Is the PROKOMP 1SC compact hydraulic hose suitable for continuous use at +100Â°C or only for short-term exposure up to +120Â°C?

The PROKOMP 1SC compact hydraulic hose is designed for continuous operation up to +100Â°C. The specification allows short-term (temporary) exposure up to +120Â°C, but +120Â°C is not intended as a continuous operating temperature. For water and air the maximum continuous operating temperature is lower (+70Â°C). In summary: continuous use up to +100Â°C; brief, temporary excursions up to +120Â°C only.

Can PROKOMP 1SC compact hydraulic hose be used with air above 17 bar without risk if outer layer is micro-perforated?

PROKOMP 1SC compact hydraulic hose is not guaranteed safe for continuous use with air above 17 bar solely because its outer layer is microâperforated. Although the product allows microâperforation of the outer layer for air above 17 bar, safe use also depends on matching the specific hose diameter to the required working pressure (90â225 bar range), correct reinforcement (single steel braid), confirmed impulse life (300,000 cycles), and adherence to temperature limits (max +70Â°C for air). Therefore, if you use the correct diameter rated for your pressure, keep air temperature â¤ +70Â°C, ensure proper installation and maintenance, and perform any required certification/inspection after microâperforation, PROKOMP 1SC may be used; otherwise do not assume it is safe.

Can PROKOMP 1SC compact hydraulic hose be used with fluids other than oil, water, or air (e.g., glycol-based fluids)?

PROKOMP 1SC compact hydraulic hose is designed primarily for oil-based hydraulic fluids, water and air per the provided specifications. Its inner and outer layers are oil-resistant synthetic rubber and the hose meets EN 857 1SC / ISO 11237-1, with working pressures 90â225 bar and temperature ratings â40Â°C to +100Â°C (temporarily +120Â°C). For water and air the maximum operating temperature is +70Â°C, and for air above 17 bar microâperforation of the outer layer is required. Use with other fluids (e.g., glycol-based fluids) is possible only after compatibility verification because: - The inner layer is specified as oil-resistant synthetic rubber, but not all elastomers tolerate glycol/waterâglycol mixtures, brake fluids or aggressive additives. Glycols can cause swelling, softening or chemical degradation depending on compound and temperature. - Temperature and pressure limits must be respected; some glycol mixtures have different thermal and chemical behavior than oil or water. - Standards and tested lifespan (300,000 impulse cycles) apply to intended fluids; using unapproved fluids may invalidate performance and safety claims. Recommendation: - Consult the hose manufacturer or material supplier with the exact fluid formulation, concentration, temperature and pressure profile for a chemical compatibility check. - If manufacturer approval is not available, perform accelerated compatibility tests (swelling, hardness, tensile, impulse testing) or choose a hose explicitly rated for glycol/waterâglycol service.
