Post O-rings - 10 Pack

This is a quality made o-ring made from Nitrile N70 which is a durable rubber. Nitrile is an ideal sealing compound for post o-rings as it has excellent gas barrier properties and also has good wear resistance so it should last a long time with the disconnect slipping up and down the side of it. Losing gas can be expensive and changing o-rings is cheap. For this reason it's always good to change this cheap o-ring out periodically.
