Connecting the Apex 1/4 flow sensor, how?

[OfficeReefer]

This is a silly but simple question. I don't see the typical 1/4 vinyl connections on the Apex 1/4 flow sensor. It says push to fit, however the 1/4" vinyl tubing does not want to fit through the caps into the sensor. I presumed they went over it and then tightened down the connection but it's almost like its expecting flexible tubing. Anyone know how this is connected or have one working they could share?

Haven't seen much video on this version, just the larger sizes. Any advice or thoughts welcome.

Thank you!

Here are the instructions Neptune indicates:

Strange. I saw the image, however my 1/4" RODI tubing does not wish to go through this. It's like they didn't finish the connector and left a 1mm plastic burr around the ID of the connector. Let me see if I can add an image this evening.

Here's what I was talking about. Notice the tubing will not go through the nut. It's like there's some burr on the edges preventing it through, even with force. Is this normal?

Ever figure this out?

Push it very, VERY hard.

It might seem like it will break and might but will eventually fit in there.
