Dynamic pressure 25 MPa, static pressure 40 MPa. Bend cycle life >1,000,000 (SAE J343). Temperature range: -54°C to +121°C (peak 150°C).

♦ Fluid Compatibility

Resistant to phosphate ester fluids (e.g., Skydrol LD-4) and aviation hydraulic oils. Chemically inert per ASTM D471.

♦ Environmental Suitability

Salt spray- and humidity-resistant for aerospace, marine, and mobile hydraulics. Complies with SAE 100R5, MSHA/OSHA standards.

FAQ

1. Which fluids are compatible with hydraulic hoses?

They are compatible with mineral oil, synthetic esters, polyglycols, HFD-R, HFD-S, HFD-U, and biodegradable fluids.

2. What is the difference between 1-wire and 2-wire hydraulic hoses?

1-wire hoses are suitable for lower pressure systems; 2-wire hoses offer higher pressure capacity and durability.

3. What does SAE 100R1 or R2 mean?

These are SAE standards that define hose construction, performance, and pressure ratings for hydraulic hoses.

4. Can hydraulic hoses be used with water or air?

Some types are compatible with water-glycol fluids; however, they are not typically designed for air unless specified.
