Title: Clear Tygon tubing: is it always inflexible?
Post by: Rudemouthsky on October 18, 2014, 03:35:09 PM
I got this stuff from Motowheels and it's just teh suck, and I'll never get it from them again. No matter how carefully I cut it with a sharp razor, there's an inner barrier that peels. The worst part is how damn inflexible it is. Even 90 degree bends are impossible and once it's kinked a couple times, the liner inside delaminates and looks like crap. Did I just get a bad batch? Here's a few shots;

Tygon 2375 from MW:

(http://i1008.photobucket.com/albums/af202/johnnyblaze19761/20141018_161307_zpssnp1vmlt.jpg) (http://s1008.photobucket.com/user/johnnyblaze19761/media/20141018_161307_zpssnp1vmlt.jpg.html)

On the contrary a full 180 deg bend is no problem for the OE stuff:

Now, the way I want to route it may be out of the question, what do you think?

(http://i1008.photobucket.com/albums/af202/johnnyblaze19761/20141018_165333_zpsyramggz0.jpg) (http://s1008.photobucket.com/user/johnnyblaze19761/media/20141018_165333_zpsyramggz0.jpg.html)

Should I give the Tygon another shot? In any case I'll get it from McMaster Carr next time.

Maybe try warming it with a hair dryer/heat gun?

I did try the heat gun..I was a bit leery of over doing it though because of how sensitive the liner seems to be. McMaster-Carr classifies this stuff as "very flexible" so I thought perhaps I just received a bad batch from MW. I did find a "bend radius" stat that said "2 inches" which doesn't seem "very flexible" to me at all.

I think I figured it out actually...what Motowheels sells is the 2375 which is standard "chemical resistant", and has a hardness description of "firm". The SE-200 is the "ultra chemical resistant", and scores "soft" under the hardness description. I'll order some of that and report back.

If I am doing 90 deg with tygon I use an external spring over it

I have found it is all crap , stick to OE ( but must say did not know there are different hardness )

Well I'm certainly not one to always pick function over form but in this case I like the OE black hose too..but my reservoirs are billet and the window is useless for monitoring fluid health.

I'll wait till tomorrow evening to place the order if anyone wants to go in on it? It's only sold in 2 foot lengths but I'll cut whatever length you need and pick up the tab for shipping it to you in the lower 48. Here's the product page for it:

Is that 2375 Tygon?  I've got some 90+° bends in mine and no problems. I buy it from us plastic.com.  Here's an old pic of my 1216 Bandit:

Another thing I discovered through Tygon themselves is that the 2375 is NOT approved for constant exposure to ethylene glycol. Only the ultra (SE-200) is. Nothing nice to say about Motowheels, so...I'll just throw this $12 in the trash and order from MMC. :)

I have used Tygon for years processing liquid fueled rockets and associated equipment, both flight and GSE. I have it on three bikes and have not had any problems as described by the OP.

Anyone interested in using it needs to do a bit of research because there are several flavors. You can Wikipedia it, Google it, or go to the manufacturer web site. My experience is that the easiest way to buy it for bike use is to refer to http://www.kurveygirl.com/shop/index.php?cPath=106&osCsid=g4scs4kmafqc7604eu3ber1bn2. (http://www.kurveygirl.com/shop/index.php?cPath=106&osCsid=g4scs4kmafqc7604eu3ber1bn2.)  Look for Tygon Tubing in the pull down menu on the left side.

She has done the research and lists the basics particulars for each type she carries.

I'm not jonesing for clear tubing that bad, lol.

I might get more 2375 as well as the SE-200 just to confirm that the 2375 isn't suitable or that I just got a bad batch. Because both Kurvey Gurl and Motowheels are calling the *ultra* chemical resistant stuff 2375, and SE-200 is the only *ultra*.
Title: Re: Clear Tygon tubing: is it always inflexible?

US Plastics also lists Tygon 2375 as ultra chemical resistant, as does a scientific supply catalog at my lab.

