50 Grease Fitting Caps Red Polyethylene

These are so much better than the generic ones with the caps that look like hats. These aren’t as easy to open but they last dramatically longer and fit so much better. Used these on my travel trailer suspension grease zerks, we used these exact ones on our aircraft (I’m an aircraft mech). Worth a little extra money to last and fit correctly.

Great Quality!!

They are caps and they fit the grease fittings. Not much else to say.

It's increasingly difficult to find well made products from the supply chain (with this site mostly dominated by China manufacturers) but I found the zerk cover caps to actually fit my tractor grease zerks. They've been on a month and I've noticed some fading of the red color in the plastic which didn't happen for about a year in the old US made ones so I'm sure they skipped the UV protection. But they were 20% if the price of the US ones so with a packet of 50 I can have a couple of years of replacements.

Bought bag of 50. After 3 years still on the same 6 I installed after the purchase. These zerk caps are good quality. Highly recommend

These will work in most recessed installations, larger ones will not. They tear easily and fade in the sun. I tried other types but they all had issues, at least these work for me and I just keep a quantity of spares and think of them as somewhat disposable.

These are the ones I use on aircraft to cover the zerts.

What I needed!
