stop leakage from a Co2 cartridge that has been pierced? I'm trying an experiment to see if it in fact works, I put plumbers tape on the cartridge in my Gamo P25, its been 2 weeks but I'm going to wait much longer to see if I get the same number of shots as if it were a fresh Co2. I think I'll give it a couple months to see how it does.
 
I had to read this two times to figure out. Your testing to see if you can keep a disposable co2 fully charged in an air gun without losing charge by sealing it with Teflon tape. Pierced but sealed.

I'll check back later

Exactly. I'm leaving it for another 2 weeks as is, then I'll see how many shots I get from it.
 
Using Teflon to help seal your co cart to the vlv assembly would be a temporary repair at best.
You need a new main seal on the vlv assembly unit. (might not sell the seal separate, just a new vlv assembly)

That being said, yes it does work, for how long not sure.

Watch the whole thing or start @ 2:40.

My pistol is pretty much new, the seal is fine.
 
If your Gamo doesn't hold air, and placing plumbers tape (what ever that is) on the end of the co2 cartridge before piercing it - makes it hold air, I would suggest that seal is faulty.

Actually, the gun is new, the seal is good. The purpose of this is to see if putting plumbers tape (Teflon tape) on the cartridge to see if the gun can hold the Co2 for a long period of time. I brought the gun down and was going to see what the shot count will be this weekend, it is normally around 30 shots due to it being a blowback pistol. So, I guess I'll find out.
 
It's been quite a few years since I completed my B.C. gas qualification but there is a trick question that is in the groups of questions directly related to this. I can't remember all four of the possible answers but only the correct one matters.
Q. What is the purpose of Teflon based thread applicants?
correct A. It is not a sealant. It is a thread lubricant.
Remember, Teflon is slippery. I have seen numerous times Teflon tape has been the cause of leaks and a ridiculous amount of times that alcohol based Teflon pipe joint compound has dried out and caused leaks years later. It simply allows the threads to engage smoothly so the sealing surfaces can engage fully without friction and heat distortion of surfaces. Cheers

Interesting.
 
I've seen a putty that is used with other gas plumbing that might work.
I don't know if it was a lead putty or what it is but it comes from the the plumbing/heating supply store.
When i bought my camper there was a container of it in the propane tank hold and it was used on all the fittings to prevent any kind of gas leak. The container .... and the camper are long gone or i'd go check
anyone know what I am talking about?

Why would you think plumbers tape will make any difference if the seal is good?
If the seal is good there is a possibility plumbers tape could cause a leakage.
 
Yet strangely it's also known as Thread Seal Tape.
Not by the product manufacture.
Teflon tape. Or Pipe joint compound with Teflon, will never have reference from manufacture as to be a thread sealant.
As a side note I should suggest googling Dupont, Teflon, to clarify it's purpose.
Physically if you prevent two surfaces from sticking to each other, they cannot form a seal. Sorry if it sounds simple. The physics come down to the tolerances of the mating surfaces and the pressures they are at in relation to each other, compared to the forces that are applied to them.
Teflon only allows you to engage the mating surfaces more efficiently. It cannot in it's own nature form a seal. As per the actual design manufacture.
I'm just pointing out the wives tale being perpetuated by someone on you tube, or the misinformation on some uninformed installation instructions from China.
But each to his own...
I will continue to work in my certified profession fixing these silly mistakes. Taking peoples money to fix leaks on compression fittings that have been fouled with Teflon tape in a sealing system designed not to have it.
Cheers

Ok sorry about the bold type Not sure how to change it. Anyway heres from wiki as they explain it better than I can even though I am a plumber I’m not gonna type that much! There are other colours as well for different applications and psi and are rated for different things like petroleum products for example. Yes it seals and yes it lubes and as for the “putty” while there is plumbers putty it is not used on threaded pipe that would be the “compound “ mentioned or as we call it “dope” and that as well comes in different types for different applications, some having lead and others not (for potable water application)

Be careful using too much tape as you can split the female joint, 3-4 wraps should do (in our application)

I don’t know how effective it will be in your situation and I didn’t watch the video but I just couldn’t watch this thread anymore without saying anything. I kept getting drawn to it because of the title lol

Just trying to clarify the “plumbers tape part” not trying to derail your thread or be a know it all.

Hope it works for you and here’s what I googled for ya…

Thread seal tape​

Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene(PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. Thread seal tape lubricates, allowing for a deeper seating of the threads, and it helps prevent the threads from seizing when being unscrewed.[1] The tape also works as a deformable filler and thread lubricant, helping to seal the joint without hardening or making it more difficult to tighten,[2] and instead making it easier to tighten.[1] It also protects the threads of both pieces from direct contact with each other and physical wear and helps seal and prevent leaks from the connection.
Thread seal tape is wrapped around the threads, lubricating the connection and allowing the two pieces to be screwed deeper together.
Typically the tape is wrapped in the same direction the male threads go for tightening and is commonly used commercially in applications including pressurized water systems, central heating systems, and air compression equipment.
Types
  • White: used on NPT threads up to 3⁄8 inch.
  • Yellow: used on NPT threads 1⁄2 inch to 2 inch, often labeled "gas tape"
  • Pink: used on NPT threads 1⁄2 inch to 2 inch, safe for potable water.
  • Green: oil-free PTFE used on oxygen lines and some specific medical gasses.

Dupont is the registered manufacture not WIKI. Wiki leaks LoL

Sorry I stand corrected.
There are others who refer to Teflon tape as a lubricant as well as aiding in forming a seal of the threads. Though the "threads" are not the sealing joint. Because Wiki says so..if read carefully.
Dupont, the patent owners, does not proclaim it is a sealant.
Lock Tight compounds are one of the forms that produce true thread sealants that contain Teflon. They are rated for strength of bond depending on thread type, tolerance, ductile strength and pressure levels. The key sealant in the bonding agent is cyanoacrylate. The Teflon is added as a release agent so the joint can be serviced. Again the function of the Teflon is to make things slip, not seal.
Is anyone aware that the addition of chrome to brass fittings isn't for looks? The chrome has a more lubricative quality than unfinished brass. Again adding to the ability of the actual "connection" surfaces to properly compress against each other, metal on metal or plastic on plastic.
When dealing with low pressure connections its no big deal. Do you ever hear of anyone installing Teflon tape on brake line connections? Instant lawsuit.
But lets make this really simple. Does the product manufacture say you can use it to form a seal on a "pressure joint" that the OP refers to? It does not. Though somebody on Utoobe who is completely unqualified does.