Great thread

amazing to see the bends you are getting ...but like I said maybe I have been buying the crap stuff

gotta say with the spring externally it looks very industrial ( it is on my sons Ninja  so getting a pic will be doubtful )

Post by: Rudemouthsky on October 19, 2014, 03:49:02 PM
I ordered stainless spring clamps for 3/8" hose if anyone needs some, minimum packs of 50 which is way too many for me to use. The plated OE clamps can be pretty cheesy. Just pay for the stamp.

When I'm not on my phone I'll try to post the technical document I referred to that ID'd the 2375 as standard "chemical resistant. There's a link right on the McMaster product page.

Kurvey Girl data sheets show the 2375 as having a minimum bend radius of 3/4".
This is backed up by data at McMaster-Carr.

Kurvey Girl shows the SE-200 as having a minimum bend radius of 2", and noting that it's a 2-piece construction, having an FEP liner.

What does Ethylene Glycol resistance have to do with using it for brake fluid?

McMaster-Carr data sheet says both 2375 ans SE-200 have excellent resistance to Ethylene Glycol.
http://www.mcmaster.com/#8354kac/=u88h0g (http://www.mcmaster.com/#8354kac/=u88h0g)

SE-200 is 6519T, and 2375 is 5103K.

Good question. Apparently my associates degree in Chemistry from the University of Google made me just knowledgeable enough to be dangerous...I naively conflated ethylene glycol with DIethylene glycol.

Neither myself or Ute are getting "bendability" from what we've both assumed is the 2375. Duchead has a different experience. Maybe he actually has the SE-200. Or maybe Ute and I got some bunk tubing. What I have def has a liner though, and both MMC and KG only designate the SE 200 as having this.

So far I've only succeded in littering the internetz with even more confusing and potential (dis)(mis) information.

Well I didn't expect this...

(http://i1008.photobucket.com/albums/af202/johnnyblaze19761/20141021_144435_zps5wbahni_edit_1413920897059_zpsgh0vorpz.jpg) (http://s1008.photobucket.com/user/johnnyblaze19761/media/20141021_144435_zps5wbahni_edit_1413920897059_zpsgh0vorpz.jpg.html)

It's the SE-200 that is inflexible, and the 2375 arrived in its own individually wrapped Saint-Gobain packaging as ULTRA, while the SE-200 did not have that distinction.

(http://i1008.photobucket.com/albums/af202/johnnyblaze19761/20141021_144546_zpsgm0a6llb.jpg) (http://s1008.photobucket.com/user/johnnyblaze19761/media/20141021_144546_zpsgm0a6llb.jpg.html)

And as you can see, it's the 2375 that is nice and flexible.

(http://i1008.photobucket.com/albums/af202/johnnyblaze19761/20141021_144435_zps5wbahni_edit_1413921196543_zpsp3kqqfmd.jpg) (http://s1008.photobucket.com/user/johnnyblaze19761/media/20141021_144435_zps5wbahni_edit_1413921196543_zpsp3kqqfmd.jpg.html)

So apparently MMC has the features of the 2 flip flopped on their website. It seems that the 2375 is the ultra chemical resistant tubing with "very flexible" and "soft" characteristics, while the SE 200 is "hard" and regular "flexible" /"(not ultra) chemical resistant". I suppose what Motowheels sent me was actually the SE200?

There's yet another formulation known as 2075/MMC #5046K13 that is also supposedly an "ultra", which is a 2 week back order @ $3.20 per ft/1 ft minimum orders but I was too impatient to wait for it.

The 2375 is $1.70 per ft/ 5 ft minimum and I'd suggest anyone interested should jump on that because I think MMC is selling it at the wrong (too low) price, with the SE200 actually being the inferior one that *should* be that price instead of $3.39/2 ft minimum order.

Bottom line, it seems that 2375 is the winner, and both MMC and Motowheels have things mixed up. I bet Motowheels bought their tubing from MMC which would explain it!

If anyone wants a foot of 2375 plus stainless spring clamps, come at me Bro. I'll beat everyone's price just to break even on this little experiment.  :)

Cheers
