Reusable epoxy applicator syringes that can be loaded with epoxy mixture or other adhesives for injecting into tight spots. The smaller syringe from West System has a slight curve in the tip to improve application. The larger 60cc syringe has a straight tip and delivers more material with greater pressure.

What is the diameter of the WSY 807 syringe?
The WSY-807 is 5/8" diameter.

Can the 60cc syringe handle epoxy thickened with collodial (not sure on spelling) material to a consistency roughly that of pancake batter?
yes, I think it can. have not used it that way, but think it sgould work. good luck.
sure. you have to decide where to cut the tip to make the opening big enough to pass the contents but small enough to fit into the hole you want to put the syringe in.for pancake batter it wont need to be that big.
Is it possible to fill the syringe by inserting the syringe tip into caulking (which I intend to use it for) and drawing the caulk into the syringe? I can't insert the caulk from a caulking gun directly into the syringe because I plan to pre mix the caulk with a fine stainless steel powder prior to drawing to give it weight.
Thanks much for the info.
Thanks for the information. I'll give it a try.
I have never had any luck drawing thickened epoxies up through to spout of the syringe. Just too thick. Get some artist pallet knives (around 2.75) and trowel it in from the other end. Patience is good here.
Not sure what "caulking" material you plan on using, but epoxy thickened with wood flour, cab-o-sil, West system 404 high density filler, or West System 410 Micro-light filler can be drawn up through the tip if it is thickened to the consistency of mustard. If it is thickened to mayonnaise or peanunt butter thickness then you can removed the plunger and use a mixing stick to press it in from the top. Assuming your "caulk" is the consistency of silicon or latex caulk, then you will need to fill the syringe from the top, insert the plunger and dispense.
Gerald B responded: The viscosity of the caulk will probably be too great to pull through the nozzle of the syringe. I would suggest pulling the plunger out of the syringe and filling from the end. The use of fine SS powder with the caulk may breakup the caulk polymer; with heat from sunlight, this could be a early problem. Fillers for plastic compounds must be low in metals to avoid grazing (from polymer breakdown). I think I remember epoxy is not so prone to this issue. If you want weight why not add barium sulfate (barite); its a weighting agent and probably would be light gray in color, and low cost. Go to a well drilling supplier for a bag, paint filler grades are whiter.
Thanks for the feedback!
That may be difficult because the opening at the end of the syringe is small. Two solutions, take a drill and widen the opening or remove the plunger and put the premixed caulk in from the back. It is a trial and error procedure depending on the consistency of the caulk.
Thanks kindly for the suggestion!
What is the outside diameter of the tip of the larger 60cc syringe? In other words, how small of a hole can I fit the tip into?
The outside diameter of the tip is .259 inches, thanks.
I need to force caulk into a tight spot. The caulk is Dow Corning 795. Is this syringe the right tool?
If the caulk is soft enough, it will probably flow pretty well. What you may also try is just using clear tubing and force it on the tip of the caulk tube and then bend the tube to where you have to put the caulk. You may also put a piece of duct tape on the connection from the tubing to the tip of the caulk tube. Good luck.
I have not used the ones I bought.
Well Donald, get to it.
Thank you John
what do you do with the epoxy?
Squirt it in hard to reach places. Force it into no longer needed drill holes.
You must squirt into a puddle or pot in order to mix it well before spreading on your work with a stick or something. I like to read the directions for best practices. Does this answer the question?
Mix the epoxy in a pail according to directions and pour small quantities into syringe. Reuse syringe as long as epoxy has not begun to set up. Keep enough spare syringes on hand to do the entire job. They are inexpensive.We use syringes for Wood Epoxy Repair (Google: "wood epoxy repair" to learn about techniques and applications) mostly for rotted or decayed wood that still retains enough of its original material and form that it can absorb the epoxy. Drill a series of 1/4" diameter holes and inject the expoxy into them. Depending on the amount of decay, the spacing of the holes will vary. But you will get the feel of how well the epoxiy is working to consolidate the decayed wood. It is a very effective technique. (Also quite messy as the epoxy drips everywhere!)
Will purchase again
Used to encapsulate electronic circuit boards
works great for injecting epoxy into small cracks
Great handy measuring tool
This is a super handy disposable tool. Great for measuring out resin or even transfering or extracting small amounts of fluid.
Cape Cod, MA
It works well for filling small holes and it doesn't stick to the adhesive.
Used for repairing all types of fiberglass boards.
I use these to measure small batches of epoxy. One for resin and another for hardener. Gives very accurate measure and can be reused several times. Provided of course you keep 'em separate. One for epoxy, one for resin

They really work and save time
Slowly does it

Perfect for resin injection
Great for injecting resin into due lamenting fiberglass
Does the job
Works great for injecting CPES into small holes
Syringes useful for precise application
Syringes are hard enough to use that you won't want to use them if you don't have to, but they are the best way I know to apply small amounts of epoxy with precision. Done carefully, you can avoid getting glue where you don't want it- you can even drill a hole and force glue into an existing joint.Incidentally, if you clean out the syringe real well right away, using either vinegar or alcohol, the syringes can be used repeatedly.
