User questions & answers

Question:	Is this fuel resistance
Answer:	Yes it is, and oil resistant as well. Great sealant, which I used on my experimental aircraft engine fittings.
Question:	I was told i could use this on an oil pressure sending unit and seen on websites it could be used. so someone just told me I shouldn't. So can i
Answer:	Depends on whether its oil resistant or not! Haven't used it for anything like that!
Question:	Does this product solidify after 72 hrs as cited in the tds? after being applied for 52 hrs it remains a soft tacky paste
Answer:	Hello. I use this product quite often. It holds very well, seals very well. I just put some on my differential fill plug and seals it great. To answer your question, this product, when first put on threaded hardware will be wet and soft and be able to seal low pressure and intermediate pressure. Parts can be readjusted, torqued, etcetera with in 24 hours of application. 72 hours just means it is fully cured and can withstand higher pressures. But, once applied, it holds very well within hours. Definitely within 24 hours. It does not solidify, it stays wet and soft. It's good stuff. Hope this helped. BJ
Question:	How hard is to unscrew after this has been set for awhile
Answer:	Harder than unscrewing a light bulb, yet not as hard as unscrewing your gf after she tells you she’s pregnant.....

User questions & answers

Question:	What's the difference between this & Special Edition? I need 2 use it 2 seal inline fuel filter thread brass fitting 4 a motorcycle tank 2 carb
Answer:	To big, larger than regular spools, so it wobbles
Question:	What's the difference between this & Special Edition? I need 2 use it 2 seal inline fuel filter thread brass fitting 4 a motorcycle tank 2 carb
Answer:	Yes they are regular sized spools.
Question:	Can this be used on plastic pipe
Answer:	No it is more suited to sewing clothing.
Question:	Does this stuff seal pneumatic (800 psi) threads on an and npt fittings
Answer:	Probably not. It comes with X-Large bowls and a larger slip lead that would be too big for a small dog. I would order the small/medium in the backpack, it comes with 2 bags of food that would feed 2 small dogs under 20lbs for 72 hours and there would be enough water as well. You might want to add 1 extra bowl and an extra slip lead. Hope that helps. If you need any assistance check out our website at www.petevacpak.com for emergency preparedness tips. Team Pet Evac Pak

Answer:	I had to the tip of a sewing pin, running it up & down across the spool to find the RIGHT end. It is NOT the the string which is at the top of the spool. I will never buy this again. I finally had to throw 5 spools in the trash.

Product description

Threadlocker Blue 242 is designed to lock and seal threaded fasteners that require normal disassembly with standard hand tools. Its advanced formula cures when it's confined in the absence of air between close-fitting metal surfaces to prevent the loosening of metal fasteners caused by vibrations. Plus, it protects threads from rust and corrosion to keep them working properly for longer. Threadlocker Blue 242 is particularly suited for applications on less active substrates such as stainless steel and plated surfaces, where disassembly is required for servicing.

From the Manufacturer

Loctite Threadlocker Blue 242 locks threaded metal fasteners against loosening from machine vibration. It prevents leaks and rusting of metal threads for 1/4- to 3/4-Inch (6 mm to 20 mm) nuts and bolts. Metal parts can be removed with hand tools for easy disassembly if necessary. Sets in 20 minutes and cures in 24 hours. Especially useful for small motors, mowers and many types of power equipment.

• Advanced formula prevents loosening of metal fasteners caused by vibrations
• Protective design protects threads from rusting and corroding
• Medium-strength allows nuts and bolts to be removed with hand tools
• Locks and seals threaded fasteners that require disassembly

User questions & answers

Question:	I'm joinng 2 20' pieces of pipe togther for a weather station pole (outdoors, rain, heat). Which loctite is best
Answer:	Blue is for bigger gaps like pipe threads, its thicker. Red is super high strength. I would use regular pipe dope, paste. Case you ever take it apart. If it is never coming aoart, don't use anything it'll rust and be solid.
Question:	how do I open the sealed tube? do I just poke a hole at the top
Answer:	I think it's best to use a thumbtack, safety pin, etc. to poke a hole into the flat tip. This will give you "droplet-sized control" in application.
Question:	Do I apply this to my doorknob set screw before screwing it in or after? (ie, a drop on top
Answer:	I have only used it on the screws that hold the wood grips onto a hand gun. Those would always work their way out after just 50 rounds, but now I never have a problem. Plus since I didn't use a ton of the glue, I can always get the grips off again if I should want to swap them out. Other than that, I have never had much need for loctite. You'll find that a lot of shooters use this stuff on all sorts of shooting apparatus!
Question:	Is there a solvent or dremel attachement that will remove this stuff from bolt threads
Answer:	You don't need solvent or dremel. It will keep any screw or bolt from loosening, but you can get the bolt/screw out with a screwdriver and just brush off the Loctite. Very good stuff.

