TYGON® FLEXIBLE PLASTIC TUBING
TO TUBING SOLVENT SEALING

Published with permission from Saint-Gobain Performance Plastics Corporation


Permanent Tygon-to-Tygon bonds are easily made by solvent sealing; a useful process when joining lengths of tubing end-to-end or side-by-side, or in fabricating operations such as applying collars or flanges to tubing. The resulting bond is as strong as the Tygon material itself. In addition, a solvent seal eliminates the need for a fitting—solving any problems of leakage at the fitting-to-tubing connection or fitting material compatibility issues.

Basically, the bonding procedure consists of using a cyclohexanone solvent to solvate the areas to be joined, then placing them together in the desired position (i.e. end-to-end or side-by-side) and allowing them to dry.

The solvent can be applied by brush, dipping, wick dispenser, or in any number of appropriate ways. With larger bulkier pieces it may be necessary, before joining the two pieces, to make a second application of the solvent 4 to 6 hours after the first. Solvent sealing is as much an art as it is a science, and there is no rule about the amount of solvent to be used or whether a second application is necessary. We suggest performing several tests on tubing pieces of the same size and thickness—ensuring a strong, neat seal on the final piece.

A good method to join lengths of Tygon tubing end-to-end is to use a shorter “sleeve” of Tygon tubing with an inside diameter equivalent to the outside diameter of the tubing to be joined. After making sure that the ends of the tubing to be joined are cut square, dip them into the solvent, leaving them immersed long enough to allow the ends to soften (only a few seconds are required). Then, slip these two ends into the “sleeve” from opposite ends until they touch. After approximately 12 hours of drying time, the joint will have reached its full strength.

Cyclohexanone Solvent Handling Precautions:

Work only in a well-ventilated room, as fumes are hazardous.
Do not swallow, drink, or ingest the solvent. If ingestion occurs, drink plenty of water and seek immediate medical attention.
Protective gloves and eye protection are recommended. Should skin contact occur, wash affected area with soap and water immediately. Irrigate eyes thoroughly with water.
Keep away from heat, sparks, and flame. Store in a cool, dry place.
Work on a metal, porcelain, or glass surface which is impervious to attack by the solvent.

How to Splice Tygon® Tubing

Some specialized autoanalysis procedures require tubing IDs less than 0.51 mm. In these cases, order the Tygon® tubing with Luer lock fittings (95611-series) or make connections via the splicing method.

Bring together one end of a length of color-coded tubing (A) and one end of a length of extension tubing (B). (Both lengths of tubing should have the same ID and OD).
Center a 1" to 2" piece of larger tubing (C) over the ends of the two pieces to be joined (A and B). The short tubing piece should be of similar material and with an ID approximately equal to the OD of the tubing to be joined.
With the short piece (C) centered over the joint, apply solvent or sealant to the outside of tubing (B) and slide tubing (C) onto (B). Repeat the process for tubing (A) to join tubing permanently. If future tubing changes are necessary, then apply solvent or sealant only to tubing (B) and (C). Use a ketone-type solvent to splice Tygon® or Viton® tubing; an RTV adhesive for silicone tubing; and a tetrahydrofuran with PharMed® tubing.

Hi Dan
I have (successfully.?? ) made quenching tubes in the past, but they are rigid....also ,length is restricted to about 1 foot long. The cost is about $50 - $100 ( depending on how many holes you want) ...in materials, but they are easy to get from lab supply companies.
I don't have the one I made anymore because I sent it to someone to test it for me....and I never heard from them again....must have worked..lol..But if anyone is interested, I can maybe make a few more when I make my new ones...and yes, I will make a video on how to make them so everyone can make their own if they want....Cheers.

Hey Dan - FYI - though you likely know these already i suspect - Wittgas in Germany makes an HHO Flashback Arrestor  Model F53N HHO out of brass and stainless steel - made especially for HHO gas. This unit also has a temperature activated lockout mode in case of fire, the unit will lock off after 50 degrees C. 

http://www.wittgas.com/us/products/gas-safety-equipment/flashback-arrestors/for-pressure-regulators-outlet-points-inline/flashback-arrestor-f53nhho.html

I bought 2 for my motor home.

I understand though, that quenching tube is a must for any of these projects to move forward safely and into commercial use, though i'd personally want a couple of these Wittgas babies as well at key points in any HHO application.  If and when hho blows nothing will hold it back, it seems.

Best - Bill

Hi Bill, yes know them well they are very good, they also have flash arrest tester, believe it or not most in pure h2 biz like toyota , compressor maker fuel stations etc are not using flash arrestors as pure h2 will not spark in line.  I found it very interesting that that is occurring .

I how ever  insist on them , they also mak hho ones for use in welding etc
