These particular caps are manufactured in India, they are small plastic caps so how long they last will depend on the amount of use they get. Generally speaking though one package should last at least a year. Thank you **Q: Do these fit a kubota bx series zerk?** A: Hello, Thank you for getting in touch, these fit all standard grease fittings (SAE & Metric) and will work on your machine. **Q: How does the securing loop attach? Will i have to unscrew the grease plugs or what?** A: If your fittings are smaller (1/4"-28 or Metric 6x1 you can unscrew them to install the loop under the head of the Zerk. And, you also have the option of just pushing the loop over the head of the Zerk. You'll still have enough room to attach the cap on top of it and be able to secure your coupler without removing the strap. **Q: will these work as dust caps for automotive brake bleeder valves?** A: That will depend on the size of the bleeder valve. We haven't tested these on bleeder valves in the past, but if yours are M6 or M8, these should fit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A simple but effective product *by A***R on March 30, 2024* The caps are well designed to snap over zerk fittings with some effort.

All in all, a good idea at a reasonable price. ### ⭐⭐⭐⭐⭐ Securely locks on. *by K***O on November 16, 2025* Some or the best snapping lock action zero caps I have used. Used to have the thin red ones from other manufacturer. Good enough to put on and fall off once the vehicle starts moving. These LockNLube caps is quality. ### ⭐⭐⭐⭐⭐ Great caps *by C***R on July 17, 2021* I waited a bit to try these caps before posting a review. I have a John Deere 1025r tractor I thought these would be great on. These tractors have ALOT of grease fittings. These caps are flexible enough not to break, they grab the head of the fitting very well and do not pop off. I even installed them on the mower deck spindles and rotating shafts thinking that they will probably fly off or come uncapped, nope, they stay in place very well. The bright yellow color also helps visually locating the fittings quickly and not miss any. Some people just goop extra grease on the fittings to cover them but over time it makes a mess. These caps keep your fittings clean so dirt doesn't plug the fittings. You get quite a few in a pack so you'll have plenty extra though I have yet to use them all. Very useful item that I didn't originally give a thought to but very handy. ## Frequently Bought Together - LockNLube Grease Fitting Caps (50 count) (Red) - LockNLube Grease Gun Coupler locks onto Zerk fittings.
