C95800 Nickel Aluminum Bronze pipe fittings instrumentation

Detailed Product Introduction

This series of high-precision instrument-grade pipe fittings, multi-port connectors, and filtration units is manufactured from ASTM B148 C95800 Nickel Aluminum Bronze. Renowned for its outstanding structural integrity and remarkable resistance to pitting and bio-fouling in brackish water and saltwater environments, this component group is ideal for offshore oil rigs, shipbuilding, desalination plants, and chemical processing lines. The line includes high-pressure double-ferrule male connectors, four-way female crosses, full-coupling sockets, and compact in-line fluid strainers, all machined with precision CNC threads (such as 1/2" NPT) to guarantee bubble-tight seals and reliable flow management in high-salinity automated systems.
