طقم حلقات O-Ring

Wasn't sure which size I needed for my old faucet, so having all five options in one little set saved me a trip back to the store. The 2x26mm ring seated perfectly and the rubber feels thick enough to actually last.

The 1.78x26.70mm size fit my filter housing perfectly, no leaks after a week. Three rings in the pack means I've got spares for next time, which is nice.

Bought these for a small repair job and was pleasantly surprised by how precise the fit is—the 1.78x26.70mm slid on perfectly for my application. Having five distinct thicknesses in one pack means I finally stopped guessing and just grabbed the right one.
