Engineered and tested to perform in the worst playing conditions, the Exalt burst disks are available in all relevant pressure ratings and available in convenient individual, combination and multipacks to fit your needs. ALWAYS HAVE A CERTIFIED AIRSMITH INSTALL THESE OR PERFORM ANY REPAIRS TO YOUR AIR TANK. SERIOUS INJURY OR DEATH CAN OCCUR IF INSTALLED INCORRECTLY (LIKE USING THE INCORRECT / HIGHER PRESSURE RATED BURST DISK TO REPLACE WHERE A LOWER PRESSURE RATING IS NEEDED)
