How do I ensure a proper seal?

Ensure the O-ring is clean and properly seated in its groove before installation to guarantee maximum fluid resistance.

Can I use these for gas sealing applications?

Yes, they are reliable for fluid and gas sealing tasks, provided the pressure requirements are within the material's design limits.
