Details

Plastic Sight Glass Float Ball

This small plastic ball floats on the surface of the boiler water inside the sight glass (level gauge), giving you a quick visual read on boiler water level at a glance.

SPECIFICATIONS

  • Diameter: 6 – 6.5 mm
  • Material: plastic
  • Sold individually, one ball per purchase

COMPATIBILITY

  • Fits: sight glass tubes with an inner diameter of 6.6 mm or larger

INSTALLATION

Drop the ball into the sight glass tube — no tools required.

PRO TIPS

  • If your sight glass reading looks stuck or the ball doesn't bob with water level changes, check for mineral scale buildup inside the tube before assuming the ball itself is bad — scale is the far more common culprit.
