Grease Fitting Question Help!!!!

Hello all,

I am trying to find out if Grease Fitting # AC286-1 was superseded by MS part # MS15006-1. Also any information on what the abbreviation AC stands for in the part # would be great.

Thank you
Patrick

The dimensions of the two are the same, both having the 1/8 P.T.F. Thread.

http://www.ecasinc.com/pdf/ECAS_Catalog_Final.pdf Page 151 has the fitting with the dimensions.

Hello Patrick

I know I have MS15001-1 and MS15002-1 Lube fittings in stock, when I go back to the office tomorrow morning I will look up the Spec's and find out what the "AC" prefix stands for. MS refers to Military Standards, perhaps the AC is Aerospace Certified???

Here is what the AC and MS represent.
AC (Air Corps)
MS (Military Standard)
The MS part spec may contain information on what it replaces, get a copy and check.

I checked yesterday, but my odlest MS specs only go back to 1951 and it does not show what it supersedes.

I would think a grease (zerk) fitting is just that. As long as the size, material and thread type (striaght, taper or pipe) are the same then you should be able to use what ever is similar.

I think you are missing an intervening number. From what I know AC stood for Air Corps and noted only Army Air Corps specified parts. At some point either just before or during WW2 the Army and Navy got together long enough to come out with joint specifications for most aviation hardware. This was the AN series which stood for Army-Navy (and later for Air Force-Navy) or as my old instructor used to say Army-NAVY! One of my manuals shows the AN286 style of grease fittings. So I would think AC 286 was superseded by AN 286 and then probably by the MS1500 style.

AN = Air Force-Navy Aeronautical
AND = Air Force-Navy Aeronautical Design
MS = Military Standards

I did find a reference that said the "AN286 Inactive For Design -- Use MS15006"

A couple pages from a WWII Little Black Book which shows some background on how the AN series got started. The cover was gone when I received this but I believe it was published around 43/44.

Searching the Internet with the part number AN286 gets better results than AC286.

Here is a current supplier site that may help in the future:

The supplier provides part pictures in pdf with some part history:

All the best.
