Is the Stainless Steel Pressure Sleeve, FM Type compatible with standard metric compression fittings and nuts?

Yes. The Stainless Steel Pressure Sleeve, FM Type is designed specifically to sit inside the nut of metric compression fittings and to compress the metric pipe against the fitting body. Manufactured from AISI 316 stainless steel, it provides precise alignment, reliable sealing under high pressure, corrosion resistance, and long service life—making it fully compatible with standard metric compression fittings and nuts used in industrial, marine, chemical, and food-processing systems.

Can the Stainless Steel Pressure Sleeve, FM Type withstand prolonged exposure to corrosive chemicals and saltwater without performance loss?

Can the Stainless Steel Pressure Sleeve, FM Type withstand prolonged exposure to corrosive chemicals and saltwater without performance loss? Yes. The Stainless Steel Pressure Sleeve, FM Type is manufactured from premium AISI 316 stainless steel, a material specifically chosen for its exceptional corrosion resistance. AISI 316 contains molybdenum, which significantly improves resistance to pitting and crevice corrosion in chloride-rich environments such as seawater, and it performs well against many common corrosive chemicals found in industrial processes. The sleeve’s robust construction and precision engineering ensure it maintains a tight, durable seal and consistent alignment under high pressure, reducing the risk of degradation-related leaks or performance loss. Caveats: While AISI 316 is highly resistant, very aggressive chemicals (strong acids, chlorides at elevated temperatures, or specialized industrial solvents) and extreme operating conditions can still cause corrosion over time. For continuous exposure to highly aggressive media or unusually severe environments, verify chemical compatibility for specific fluids, temperatures, and concentrations, or consider higher-alloy materials (e.g., duplex stainless steels, Hastelloy) or protective coatings. Proper installation, regular inspection, and maintenance will also help preserve long-term performance.
