In my many years (23) as a military aircraft mechanic, our Technical Orders had us use petrolatum jelly to lubricate our o-rings during reassembly. On our $285,000,000.00 aircraft. So...
I worked in a textile plant and helped two older gentleman who were much more experienced than I replace O-rings in air jet nozzles. They always had me lubricate the O-rings up in petroleum jelly. Another technician who was known to not be so smart told us that it would break the O-rings down. One of the older gentlemen I was working with said that they both had petroleum in them, so why would they destroy them? It made sense to me at the time, but then I read something online that talked about "like dissolves like". I read about this a little bit but still didn't completely comprehend it. Recently, I was told that you just can't use petroleum jelly on natural rubber O-rings, but you can on synthetic.

The problem is that "synthetic o-ring" can vary a lot in terms of raw materials. This means it is unlikely to have undergone comprehensive testing with petroleum jelly. For example, the uncommon latex o-ring is extremely sensitive to vaseline contact, just like natural rubber.
Our standard response, along with the seal manufacturers, is that natural rubber does not fair well against oil resistance and neither does EPDM (ethylene propylene) or Buna (commonly in pump seals). For the simple reason of acting on the side of caution, we always suggest a teflon or silicone based lubricant. You still risk an EPDM o-ring swelling or a Buna seal breaking down when vaseline is applied.
Go ahead and use Vaseline - you will learn the hard way. Smarter to follow the manufacturer’s research and recommendations which are silicone based lubricants
@@drdrew3I thought I could add my bit😊: For automotive rubber orings, there is a special "rubber grease" as well. It is red and very messy so probably not a good idea around pools. If I understand, they are made with castor oil and clay (among other things). I am in Australia where silicone grease is very hard to find.
latex is a polymer emulsion in water. companies make o-rings out of latex. latex is damaged by petroleum jelly. your comment is not about pool seals neither is mine, but your generalization is not at all correct.
I have never seen vaseline destroyed any rubber but if anyone is afraid of petroleum based lubricant u can use lanolin just like vaseline and it is sheep based.
no way, is vaseline bad for O-rings, Vaseline nice job and good for 100 years, also for your car door rubbers,heat up 50°C and spray with a large syringe and PVC hose / straw between your window and window rubber in the inner door of your car against rust on the underside of the car door. .
That's probably the most convincing argument so far. If, having read the entire internet, one determines that petroleum jelly is good enough for an o-ring, then that's good enough for me.

Vaseline doesn't seem to impact the neoprene or nitrile gaskets/o-rings.
Sorry, but Rob is just not someone I would ever trust, and and Matt seems an instigator. Can't say I would turn my back on either... Maybe it's the subject, but these are the guys that would get you into trouble in college...

Dang DAVE! 😆 Cheap fix not so cheap fix via the long run! So what to use then? Not military grade but more civilian?
That sounds like typical government based reasoning: use 5 cent lubricant on a $5,000 dollar part. I can’t even
Don't worry about the long term budget guys, there are a few million tax payers sharing the bill😂

off topic but i love the guys energy a real dynamic duo
Thank you! We appreciate the appreciation. 😁
Nothing is made of natural rubber though it's all synthetic
What about latex o-rings?
Can you guys help me I can’t get the band clap on my pool body filter container I’m struggling to get it on
Sure would be nice if you told us a product, pretty sure that’s why the guy was asking
We mention at the 1:18 mark that a silicone or teflon based lubricant should be used. If you need a brand recommendation, try Magic Lube.
Magic lube is the lube my compMy usez
Funniest lube vid so far 😂😂
the boyband references made y'all my new favorites! Thank you for the info
O-ringsare NOT rubber!! They are a POLYMER and vasaline IS safe to use on them!!

No. You’re wrong. Use silicone grease

Most orings in plumbing and automotive ARE rubber.
@@richardm.9821 again, not all polymers are the same. synthetic rubber can be made of many things
Bullshit ends at 1:09
bard ai just told me to vaseline the oring grooves

@@pocket83squared😂good point
It is just a way for Pinch a Penny to sell you 12 oz for $14.00. Buy a jar of Vaseline 16 oz for $5.99..
Are these guys a joke or what. Clearly have no idea on the compounds used to make o rings

But this is our day job. :(
