grease gun nipples

[cruzin]

Hello.
I had a nice little grease gun that took the 5-6 inch cartridges. The drawback was I had to buy three different kinds of grease in the pack. So I bought a performance tool grease gun with the 14" cartridge. I use it for the fittings on the wheels which I never had a problem with my other trailers using the old gun. The problem I have is the nipple on the new grease gun does not fit on the zerk fitting. So...Does anyone know the size nipple I should get? I have an imagine 2020 rb2600 with the E rated tires. Thank you

All grease guns should fit all of the grease zerk fittings , standard or metric included. I have not had to change the end on a grease gun because it would not fit a grease fitting. I have had to change an end because it was wore out and would not hold on to the fitting. If the grease fitting is not accepting grease it may be dried up inside or in case of the hanger bolts the cross hole may not be oriented in the 3 or 9 o-clock position.

Maybe just replace the coupler on the grease gun. It may not be working properly.

Thanks for the replies. I'll go buy another nipple. I pushed as hard as I could and it just wouldn't go on the fitting.

Grease gun 101 here. Most not all grease end fittings are adjustable. Most of them come in completely tight. It may take a pair of pliers to unscrew the working end of the fitting to loosen up the jaws.

I have seen them so cranked down, that if you do get it to clamp, you will never get it off.

Note that he is spinning the non hose end to change the clamping force on the zerk.

The only other issue I have had is the fitting not physically fitting into the opening the zerk was buried in. That's where this little friend of mine comes in https://www.amazon.com/LockNLube-Nar...xpY2s9dHJ1ZQ== just put the little end against the ball on the zerk and pump away.

Good grief! I'm 62 years old and just learned this??? THANK YOU for sharing this information!

Me too! I guess old dogs can learn. Maybe now I can adjust the coupler and not use a prybar to get the coupler off the zerk on my jet pump.

Well Guys back somewhere close to 40 years ago when I did not have enough body or hand strength to force couplers on and off of zerk fittings when helping dad, he taught me that trick (There are countless others as well).

One would think that Zerk fitting shape would be pretty much a standard by that day in age. Well I can tell you they were not. I could get the nipple on some fittings but not others and dad was too busy working on other things, so he showed me how to adjust the head to get the nipple on and off.

Be advised that if you get the nipple too loose, it will leak. I have had some stubborn Zerks require that I crank down the nipple after it slips on to stop the leaking. With my needle, I crank it down also (now I have a lock-n-lube end on the primary gun) then just use the fine tip to get grease in the fittings.

I originally bought the needle for greasing https://www.amazon.com/Moog-620-Flus.../dp/B0093XUVW2 on my driveline U-joints. But since have found multiple uses for it.

To the OP these are a bit pricey (avoid the knock off it breaks before you install it) https://www.amazon.com/LockNLube-fit.../dp/B00H7LPKKU but well worth the money for ease of use.

There are some great tips in this thread. cruzin - Just to let you know, most of us do not lubricate the hub fittings on our RVs. We've had conversations with Lippert and Dexter technicians and they told us those fittings are primarily used when the axle is installed on boats. The same type of axles and hubs can be installed in both RV and boat trailer applications. After submersion in water, a shot of grease in the hubs will displace water on a boat trailer axle. They have told us that on an RV, the only greasing that is needed is during the annual bearing repack and inspection. Their primary concern was that sometimes using a grease gun on the hubs will allow grease to get past the seal and into the brake chamber.

Ge this and never look back. You can find them at your hardware store or online. Mine came in a 2 pack (short and long) with extra parts.

Sorry I forgot to post back. I called performance tool and they said the coupler was adjustable. (before I read the other replies saying the were adjustable. Anyway, no matter what I did adjusting in or out, It still wouldn't fit so i took the one off the old gun and works fine now. Thanks for the replies and sorry for the late post.
