STAINLESS STEEL Hydraulic Manifold Reduced Ferrule Pipe Sanitary Spool
This stainless steel Hydraulic Manifold Reduced Ferrule Pipe Sanitary Spool is a high-precision hygienic piping connector for hydraulic integrated systems, designed for seamless reduced-diameter ferrule connection of clean fluid pipelines. It features non-dead-corner polished inner wall, meets food and pharmaceutical hygiene standards, with reliable high-pressure sealing performance, widely applied in food, pharmaceutical, beverage and bioengineering industries for hygienic hydraulic fluid transfer.
Working Principles

This sanitary spool connects to hydraulic manifold and pipelines via ferrule fittings. When tightened, the ferrules deform to grip the spool’s outer wall and the fitting body, creating a metal-to-metal seal. Its reduced-diameter structure enables smooth fluid transition between different pipe sizes, while the hygienic polished inner wall ensures unobstructed, contamination-free fluid flow in hydraulic systems under pressure.
