Partial slit, only in the rubber leaves PTFE to form an evaporation barrier making this a good choice for volatile samples when an autosampler requires a pre-slit Septa.Y shaped partial slit allows for better "resealing" of rubber after initial injection.

Soft polyethylene caps are more pliable than other Snap Caps and are easier to place on the vial. Popular choice when using a large number of caps at one time. These caps may not seal as well as other Snap Caps and should be used with sample solvents with low volatility.
