What is throat seal oil?4/25
We have 3 AAA spray pumps (all CA Technologies) and they need the small cup to remain filled with throat seal oil.
I understand the need for it, and it doesn't take much, but paying $17 for a pint of what appears to be just cheap mineral oil is rather ridiculous.
I've spoken to them before about it and they will neither confirm nor deny what it really is.
Anyone here just using regular old mineral oil?
It is not mineral oil, it is a resin called Dioctyl Phthalate, which means it compatible with a host of different coatings that may be pumped through a unit such as yours.
fwiw, i use mineral oil as it is an inert oil most will probably disagree but i have never had an issue using it for many years
I'm like Herb, I use mineral oil. I use pre-cats, post cats and 2k Polys. Never had an issue. $2/pint
How much of that oil do you guys go though ?I've had my Kremlin 9 years and I'm still working from the original bottle of oil that came with it .
I'm with tom, unless you're rebuilding your pumps multiple times a year and starting with fresh oil each time, how the heck are you running through it. On my second bottle in over 10 years.
I just reloaded my bottle for the third time. It's an 8 oz bottle.
I use my Kremlin out in the field on occasion and I empty the chamber when I do that and throw it away.
My pump hasn't been rebuilt and it's about 12 years old now. The seal leaks a small amount and when I use 2K the poly gets into the oil cup area and hardens. So I need to change the oil at that point. So in 12 years I've used 16 oz.
Leo rebuild that thing, I was just the same, waited till the thing finally "puked" which was when the springs internally finally got so worn out it wouldn't return at top or bottom of stroke. Its like $150ish to rebuild plus about half-1day to do it right. To be honest if you can bite the bullet i'd get a second pump because in the past 12 years the technology on the pump side has been upgraded a few times. You dont realize how shot ur pump is till u pull the trigger on a fresh one. Then just send ur old pump out to get rebuilt. Kinda more hassle than its worth doing urself.
Pump works good. Motor works good too. I can have it cycle thinner with zero pressure on the gauge.
And like everything I own, I'll burn it into the ground LOL.
You guys are correct that a bottle lasts a long time. With three pumps used nearly every day, our quart lasted about 3 years.
However, I have them clean out the cups more frequently than most.
It just bothers me to see something that costs $17/pint when it looks for all the world to be a $2 bottle of dollar store mineral oil.
Same thing with "butcher block oil". Most of them are just rebottled mineral oil. The fancy bottle cost more than the oil inside did.
