe and valves used on the Nautilus control panel made by Nautilus, or can it be purchased else where? If so, can someone provide me a link to where?

Standard PEX tubing and connections. I like "shark bite" connectors, but you will need to purchase a special crimping tool (which also removes them) in order to make the connection. Linked below is the kit I purchased from Amazon.

I am asking about these fittings. I should have been more clear.
