All CANTY sight glasses feature the Fuseview™ window. Our unique fused glass windows far exceed all conventional tempered glass windows in safety and performance. By fusing glass to metal, a high pressure, high safety, hermetic seal is formed. The fused glass Technology ensures safety with every Fuseview™. What’s more, our windows can easily be removed for cleaning. CANTY windows do not have to be discarded, as do traditional tempered glass windows. CANTY fused glass windows can be re-used again and again.

CANTY FuseView™ sight glasses have been engineered to meet all your process and safety needs. All standard FuseViews™ feature Factory Mutual approval and were designed and tested to ensure the safest product available. CANTY can provide certification of material and testing if required, typical of ASME code requirements for process vessels.
