Spiral Wound Gasket PN16-40 316 IR 316-F-G DIN
The Spiral Wound Gasket PN16-40 316 IR 316-F-G DIN is a high performance semi-metallic seal engineered for industrial pipe systems that demand reliable leak prevention under medium-to-high pressure and temperature conditions. Rated for pressures from 16 to 40 bar and built to EN 1092 / DIN flange specifications, it fits seamlessly into standard European piping systems without modification or guesswork. Its Grade 316 Stainless Steel winding and Flexible Graphite filler work in tandem to maintain a tight, stable seal even in the harshest operating environments where heat, corrosion, and pressure fluctuations can cause lesser gaskets to fail. A dedicated 316 Stainless Steel inner ring adds structural reinforcement, preventing inward buckling and protecting the winding's integrity under load.

This gasket is a trusted choice across some of the most demanding industries. In chemical plants, it holds firm against corrosive process media and aggressive solvents. In steam and thermal systems, the flexible graphite filler resists breakdown at elevated temperatures where synthetic materials fall short. In oil, gas, and petrochemical networks, it delivers the consistent sealing performance that refining operations depend on. Water utilities and power generation facilities operating at PN16 ratings and above rely on it for long-term, maintenance-free service.

Built to exacting DIN dimensional standards, the Spiral Wound Gasket PN16-40 316 IR 316-F-G DIN offers the precision, material quality, and pressure-rated reliability that engineers and procurement specialists require when there is no margin for error.
