Grease gun for oil.

I bought one of these for oiling the nipples on my machines.

I can't get it to work! Can anyone confirm that they are suitable for use with oil rather than grease?!

Thanks.

No those are made to fit on this type of grease nipple

I suspect your machine has button oilers like these which are best filled using a decent oil can with a fine spout such as Reilang

Thanks for the reply.

It is this sort of nipple:

Welcome to the long running debate about oilers Chris. You have the Myford type of oil nipples and finding a suitable oiler that does not leak oil all over the place is not easy. The ones supplied by Myford when the company was still alive were prety poor and I suspect they were meant for grease.

It is possible to adapt a grease gun for use with oil (details on internet ) and I have been meaning to try this for ages, but might just give it a go now that you have indirectly reminded me.

Several of my machine tools have nipples identical to that shown by Chris, but are definitely intended for oil rather than grease.

However, the gun linked to in the original post says for grease, so no, it is not suitable for oil. Even the ones I have specifically designed for oil have a propensity to leak as much oil as gets into the slideways.

Hi

This one works with oil and fits Myford nipples the price is right as well, it was recomended to me by someone on this forum very pleased with it.

Hi Chris, Looking at the grease gun & your grease nipple, it should work with oil or grease. What is it doing/not doing? Does it work OK with grease? Some nipples have a flat top,as in Myford ML7. Regards, Bear..

I've never used one of these before.

I unscrew the cap at the end then pull out the rubber bung which is attached the the mechanism, then pour oil inside. The oil goes inbetween the outside casing and the internal cylinder.

Do I need to fill the cylinder where the piston is to prime it or something?

As it's a new gun, have you given it a good pumping to prime the inside cylinder. If it has a tight seal at the back end then it might be OK with oil, but be prepared for some leaks.

I have found that that type of grease nipple head on the gun will fit onto Myford domed nipples, but won't come off! You need to slacken its grip by unscrewing the head from the stem.

Chris, A little more information for you.Cromwell Tools are listing a Lumatic 31650 grease/oil gun, Part No CTL 5404526B, for £15.59 incl VAT.

Thanks for that.

PIT tried it again last night and got it working, I need to fill the inner cylinder as well.

It doesn't seem to be able to get oil though the nipple though. I put a nipple in a vice and used the grease gun but it didn't go through the nipple, I bought a new nipple to try today and still the oil doesn't get through to the inside of the nipple. Although when you remove the grease gun from the nipple there is pressure there.

Do I just need a more powerful oil gun?

Olly,

Thanks for that recommendation.

Please could you let me know what physical size this oil gun is and what oil capacity it is?

Do you have any leakage issues with it?

Many thanks,
Stephen S.

One thing I have found is that placing one thickness of clean cloth between the nipple and the oil gun stops the leakage at that point.

regards the cap leaking, try and get a leather washer that is a good fit in the cap. The nipple that will not let oil through is quite a common thing, the one on my tail stock is the same. I fitted a new one and now it is fine.

I tried it in a few nipples. The oil only comes out after you remove the pump from the nipple, it obviously won't go through the nipple ut there is a build up of pressure before the nipple.

I tried a grease gun I found on one last night and it was fine so I've ordered another grease gun of the same design.

Thanks.

Perhaps manufacturers of top quality modern nipples don't pay much attention to over strong springs. If only you knew a clever model engineer he might make you a special nozzle with pin to depress the ball seal (like on car air pumps) and an o-ring seal around the join.

I have had this issue. I have started to use elkalub grease and they have the nipples to. These are Germany and are really robust.

Mine is a Wanner 300-1. It works every time, but I bet it wasn't cheap

-£84.54 from here (no affiliation etc), indeed they are very good.

One thing about High Pressure grease guns is that they will blow oil seals if you are not careful.
