Whether you’re in automotive racing, heavy machinery, or hydraulic systems, understanding the capabilities of the XRP HS 79 hose ensures optimal performance and safety. This guide explores its technical specifications, diverse applications, installation best practices, and maintenance protocols.

What is the XRP HS 79 Hose?

The XRP HS 79 is a high-pressure, high-temperature reinforced hose designed for critical fluid transfer tasks. Featuring a robust construction with synthetic rubber compounds and multiple textile/steel braid layers, it excels in environments where standard hoses fail. Its compatibility with fuels, oils, and hydraulic fluids makes it a versatile choice across industries requiring leak-proof reliability under stress.

Key Technical Features and Specifications

Pressure Rating: Withstands continuous pressures up to 3,000 PSI (burst pressure exceeding 12,000 PSI)
Temperature Range: Operates flawlessly from -40°F to +300°F (-40°C to +150°C)
Reinforcement: Triple-layer braid construction (2 textile + 1 high-tensile steel wire) for maximum burst resistance
Inner Tube: Nitrile rubber compound resistant to abrasion, ozone, and most petroleum-based fluids
Cover: Abrasion-resistant synthetic rubber with SAE 100R17 specifications

Top Industrial Applications

The XRP HS 79’s rugged design caters to sectors where failure isn’t an option:

High-Performance Automotive: Fuel lines, oil coolers, and turbo systems in racing vehicles
Hydraulic Machinery: Excavators, presses, and agricultural equipment requiring flexible high-pressure lines
Marine Engineering: Engine rooms and hydraulic steering systems exposed to saltwater corrosion
Aerospace Ground Support: Fuel transfer and hydraulic servicing units

Installation Best Practices

Measure Twice: Cut hose slightly longer than needed to accommodate bends without kinking
Clean Connections: Wipe fittings with lint-free cloth to prevent contamination
Avoid Sharp Bends: Maintain bend radius ≥5x hose diameter to prevent internal damage
Secure Properly: Use cushioned clamps every 12-18 inches to minimize vibration wear
Pressure Test: Conduct a 150% operational pressure test before full deployment

Maintenance and Troubleshooting Tips

Inspect for abrasions, bulges, or discoloration monthly
Replace immediately if outer cover shows cracks or exposed reinforcement
Flush systems biannually to remove particulate buildup
Store coiled in UV-protected areas away from ozone sources
Use protective sleeves in high-abrasion zones

Frequently Asked Questions

Is the XRP HS 79 compatible with ethanol-blended fuels?

Yes, its nitrile inner tube resists degradation from ethanol (up to E85) and methanol blends commonly used in performance applications.

Can it handle synthetic hydraulic fluids?

Absolutely. The HS 79 is tested with MIL-H-5606, Skydrol®, and phosphate ester fluids without swelling or hardening issues.

What distinguishes it from standard hydraulic hoses?

Its triple-braid reinforcement and specialized compound provide 40% higher impulse fatigue resistance and superior flexibility at low temperatures compared to SAE 100R1/R2 hoses.

How often should replacement occur?

Under normal conditions, replace every 5 years. In extreme heat/vibration environments, inspect annually and replace at 3 years.

Are custom lengths available?

Most distributors offer custom cutting and crimping services with certified fittings for specific project requirements.

Why Choose XRP HS 79 for Critical Systems?

Beyond specifications, the HS 79 delivers operational confidence. Its construction minimizes permeation (reducing vapor emissions by 70% vs. standard hoses) while its flexibility simplifies routing in cramped spaces. For engineers prioritizing safety compliance, longevity, and total cost of ownership, this hose represents a smart investment in system integrity. Always verify manufacturer certifications and match fittings to your pressure ratings for optimal results.
