  • Gauge Glass Guardian

  • Description / Operation:

    Gauge Glass Guardian, sold exclusively through Keystone Steam Supplies is your safeguard against personal injury, which could be caused by the accidental breakage of tubular Gauge Glass and the leakage of steam or hot water that occurs as a result.

    Built from clear, High-Temperature Resistant (122ºC/252ºF Continuous), Shatter-Resistant, Polycarbonate Tubing, this lightweight material is an inexpensive answer to keeping you and the glass tubes protected from damage. In the event of a leak, Gauge Glass Guardian will discolour, alerting you to the fact that your system requires immediate attention. 

    Available in 2” & 2½” O.D. x 1/8” Wall, slit and de-burred into (2) half-cylinder sections, precut to your specifications; or field-cut to the length you require.  Fasten with worm-gear clamps.  ‘Gauge Glass Guardian’ is also available in larger diameters as 96” lengths only.
