Kamoer STP pump soft tube adapter

[kris2001]

Hi
For my kamoer STP pump, I accidentally bought this tubing adapter that seems like half inch.

I need an adapter that's for the quarter inch soft tube to hard quarter inch tubing that's used in rodi...

What do I get... Here's what I have and tubing I wanna use to extend the line for pump.

This is what I have going on. It is not pretty but it works. It looks like I have the same adapters that you have. I used 1/4 bulkhead fittings to connect the ro tubing to the barb adapters.
