Sight Glass Manufacturer
Encole designs and manufactures sight glasses for high pressure and high temperature. We design sanitary sight glasses for the 3-A Standard, as well as per PED protocols and explosion ATEX Standards. Encole also supplies custom sight glasses in OEM relationships.
Sight glasses can be manufactured from ultra-high vacuum to pressures in excess of 25,000 psi. Pressure ranges are determined by glass sealing method into the housing; housing design; housing material, and glass material and thickness.
All sight windows/sight glasses undergo rigorous testing procedures including: thermal cycling; pressure cycling; and helium leak check down to 2x10-10mbar-l/s - when required.
