Circular sight glass fitting type 323 PN 10/25

Product information

The ACI sight glass type 323 is a variation of type 321, designed for an expanded range of applications, especially at higher temperatures. They serve to observe and illuminate the interior of sealed containers (container, boilers, tanks, silos, etc.).

The PTFE-coated corrugated ring gaskets typically used in type 321 are no longer reliably usable above a temperature of 200 °C. To eliminate this disadvantage, we use high-quality graphite composite seals in type 323, so that the operating range of the borosilicate glass plates according to DIN 7080 can be fully utilized up to 280 °C, or even 320 °C with a mica disc.

Even at temperatures above the limits of DIN 7080, type 323 can be used without problems with untempered borosilicate glass plates up to 400 °C. For higher temperatures, please inquire.

With the sealing in the force shunt, type 323 offers you the same advantages as our proven type 321. Here, too, the glass plate is best protected over the entire circumference, and the fitting can be easily installed or exchanged as a single component. The fitting is completely assembled at the factory and can, upon request, be tested for pressure resistance and tightness, so you can rely 100% on our quality.

Like type 321, type 323 can also be supplied with LED lighting upon request.
