Default Need some help finding the right compression tube fittings.

I'm looking to upgrade all my plumbing to silicone tubing with quick disconnects.

My immersion chiller and heat exchanger coils are 3/8" OD, 1/4" ID copper tubing so I'm going to plumb with 3/8" ID silicone tubing.

Here are the parts I've picked out at McMaster-Carr:

Silicone Tubing (3/8" ID, 5/8" OD): 51135K37
3/8" Hose Barb to 3/8" Socket: 6739K62 (QD sockets for the tubing)
3/8" Male NPTF to 3/8" Plug: 6739K57 (QD plug for MLT and HLT ball valves)
1/2" Male NPTF to 3/8 Plug: 6739K59 (QD plug for pumps)
3/8" Female NPTF to 3/8 Plug: 6537K12 (QD plug for MLT return pipe)

The only puzzle left is figuring out how to fix a QD plug to the chiller and heat exchanger tubing. I'd really prefer a compression fitting because I don't have a propane torch. It looks like this one (50915K224) will fit the bill but I'm not sure. Can anyone confirm this? Is there a better fitting or solution to get QD plugs onto the ends of the copper coils?

Reason: Fixed typo

A propape tourch set up can be found for 10 bucks if you shop around, sweating copper is shockingly easy.

I can not get MMC to load for some reason, but you will want a 3/8OD to 3/8 NPT compression fitting, male or fremale depending on your application.

Something like this.
