Types of sight glass discs for sale

Are you looking for an option that can handle molding temperatures or a standard model? The glass discs for sight for sale can withstand excessive heat and harsh chemicals, keeping your viewport clear under extreme conditions:

• Borosilicate pieces. Made of heat-resistant borosilicate glass, they remain intact and functional at temperatures up to 300°C. They come in 57 sizes, with or without a wiper hole, and can be customized to your specifications if you require a non-standard size.
• Aluminosilicate options. This range includes products for higher heat applications (up to 375°C). Their perfect shock resistance allows for quick temperature changes without cracking. You can buy glass discs for sight gauges in the same range of standard and custom sizes as their borosilicate counterparts.
• Quartz discs. The winner of extreme temperatures, quartz pieces are unbeatable for resisting up to 1100°C without softening or changing shape. This allows quartz options to provide a clear field of vision into high-temperature systems like furnaces, kilns, boilers, and reactors.
• Soda lime products. Buy sight glass discs made of soda lime if you need to handle processes exposed to up to 120°C. They also come with or without a wiper, providing a good view of your flows. They stand up well to chemical exposure and physical stresses.

As a premier sight glass disc manufacturer, we can engineer all enclosures with ground and polished edges to make them smooth for enhanced safety and handling. Regardless of the material, all discs undergo a controlled heating and cooling process to increase impact resistance and durability.
