What size grease gun?
I want to buy a grease gun to grease the nipples of my trailer. Had the trailer 20 years and never done it but as I have fitted "new" tyres and had some parts of the chassis replaced due to rust, caused I think by driving water spray I think greasing is well over due.
What do I measure on the nipple to work out what size grease gun? Although quite likely the nipples are imperial, an 8mm socket fits well. A Google search and I think 55nm is about right for the wheel nuts which are about a 10mm thread macafee2 |

A quick Google search indicates that there's a 'standard' size for grease nipples, which almost any gun you buy will fit. I think it's very unlikely that the trailer has a size different from standard. Any Halfords type grease gun will be OK.

I can't say i've ever seen different size grease nipples at least on automotive applications.

I went to look at a grease gun yesterday and came away unsure. Looking at Hilkas web site it says it will only fit 14mm nipples, which leads me to think there are a number of sizes of grease nipples.
14mm is quite some size for a grease nipple when it comes to automotive use and the explanation on the web site is unclear on what part of the grease nipple is used to measure 14mm. macafee2 |

Because the head of the grease nipple and the head of the grease gun are semi-circular the two will be self centring.
As long as the grease gun is in a straight line with the grease nipple the pressure between them will stop any grease leakage and the gun will do the job.------------- |

I have 2 boxes of grease nipples in my garage, left over from my trucking business. The guns were all the same size (1/8") apart from the Tecalemit slide on ones. The screw in thread sizes (where the nipple screws into the part to be greased) do vary though.
