micro fuel line fittings

I recently searched the internet for micro fuel line fittings. Not something that you'll find just anywhere. I bought some barbed Tee fittings and caps for 1/16" tubing from McMaster-Carr.

Packages shown in photos below

I'm hoping that these fittings will help with the management of balloon fuel-cell (NOT PRESSURE-BLADDER) fuel-delivery applications.

Thanks Roddie, exactly what I have been searching for for exactly my unpressurized balloon tanks, with no result ..

The smallest things I so far found in fish tank accessory shops were still too large in my COX 010...09 world..

That’s a good find Roddie, You have a knack for seeing outside the box for useful modeling items Thumbs Up

…. Learning to make and use balloon tanks has been really helpful to me on getting consistent runs ….. A lot of wiggle room too on how much fuel you want to carry…

The McMaster-Carr warehouse is just 9 miles away from me.
I've orders many things from them and have saved on shipping when I pick them up at the counter.
The warehouse is in an industrial area, so you'll have to drive around to find it.
But once you been there, it's easy to find again.

Just watch out for the semi-trucks driving around doing drop-offs and pick-ups in that industrial park.

I've been amazed at the availability of things here in the Houston area, some Amazon stuff is same day! I do miss having a Fastenal on the way home from work... I've only ordered from McMaster-Carr twice since getting out of the USCG. Hey, Mike, the package is on the way! Sent you an email...

Here are those tiny Tee-fittings applied to a pair of very small balloon-type fuel cells.

Close-up view of zip-tie closure example.. simple, compact and lightweight.

Simply "snip-off" the zip-tie using nail-clippers to renew the balloon.. and re-use the internal components and Tee-fitting.

Incidentally; the fuel-line I show here was sourced from Amazon.. and has an ID of .062" (1.5mm) and an OD of 3/32" (2.4mm)

Comparison to Dubro Sm. size silicone tubing..
