Fused Sight Glasses

PresSure Products Company's line of DuraPort fused sight glass windows offers the superior performance, safety, and longevity your facility requires. With our DuraPort sight glasses, the outer metal ring imposes an enormous static compression on the glass--thus, any tensile load imposed on the unit in service merely serves to relieve some of the pre-loaded compression. PPC's DuraPort sight glasses also feature fracture containment, thermal shock resistance, and true Type 1 borosilicate glass.
