Overview
This Type B metal wound gasket is engineered for reliable, high-integrity sealing in demanding industrial piping systems. It is specifically constructed for use on 1-inch nominal pipe size (DN25) class 600 flanges, capable of containing pressures up to 600 PSI. The gasket's robust design combines the strength of metal with the conformability of a soft filler, creating a leak-tight seal that accommodates minor flange irregularities and thermal cycling. It is manufactured in compliance with the HG/T 20631-2009 standard, ensuring consistent quality and dimensional accuracy for interchangeability in regulated applications.
