Technical Cover the zerke and protect the nuts

Pics of pieces you might find useful.
The machined and knurled aluminum caps fit onto zerke fittings and are secured with an internal O ring.
The molded plastic inserts fit into box wrenches and protect plated nuts and bolt heads.
Contact info is visible on the pictured package labels. All reasonable priced.

 

Those are nice and more user friendly.
I have these “dress up” caps but zerk has to be removed so I’ve never used them

 

TOTAL T buckets sold me some red ones that just snap on...

 

Mc Master Carr has them in blue

 

Great stuff @john worden...how long have those knurled covers been around? Thanks for sharing...

 

Would they also work on brake bleeders?

 

In an effort to not drift too far on this thread (and avoiding a whole new thread) I have a question:

Is there a smaller diameter grease gun coupler made to fit in tight spots such as U-joints?

 

Yes: https://www.speedwaymotors.com/Snap-In-Grease-Needle,43143.html
They work with this style zerk: https://www.speedwaymotors.com/Low-Profile-Grease-Zerks,43142.html

 

Thanks for the information. I'll get both ordered!
