High-pressure grade couplings are widely adopted for high-rise building and petrochemical fire systems.

With the upgrade of global fire safety standards, high pressure 2.5MPa and 4.0MPa fire couplings are in great demand. These heavy-duty couplings are specially designed for high-rise buildings, petrochemical plants, industrial parks and long-distance water supply. All our high-pressure couplings pass strict burst pressure test and sealing test, ensuring safety under extreme working conditions. We provide complete high-pressure coupling series in brass, aluminum and stainless steel materials.
