How To Replace Plastic Bayonet Tips

How to replace the plastic bayonet tips on your AO or Randolph sunglasses:

First, you need to remove the existing plastic tips:

  1. First, use a hair dryer or warm water to warm up the plastic temples. You only need to heat them up so that they are warm and NOT hot!
  2. Next, use a pair of pliers to gently pull the old tips smoothly off the arms.
  3. Once you have the old tips off clean the temples (arms) to remove any debris, discoloration or gunk that remain on them.

Next, install the brand-new plastic bayonet tips:

  1. First, put some Windex (or soap and water) on the first part of the temple (arm).
  2. Hold the temple (arm) close to the end but further down than where the plastic tip end.
  3. Carefully slide the plastic bayonet tip onto the temple, gently twisting and pushing it until the temple is fully installed.
  4. Last, gently heat the tips again to harden them to the temples.
  5. This would be a great time to adjust the temples for a good fit to your head.

If it helps you can watch a good video on YouTube at:

I hope your replacement of these tips goes smoothly.

Keep your sunglasses clean and in good shape!

i used a heat gun on the bare metal of the earpiece which allowed the plastic to slide right on. like a hot knife thru butter. very little is needed as a heat gun is far beyond the heat of a blow dryer. i also anchored the earpiece using a vise so as to make it a one handed operation. as the metal cools and the plastic around it, a nice bond and snug fit is created. if you own a heat gun then you probably are savvy enough around the shop that you’ll be comfortable using this technique. i was done in under five minutes. my randolph’s bought in 2000 are looking like new. thanks for making this part available.

Great instructions on removing and installing plastic eyeglass temple sleeves on Randolph frame arms. Where can they be purchased?

Thank you for this tutorial. I will try to do it with my AO aviator shades.


I am retired U.S. Army and own 3-pairs of American Aviator sunglasses. All have acquired a green substance in the bayonette tips. I know how to remove and replace, however, I do not know how or where to purchase new tips.
