Is the 90° DN9 Brass Quick Coupling Socket with Hose End – TST 090 Series suitable for steam and hot oil applications up to 200°C?

Yes. The 90° DN9 Brass Quick Coupling Socket with Hose End – TST 090 Series is suitable for steam and hot oil applications up to 200°C when fitted with Viton sealing. It is engineered for demanding industrial use, supports a working pressure up to 25 bar, and its brass body and stainless steel internals provide durability and corrosion resistance for high-temperature fluid transfer.

Can the 90° DN9 Brass Quick Coupling Socket with Hose End – TST 090 Series be used safely with abrasive or chemically aggressive fluids, and what sealing materials are recommended?

The 90° DN9 Brass Quick Coupling Socket with Hose End – TST 090 Series is built for demanding industrial use and is broadly compatible with many fluids, including water, hot oil and steam, thanks to its brass body and stainless steel internal parts. However, its suitability with abrasive or chemically aggressive fluids depends primarily on the specific chemistry and abrasiveness: - Abrasive fluids: The brass body and stainless steel balls/spring offer good mechanical durability, but highly abrasive media (containing hard particulates or slurry) will accelerate wear of sealing surfaces and internal components. For continuous exposure to abrasive slurries, consider frequent inspection/replacement intervals or specialized couplings designed for slurry service. - Chemically aggressive fluids: Compatibility depends on the fluid’s corrosiveness toward brass and stainless steel and on the seal material. The coupling’s maximum temperature rating reaches +200°C only when fitted with Viton (fluoroelastomer) seals, which also provide excellent resistance to many oils, fuels, hydrocarbons and many chemicals. For aggressive acids, strong bases, chlorinated solvents or ketones, Viton may be inadequate — alternative seal materials (e.g., PTFE/Teflon, EPDM, FFKM) should be specified based on the exact chemical compatibility. Recommended sealing guidance: - Viton (FKM): recommended for high temperature (up to ~200°C) and good resistance to oils, fuels and many chemicals. - PTFE (Teflon): best for broad chemical resistance and low friction; suitable where maximum chemical inertness is required (check temperature/elasticity needs). - EPDM: good for hot water/steam and some alkaline media but poor with oils and hydrocarbons. - FFKM (perfluoroelastomer): premium choice for highly aggressive chemicals and high temperature, though costly. Always verify compatibility by consulting chemical compatibility charts and testing under actual temperature, pressure (≤25 bar) and service conditions. When in doubt, contact the manufacturer with the exact fluid composition and operating parameters to select the optimal seal material or a more suitable coupling.
