Free-Floating Piston Valve Advantage:

Unlike traditional twisting piston valves, Mastercool's free-floating piston valves move straight in and out, resulting in less wear and tear, longer service life, and more reliable sealing over time.

Maintenance:

• Check gauge accuracy annually
• Replace O-rings if leaks develop
• Keep valves clean and free from debris
• Store in protective case when not in use

Professional Quality: Mastercool brass manifolds are built to professional standards for accurate, reliable performance in demanding HVAC/R service environments.
