SAE 100 R7 Hydraulic Hose: High Pressure & Durable

While both fall under SAE 100 specifications, R7 thermoplastic hoses differ significantly from traditional R1 rubber hoses. The sae100r7 uses advanced thermoplastic materials that reduce weight by 40% while increasing chemical resistance and flexibility. The reinforcement structure features a single high-tensile synthetic braid rather than multiple steel wire braids used in R1 hoses.

100r7 hose demonstrates superior compatibility with petroleum-based hydraulic fluids (ISO 32, 46, 68), biodegradable oils, high water-based fluids (HFA, HFB, HFC), and synthetic esters. The thermoplastic tube resists swelling and degradation better than traditional rubber compounds, especially with fire-resistant hydraulic fluids.

Operating within the specified range of -40°C to 93°C is essential for optimal performance. Below -40°C, the hose may stiffen temporarily but regains flexibility at normal temperatures. Prolonged exposure above 93°C reduces service life as the thermoplastic material softens beyond design parameters. Temporary peak temperatures up to 121°C are acceptable for short durations.

Installation should follow these guidelines: ensure hose length accommodates thermal expansion (+2% to +4% at max temperature); maintain bend radius ≥3x hose OD; avoid twisting during assembly; use fittings specifically designed for thermoplastic hoses with appropriate inserts; protect against abrasion at mounting points; and test at 1.5x working pressure before commissioning.

Standard service life depends on operating conditions: continuous use at max pressure/temperature requires replacement every 2 years; normal operating conditions typically allow 3-5 years; conduct quarterly inspections for abrasion, kinks, or external damage; replace immediately if cover damage exposes reinforcement; monitor for increased flexibility which may indicate internal degradation.

Most sae100 r7 hoses can handle suction applications within specified pressure ranges, but confirm compatibility with manufacturer specifications as some constructions may collapse under high vacuum. Select reinforced suction models with helix wire inserts when vacuum levels exceed 20in Hg.

Our SAE 100 R7 hoses meet or exceed SAE J517, EN 853, ISO 18752, and MSHA standards. Additional certifications include RoHS compliance and DNV GL marine approval. Documentation packages with test certifications are available upon request.
