Saftey Flange stripped out

Bought the zepher kit and the threaded safey flange stripped and flew off the buffer after 10 minutes. Bought another set of flanges and the same thing happened. This time I ordered the set with a nut and washer, hope it works. Frustrated having to wait on the products to be shipped.

The red ones are bomb!

Did just what I needed, where have you been all my life?!?

Mark (Durham, US)
Unable to tighten

Don't know what I am doing wrong but I can't get the safety flanges to tighten. I've followed the instructions that come with product and watched a couple YouTube videos and still can't get them tight.

What else could be going wrong?

Hi Mark,
Wanted to go over the basics with you in case there was any confusion. There's two logos on the flanges, one on each side of the safety flange. The unthreaded flange side should go on the angle grinder face, with the logo facing towards the grinder. Then the airway buffing wheel, and finally the threaded half should go last on the grinder's shaft with the logo facing outwards. The last half of the safety flange is threaded, so it should tighten as you continue to thread onto the the angle grinder shaft.

Please reach out to us at if you find yourself having any further issues or concerns.

Lots of options for polish, I always come back to zephyr.

I’m not a pro, but the results the airway pads and polish speak for themselves.

I have not been let down by zephyr products and I will continue to spend my hard earned money with them. Great shipping times, great products, fair prices.

safety flanges

I have had the same problem of the threads stripping out... mine was caused when my wheel caught an edge and jerked the buffer. The only thing is the fins on the plates themselves, got a little close with mine fingers, thankfully I had the proper ppe on, otherwise i've wore them out even tho I run 3 buffers with different wheels on them for the process I use depending on what I am polishing,wheels,tanks,steps etc...Thank you to the staff at Zephyr.

New safety flange

After buying the new safety flanges for the airway buffing wheels I had an issue with the plastic threaded flange stripping out. After only a short time of use I would recommend the old style personally. Love all the zephyr products they work awesome for all your polishing needs!

Safety flanges

Nice that they are made out of a composite material so if you slip up and hit the surface your polishing it won’t put a massive scratch but at that same time you slip up, they are now junk, it will rip the threads right out of the flange and now they are useless, would be better if Threads were a different material.

Plastic hole wears out

I have went through two sets of these and they end up rounding out the hole on the inside flange. Then creates vibration when running the pad. I ended up letting the smoke out of my cheaper angle grinder. Don't waste your time with the plastic safety flanges. Purchase the aluminum ones.