User questions & answers

Question:	Can you use this to seal the pipe fittings for a gas stove
Answer:	I apologise but I m not qualified to answer this. I've never used this on twist lock fuel fittings. I've only used this on fasteners. How about aluminum anti-sieze for fuel fasteners?
Question:	can this be used safely on leaking faucet in kitchen sink
Answer:	Brake line fittings don’t use thread sealant. Brake lines usually use a flared seal. If any sealant was to be used, I would use something like a anerobic sealant
Question:	I need to seal gas pipes of my fireplace burner which sits hot in the fireplace. Would this do the job
Answer:	The special edition is no doubt like many other products listed on Amazon a seller attempting to use the false label of a "special edition" to lure buyers to buy from them at a higher price, without prime shipping and more often than not slower shipping. I am willing to bet if you contact the maker of the product that they do not produce a "special edition".
Question:	How long does it take to set? Can it be put in use immediatley
Answer:	I tried a number of things to seal a brass tee into a motorcycle oil pressure outlet. Nothing worked 'til I tried this stuff. Be sure to clean the threads well beforehand. If the stuff is rated for fuel, I'm sure it'll work for your application. It's good stuff.

User questions & answers

Question:	Will this work for a pressure pot with a 40 to 45 PSI
Answer:	What is on your valves is exactly this Loctite product. Primary use is sealant in place "as supplied" from the manufacturer.
Question:	Can this be used for potable water tank spigots
Answer:	It probably will for a while , but it will leak again . If the fitting is loose you could try teflon tape or you could try to tap the hole out a little and try to turn the fitting one complete turn to get it to tighten up.
Question:	Can you use this and teflon tape? my taped plastic threads are leaking on my in-line water filter and i don't want to try more than one fix
Answer:	To my knowledge it will only work if you put it inside the threads - as you are assembling it. And it works pretty well doing that. Worked on a 3000+ psi hydraulic connection that was continually leaking.
Question:	Will this work on my cpvc to watwr supply line under my sink? Teflon tape didnt work. Small drip every minute
Answer:	Dries semi hard but hard enough that you can leave a fingernail imprint. it's not difficult to disassemble anything. I really like this stuff

User questions & answers

Question:	can this be used on lp (propane lines
Answer:	I don’t see why not.....I used it to seal pipe fittings on my gas furnace last year and I’m still alive and well.
Question:	Has anyone used this on fittings that are exposed to engine oil
Answer:	Yes, you can use this on a threaded connection on a kitchen faucet. However, it would be easier if you used teflon tape wound twice around the male connection threads. Gasoila is better when you have gas or oil connections (hence the name) where you couldn't use teflon because it would dissolve.
Question:	Will this work on gas tank drain plug that is leaking slightly
Answer:	This doesn't work over 600F.

Question:	Is this sealant approved for use with gasoline fitting applications
Answer:	Since it sets soft it is pretty much good to go immediately - the can does not list a minimum set time before use. I put it on a garden hose and used it right away with no problems.

Answer:	Hello, I don't know when the product I purchased was manufactured but I can tell you it seemed "fresh". Here is what I do to help it flow better: Fill a pan of water, put it on a Hot Plate and put the bottle of Gasoila in the water. As it heats up it thins out and is easier to apply. I hope this helps you out.

User questions & answers

Question:	How easy is it to break the seal when you want to remove a hose from a faucet
Answer:	Depends on why the plug is leaking. If the plug is threaded and the threads are damaged, probably not. If by "slightly" you mean weeping and if the threads are ok, then it may be sufficient. The reason that I used Gasoila E-seal was because of its resistance to degradation by Ethanol, especially in high percentage Ethanol/Gasoline blends. The product is a sealer, not a glue or filler.
Question:	is this 520 inches per roll
Answer:	It is specially designed for use in fittings handling gasoline and gasoline blends up to 85% ethanol. See technical specs here: https://www.fedprobrands.com/products/pipe-thread-sealants/gasoila-e-seal-thread-sealant.html
Question:	How easy is it to break the seal when you want to remove a hose from a faucet
