Can FM240 steel braided thermoplastic sub-ducting hose be used with hydraulic oils at temperatures above +65Â°C for continuous operation?

No. FM240 steel braided thermoplastic sub-ducting hose is rated for continuous operation up to +65Â°C only for water and air; the general operating temperature range is â40Â°C to +93Â°C, but the specification explicitly limits water and air to +65Â°C. For hydraulic oils continuous use above +65Â°C is not recommended because the hose construction (polyester inner, microâperforated polyurethane outer, steel braid reinforcement) and the stated service limits indicate potential material degradation, loss of pressure rating, or shortened service life at sustained temperatures above +65Â°C. If your hydraulic system will run continuously above +65Â°C, choose a hose explicitly rated for those temperatures or consult the manufacturer for a highâtemperature hydraulic variant or confirmation of suitability.

Is FM240 steel braided thermoplastic sub-ducting hose suitable for continuous use with fuels and oils above +65Â°C?

No. FM240 steel braided thermoplastic sub-ducting hose is not suitable for continuous use with fuels and oils above +65Â°C. The specified operating temperature range is â40Â°C to +93Â°C, but the note clarifies that for water and air the limit is +65Â°C; for fuels and oils continuous use above +65Â°C is not supported by the product specification and could risk degradation of the polyester inner layer and micro-perforated polyurethane outer layer, affecting safety and performance.

Can FM240 steel braided thermoplastic sub-ducting hose handle intermittent spikes above +93Â°C?

FM240 steel braided thermoplastic sub-ducting hose is specified with an operating temperature range of -40Â°C to +93Â°C (and for water and air up to +65Â°C). This rating defines the temperatures at which the hose materials (polyester inner layer, steel braid reinforcement, microâperforated polyurethane outer layer and welded outer layer construction) will perform reliably under normal conditions. Intermittent spikes above +93Â°C are not covered by the stated operating range. Occasional short excursions slightly above the maximum may be tolerated for very brief periods, but they increase risk of accelerated material degradation (softening, loss of mechanical properties, reduced burst/working pressure margins, embrittlement of polymer layers, compromised welded outer layer and microâperforated polyurethane). The extent of acceptable overtemperature depends on spike magnitude, duration, duty cycle and fluid type, but since the manufacturer limit is +93Â°C, any operation above that should be considered outside specification. Recommendation: Do not operate FM240 above +93Â°C without consulting the manufacturer or supplier. If your application may see intermittent spikes, provide details (peak temperature, duration, frequency, fluid) to the manufacturer for assessment, or consider a hose rated for higher temperatures to ensure safety and longevity.
