High tolerance to friction, Engineered for a perfect grip on the nozzle.

The thinner oring goes first into the oring pocket.

The larger oring goes after the thin one and sits above it.

The end of the nozzle that will be grabbed, the orings and the oring pocket, must be 100% dry and free from any grease or slippery compounds.

Make sure you clean it all very well for example with IPA Alcohol or brake cleaner for a bone dry surface before inserting the orings.

The kit includes one of each orings like shown in the picture.
