High Pressure Grease

High pressure grease like those developed for early stainless steel guns for anti-galling such as RIG+. What's available today ? [ EP Grease ]

That would be EP grease.

Not needed for a gun.

I use synthetic as I got a combo order of that and oil.

Marketed specifically for guns.

There is not standard for gun grease. It can be anything someone puts in a tube or small tub including bacon grease. Guaranteed its repackaged grease from something.

Equipment greases do have standards. If you want an EP grease, then get something like Chevron, forget which type but your local petroleum company will have it, maybe local auto store.

I have gone through my own journey of understanding on gun grease. When I started out, I bought a tube of tetra grease with Teflon for guns. It worked fine for years.

Then I found, by accident, that the moly grease I used for auto repair actually worked better. I gave away the half tube of tetra grease to a friend, who was starting out as well.

Some years later I needed special grease for repairing some food processing appliance. I bought a tube of superlube synthetic grease. It worked as well as the moly , if not better. It is my first choice; it is clear, non-toxic and has very wide temperature range.

There are actually many choices without the "gun" label. They may work even better and are, almost for sure, cheaper.

Yep, as noted, oils and greases for machinery have specs. Very high quality control maintained (by the OEM like Chevron as well as the specialty guys you find in your local Bearing Store.)

Even some regional grease suppliers are iffy. One sold us grease for one use, they moved to use it everyone and when I tracked it down found it was not synthetic like the sale people claimed (and charged for)

Synthetic gun grease is going to be decent and likely re-packged from a good supplier, but costs a fair amount.

Nothing in a gun sees the type of action a gear does. Lugs simply have a single impulse, they are not bathed in grease and it just wipes off. In a bearing its replaced but in a gun it just squirts off to one side.

Open chain drives (Motorcycle) forget it. O ring chains helped a lot but.....

You can't keep a bicycle chain worth a hoot past 1000 miles. O ring types don't even help there (triple the cost and you may double the life, hmmm)

I am happy with the red Mobil1 synthetic grease, sold in the tubs. One tub will last you a lifetime.

If you have something like Browning O/U the forces on the hinge pin are high and there are also wiping action forces so an EP grade is suitable ! A small amount on the hinge pin and a standard grease for other parts. . A common example of wiping forces are found on automobile hypoid gears ! !

Won't hurt but not needed.
