A pressure-resistant and heat-resistant tempered glass for pressure vessel sight glass. We have a lineup of aluminosilicate glass and borosilicate glass that conform to JIS B8286 (mean coefficient of linear expansion test, bending strength test, thermal shock test).
*JIS B8286 is the standard for sight glass for pressure vessels. (JIS: Japanese Industrial Standards) Please check each country’s standards individually.
We will respond to requests for shapes (circular, square, rectangular) and sizes, etc.
Please feel free to contact us.
