Using WD40 on air rifles.

[rabbitwrecker]

Myself i always give a squirt down the port hole of my 177 77k , just a little then decocked the gun and half pulled on the under lever a couple times and then left over night if I went shooting the morning after

I take it you'd get a few supersonic shots from that little routine....

The main thing to watch for is seals. If you leave it on them it can cause them to fail.

Yeah dead right.
I've been an engineering manager for over 30 yrs and while WD40 has it's uses on externals never allow it to penertrate the internals. Complex pneumatic valves in high speed production machinery was very often ruined when WD40 was used as an easy fix for sticking valves. It destroys air seals very quickly.

no small wonder really ....it has cutting agents in it for the purpose of degreasing.

Personally.... I just love the smell of it. I had an aunt who used to spray her arthritic hip evey day with it convinced that it was doing her good. She was (of course) barking mad.

Lmao...there may well be a nugget of truth in that,wd40 was iirc made from fish oil many many moons ago,a sort of 'cod liver oil' in an aerosol

fish oil ? nope

What a Fish story!
Myth: WD-40® contains fish oil.

Fact: Consumers have told us over the years that they have caught some of the biggest fish ever after protecting their fish hooks and lures with WD-40®. We believe this legend came from folks assuming that the product must contain fish oil since it appears to attract fish. Sorry Charlie®, it just ain’t so.
WD-40 Company has taken steps to respect and conserve the environment, and encourages its users to do the same. While WD-40® can be used to help protect fishing equipment from rust and corrosion, WD-40 Company does not recommend using WD-40® to attract fish.

“WD-40® Cures Arthritis!” No Way.
Myth: WD-40® cures arthritis.

Fact: This popular headline, appearing at least once a year in the tabloids, is completely FALSE. WD-40 Company does not recommend the use of WD-40® for medical purposes, and knows no reason why WD-40® would be effective for arthritis pain relief. WD-40® contains petroleum distillates and should be handled with the same precautions for any product containing this type of material

Actually had a doctor tell us that it works for joint pains. It has a chemical that allows it to penetrate the skin. Has a long name, but it well know by it's anagram. I just can't remember the 4 letters.

[dayglowfroggy]

There are better penetrating sprays out there but they are not as easy to get hold of.
I used to use them to free testing ports on power station stacks, very rusty and had been very hot.
But I have been using dw40 to clean inside the barrels recently seems good.

For all that matters the main ingredient in WD 40 is apparently Fish Oil. Make of it what you may.

For what it's worth I once experimented by leaving an O-ring soaking in WD40 for a month.
It had no discernible effect, and the o-ring sealed fine afterwards

WD40,Water displacement for fourty days and fourty nights?.

I prefer three in one.

[bighit]

fourty?

What does WD-40® stand for?
WD-40® literally stands for Water Displacement, 40th formula. That's the name straight out of the lab book used by the chemist who developed the product back in 1953. The chemist, Norm Larsen, was attempting to concoct a formula to prevent corrosion—a task which is done by displacing water. Norm's persistence paid off when he perfected the formula on his 40th try.

I have used wd40 on shuttle valves in offshore compressors to free off the shuttle valves .never had it wreck the seals .it just got blown out by the air. silicone grease or red rubber grease ( bit too thick) was used when rebuilding them. out on the job and no time to strip and clean it was wd40 or airtool oil that was used to free it off.
