Some helpful tips to make your o-rings last longer

---

• Put a very light coat of synthetic marker oil or grease on the o-ring periodically for a better seal and less friction.
• When removing your tank, do not simply unscrew the tank from the ASA - we recommend threading the tank off until you hear the gas bleeding through the tiny hole at the bottom of the ASA. Once bled, then you can thread the tank off, which will cause no sudden pressure damage on your O-ring. Otherwise, you might find that your fitted O-ring, after some time, will appear ruptured or elongated beyond its ability to return to its original dimensions.
