Sealmax Style 904 – Aramid Staple Yarn with PTFE
Sealmax Style 904 is braided from aramid staple fibre yarn and impregnated with PTFE along with a silicon-free lubricant. The packing has a dense and robust construction, making it suitable for high-pressure and high-speed applications.
Style 904 serves as an effective replacement for PTFE-impregnated asbestos packings and performs particularly well in applications involving abrasive media due to the high strength and wear resistance of aramid fibres.
Style 904 is suitable for valves, sliders, pumps, and agitators across industries where a strong, durable, and wear-resistant packing is required.
Style 904 is designed for abrasive media and general industrial fluids.
Style 904 has economical packing which is suitable for a wide variety of applications across multiple industries.
Style 904 is not recommended for highly concentrated acids and alkalis (lyes), certain organic compounds, or alkali metals.
