Does anyone have an idea on how long these last. and country of manufacture. the china ones i got last time maybe last six months

Hi, Thank you for your interest in our products. 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

Do these fit a kubota bx series zerk?

Hello, Thank you for getting in touch, these fit all standard grease fittings (SAE & Metric) and will work on your machine.

How does the securing loop attach? Will i have to unscrew the grease plugs or what?

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.

will these work as dust caps for automotive brake bleeder valves?

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.
