MHC_TXHinge Pin Grease
Hinge Pin Grease - what do you use or recommend for lubricating the hinge pin on your double rifle or shotgun? Does it matter? If so, what do you use and where do you get it?
Thanks!

pagosawingnutI use MilComm TW25B. Best gun grease I've ever found. I think Butch Searcy was sending a tube of it out with his doubles after he tried it.

cal pappasVaseline is the approximate some consistency as many specialty "hinge pin greases". Bearing grease is fine, too.

shootawayToo much grease can cause wear,IMO.The thinnest film possible-especially in tight tolerance applications.

Greasing a hinge pin excessively would not cause wear. Any amount you put will be swept aside once parts are assembled, and grease will remain in the form of a thin film embedded in the surface pores of the metal. The excess grease would catch solid particles and cause gumming though.

MartyTetra gun grease. It's a lot less messy than stuff with graphite and moly.

Grease is like a liquid.It does not compress and if you put to much it will put pressure on all metal parts including the hing pin.

Milo ShanghaiFor the last few years I have used Clenzoil hinge pin jelly and it seems to work well.
I use automotive synthetic grease...

It will get wiped away as the hinge is worked. There is no place that is going to hold grease to the pressures that would cause damage to the arm.
If ignorance is bliss; there are some blissful sonofaguns around here. We know who you are, so no reason to point yourselves out.
The greases are normally the EP grades like those used for lubing the Hypoid gears on a rear wheel drive car .Those greases are made for high pressure and a wiping action . These are similar to the lubes sold for the early stainless steel guns before they figured out what stainless grades to use .I still have some RIG + P which is made for this.Other similar greases work well too.Put some on the locking wedges too.

sambarman338Where does white lithium fit into these recommendations? There used to be an English gun maker on one of these forums who said that was best and that he'd never needed to rejoint a gun or rifle that had been lubricated with it, IIRC.
I'm not sure I've even seen the stuff he meant or how he could pin it down as so good.

Lithium is contained in most EP (extreme pressure ) greases. I use a lithium EP grease from Lubrication Engineers Inc. Was rather expensive at about $30 a tube 25 years ago but have been fastidious in applying a small squirt from a syringe on the hinge pin of my Miroku O/U shotgun over all those years and it is still as tight as the day it was new despite 1000s of rounds of use in clay target competition and hunting.

MacD37I use MILITEC-1 grease on the hinge pin!
- Stays in place and lubricates in severe conditions.
- Excellent water wash out resistance.
- Superior shock-load protection
- reduces corrosion wear and galling
