Bulkar No. 6502 Heat-Resistant and Steam-Resistant Gasket Selection Guide

The true value of the black sheet! A special heat-resistant grade designed to overcome the weakness of "hardening degradation due to heat above 100°C."

"When we used a standard gasket on the steam line, it hardened immediately and started leaking." "I want to extend the maintenance cycle around the boiler." To address these urgent issues, especially in environments involving high-temperature steam and hot water, the high-performance joint sheet developed by Vulcan Corporation is the "No.6502 Black Hyper." In this article, we will thoroughly explain why No.6502 has gained immense trust in harsh hot water and steam lines, covering the material technology that supports its performance, the tightening management that must be strictly adhered to for safe use, and the response to special processing, all from a professional perspective. *For detailed content of the column, please refer to the related links.
