☠ WARNING: DO NOT INTERCHANGE GASTEC PUMP OR TUBE SYSTEM WITH ANY OTHER PUMP AND TUBE SYSTEM. 

• Interchangeability refers to using a pump from one manufacturer and a tube from another manufacturer.
• The ANSI/ISEA specification #102-1990 (R1998) “Performance Standard for Detector Tube Units Used to Monitor Gases and Vapors in Working Areas” is designed to ensure that gas detector tube systems are not interchangeable. (Example: different regulator threads for gas cylinders containing different gases). 
• Interchanging parts and components of different manufacturer’s systems reduces system accuracy and reliability and may also cause system failures.
