I ordered these for use in an air suspension system with 1/4" tubing. The description says it's for 1/4, but it's not. Instead it's for 6mm tube, which is just a bit smaller than 1/4. 1/4 can be forced into it but not far enough to fully seat it.

They don't hold pressure too well. Squirted a little oil on them to get them to seal.Get what you pay for.
