Quenching Tubes and Ceramic Arrestors
As Many holes as possible around 3/8" OD or 14"OD or bigger
Multibore / Multi Lumen Tube Works as Stated Tested
and the holes need to be smaller than .015 no bigger than .025 OD..Polyurethane, However, Clear Vinyl tubing is also a possibility. It looks like it's moiled around set of 5 "multi-lumen" bored tubes inside which could be like FEP/LDPE white tubing.
Stanley Meyers Quenching disk works like stated. Tested
Now we need to find ceramic ones and also start the real tests!
.025" around 60 microns and .0015 is about 30 microns 0.015" (stans) = 381 micron
Stanley A Meyer Quenching Tube Fittings
How did Stanley A Meyer Connect his Quenching tube of different diameters to the cell and injection systems ?
We Know he may have used flexible multi bore Fiber optic tube
in Sizes nominal OD 1/4" =hose inside diameter 0.22 to 0.25" = 4 AN = 8mm
Summary today we need
1 Brand options part number for the attach an fitting
so far we need 1/4 OD fitting 6mm
note we can go bigger but this is close to original 3/8 optional
Stainless Steel Swagelok Tube Fitting, Male Connector, 1/4 in. Tube OD x 1/4 in. Male NPT
note check it has ferrule in kit
part Part No. SS-400-1-4
6mm vesion mean five outter can be 6mm
TUBE FITTING ,TWO FERRULE COMPRESSION FITTING - A-LOK® SERIES
YEP...10 thou is 254 microns...
that is the size of each of the tiny holes in the tube..
A flow rate will let you calculate how many holes you need for a particular application,or more precisely, what MAXIMUM amount each tube can pass..
it's the size of the holes I've been experimenting with..
Max got flashback with 12 thou multihole but no flashback with 12 thou single hole..more work to be done..also, like he pointed out, tubes may behave different to discs...don't know yet..Cheers...Paul.
The Above Picture show tube in the ferrule
we know believe this is fibre optic multi bore tubing
Can you buy it now ?
We are working hard on it we expect to post in stages ,
Will be in bigger rolls of tube only as new production
We will post price shortly.
We expect testing and support.
We will trail various fittings at same time in 2 mm and 4 mm
Stage 2 can buy any length and fitting will be off shelf easy!!
Price indication working on the various material type advise soon
in the mean time please share our pages every where partiality to lpg and hot rodder website groups clubs
"AN" Thread Sizes (Army/Navy Threads)
Commonly used on Nitrous Oxide systems. The sizing chart and numbering system was developed during World War II where the armed forces used Nitrous Oxide systems to boost the power output of aircraft engines.
AN sizes, originally developed for use by the U.S. Armed forces ("A" for army and "N" for navy), describe the outside diameter (O.D.) of tubing in 1/16-inch increments. For example, an AN 2 fitting will fit a tube with an O.D. of 2/16", or 1/8", while an AN 8 fitting will fit a tube with an O.D. of 8/16", or 1/2". Because the actual thickness of tube walls can vary from brand to brand, the inside diameter of a tube is not used as a reference. You will also find the dash (-) symbol or the word "dash" itself used in conjunction with AN sizes. A "dash six" fitting translates to AN-6.
Each AN fitting has an established thread sizing. The following chart shows the relationship between AN size, tube O.D., and SAE thread size:
"NPT" Thread Sizes (National Pipe Taper)
NPT sizes are the most commonly used fitting sizes for general plumbing, piping, and tubing use; not quite as popular as AN for automotive use, but still very common.
While AN fittings depend on the outside diameter of a tube for sizing, NPT fittings depend on the interior diameter (I.D.) of the fitting itself.
The following chart shows the each size's thread-per-inch count, the I.D. of the fitting, and the AN fitting size with the closest-matching I.D.(inside dimension).
