I have a regular grease gun fitting that is in a recessed locaton and I cannot get a grease gun on it. I looked for a small-head (small diameter) extension like they used to sell but no dice at NAPA. I did buy a small-head extension that you just press on the end of the fitting in a surface-to-surface way but grease goes everywhere.
I could also get by if I could find a regular -straight only---size small grease fitting that is longer than normal and then it would reach beyond the recessed hole it sits in. I didn't search yet in hopes someone here can offer the info. This not a foreign piece of junk but rather high quality American with this one particular oddity.

Does anyone know if a small-diamer lock-on grease gun extension is still available OR does anyone know if a longer than normal standard size SAE thread grease fitting is available?
Thanks in advance.

Have you tried a needle tip on your grease gun. You can poke the end of the needle into the center of the zerk and usually get it to take grease.

Bill, Great minds think alike ;)

Sixdogs, please don't double post. Check your post in Grease and Lubrication.

I routinely use pipes to extend fittings out for easy access. Vibration may be an issue though, or a rotation problem.

Would something like this work?

I have seen some grease guns with a coupler that is verry large and that might be your problem. Lincoln makes the smallest dia. coupler I have found .

BHD--thanks for the effort and I'm checking it out. I can access JD parts so I can look.
Bill--There is a difference between the largest diameter grease gun head and what is now called the standard head but there used to be a very small diameter slip-on adapter that fit, now tht I remember, between the yokes of a u-joint when tilted and hard to access. I am going to call Lincoln today.
Since you are a car guy, this is for a street rod I just finished and the front king pin grease fittings are recessed just a bit and difficult to access. I am first a tractor guy but here is the car photo...it came out better than I expected. A small head adapter would have many tractor and equipment applications as well.
