.250'' (1/4" Actual) Buna-N O-Ring Cord Stock

This is a good value for 100' of .103" o-ring cord stock! It works perfectly in our CNC'd, dovetail cut, valve cover o-ring grooves. Fits perfectly and on a roll that is easy to store on our assembly shelf. We use this in our customers cylinder heads and when they do come back in for service there is shrinkage, but that is to be expected with a rubber material. Cuts easily with an exact-o knife.

This 1/16" O-Ring Cord Stock worked great to fill the gap between a new side mirror and the mirror bezel on my classic car. As a result, the mirror looks very professionally done!

Worked great making a new plenum oring gasket for my supercharger

Mr. O-Ring always seems to have what we need in his "store" and it is just as described and for the best price around! I don't normally leave reviews but figured maybe this would give someone hesitant to buy from him the positive feedback they need to make a decision! We use this size o-ring cord in some of our cylinder heads (obviously we use multiple sizes) after we CNC a groove using a dovetail cutter.

Installed OK to replace a seal in an old all weather case.

good item

Had some clamps thag needed new orings. These worked great. No leaks! Highly recommend

I bought this hoping to use it as a weather seal for the lid of a Pelican case. The size is perfect, but it's not squishy enough to be able to use it for what I wanted - the lid will not close with the seal in place. Don't get me wrong, that's my bad, hence the 5 stars because the product is exactly what the seller says it is and it will work great for that. For anyone else looking for Pelican case seals, I learned in the process that Pelican will give you a new seal for just the cost of shipping, so if you are looking cord for that purpose, reach out to them instead.