AN Fitting and Hose Sizes
The Reasons Behind the Numbers
Ordering AN plumbing fittings can be confusing because the nomenclature does not directly translate into a thread size. Fortunately, each AN size will always correlate with one specific fitting size. There are no exceptions, so there is no guesswork. Measure the thread OD and pitch, and you know the fitting size.
The idea behind AN hoses and AN fittings was to provide a flexible alternative to rigid tubing in plumbing systems on aircraft and military vehicles. Sizes for rigid tubes were already standardized, with sizes called out by tubing OD (3/16", 1/2", etc). AN hose sizes were designed to match the ID sizes of these rigid tubes. Can you see the confusion starting? Tubing is known by OD, but AN hoses are sized according to the tubing ID -- not the hose OD or even the hose ID.
AN hose sizes are based on the nominal OD of the tubing with a matching ID. It sounds convoluted, but it really is a simple idea that achieves a logical goal. If hoses were called out using the hose OD (following the same system used for tubing), the ID of a 3/8" hose would be much smaller than the ID of a 3/8" tube. On top of that, different hose types have different wall thicknesses. That system would make it impossible to predict the hose size required for any application.
The AN numbers refer to the tubing OD in sixteenths of an inch. For example, 8AN hose has the same ID as a 1/2" nominal tube (8/16 = 1/2). 3AN hose has the same ID as a 3/16" tube. This means that 6AN hose will not introduce any appreciable flow restriction in a fuel system designed around 3/8" OD rigid tubing.
Note that this does not match AN Bolt Nomenclature. AN bolt sizes translate directly to bolt OD in sixteenths of an inch. To help differentiate between the two systems, convention has put the "AN" before the bolt size but after the plumbing size (e.g., AN4 bolts / 6AN hose).
The Bad News
When racers adopted AN plumbing, it soon became apparent that engineers in different industries did not work together much. Automotive designers had their own standards and accepted sizes, and some of those were not found in aircraft systems. One glaring mismatch is the popularity of 5/16" (8mm) fuel hose on automobiles. While a specification exists for 5AN hose and fittings, it is exceedingly rare in the aircraft industry. Even manufacturers specializing in AN-style fittings strictly for motorsports tend to skip over the 5AN size for the most part.
The Good News
As mentioned earlier, you can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).
Male Thread Size AN Size* Equivalent Tube Size (Nominal OD) Hose ID **Male fitting ID
3/8-24 3AN 3/16" 0.13" ** 0.12"
7/16-20 4AN 1/4" 0.22" 0.17"
9/16-18 6AN 3/8" 0.34" 0.30"
3/4-16 8AN 1/2" 0.44" 0.39"
7/8-14 10AN 5/8" 0.56" 0.48"
1 1/16-12 12AN 3/4" 0.69" 0.61"
1 5/16-12 16AN 1" 0.88" 0.84"
* Note that these are the same as SAE O-Ring Port sizes, but O-Ring Port size numbers are normally called out as dash numbers (-4, -6, etc).
** Conventional rubber-lined stainless braided hose, except 3AN which is PTFE-lined.
Tip: If you don't have a proper measuring tool handy, open-end wrenches make great "go-no go" gauges in a pinch! If a 7/16" wrench slips over the threads but a 3/8" wrench doesn't, you have a 4AN fitting.

Another name for "multi-bore" is "multi-lumen"
according to Zeus Inc.
"The numerous lumens, or 'passages' that can be designed into Zeus Multi-Lumen tubing, allow design engineers to push the creative envelope and expand the capabilities of their products."
.015-.025" holes with a 3/8" line??? of 3/8" OD...
These guys (http://precisionextrusion.com/infocontact.html) have a sample request form. I've no idea if they'll even do what we want. Worth a shot even if it is a small length of tubing. What I've uncovered is that... nearly all "multi-lumen" tubing is a custom order.
What if they're willing to make a few feet of your custom order? would you still be able to test it's viability? (I.E. can you use a small portion to test it as a "flashback arrestor")
Some other links to try.
