This document from Parker Hannifin Corporation's Parflex Division provides guidelines for selecting and using hoses, tubing, fittings, and related accessories. It emphasizes the importance of adhering to safety standards to prevent potential hazards such as high-speed fitting ejection, fluid discharge, and explosions.
The safety guide outlines general instructions for the selection and use of hoses and fittings, emphasizing the need for fail-safe system designs and user responsibility in ensuring compliance with safety standards. It also highlights the importance of distributing the safety guide to all relevant personnel.
- Electrical Conductivity: The document discusses the need for selecting hoses based on their electrical conductivity or nonconductivity, depending on the application requirements.
- Pressure: Hoses must be selected to withstand the maximum system pressure, including surge and peak pressures.
- Suction: Proper hose selection is crucial for suction applications to prevent collapse.
- Temperature: Fluid and ambient temperatures must not exceed hose limitations to avoid degradation and failure.
- Fluid Compatibility: Compatibility of hose materials with the fluid media is essential to prevent chemical reactions and ensure longevity.
- Permeation: The document warns about the potential hazards of permeation, especially with gases and fuels, and advises considering legal and safety regulations.
- Size and Routing: Proper sizing and routing are necessary to minimize pressure loss and avoid mechanical issues like kinking and twisting.
- Environment and Mechanical Loads: Hoses must be protected from environmental factors and mechanical loads that could lead to premature failure.

- Specifications and Standards: Compliance with government, industry, and Parker specifications is mandatory.
The document serves as a comprehensive guide for the safe selection and use of hoses and fittings, emphasizing the importance of understanding and adhering to safety standards to prevent accidents and ensure system integrity.
Certain fire-resistant fluids require specific types of hoses, similar to those used with petroleum-based fluids. Some fluids necessitate special hoses, while others may not be compatible with any hose. Incorrect hose selection can lead to early failure. All liquids, except pure water, can burn under certain conditions, and even water leakage can be hazardous.
Hoses can be destroyed by radiant heat from nearby hot objects, potentially causing fires. Welding or brazing near hydraulic lines requires removal or shielding of the lines to prevent ignition of escaping fluids. Atomic radiation affects hose materials, and exposure should be avoided.
Only hoses and fittings from Parker’s Stratoflex Products Division are approved for in-flight aerospace applications. Mixing components from different manufacturers is prohibited unless explicitly approved.
Inspect components for defects before assembly. Only use Parker fittings with Parker hoses unless authorized. Follow Parker’s published instructions for assembly and avoid using mismatched parts. Do not reuse fittings that have failed or been previously used.
Ensure hoses are installed without twisting and maintain the minimum bend radius to avoid reducing hose life. Secure hoses to prevent damage from flexing or pressure surges. Properly connect ports to avoid transferring twist or torque to the hose.
Regular maintenance is crucial to prevent hose failure. Inspect hoses for damage and replace them if any defects are found. Establish replacement intervals based on service life and risk potential. Handle high-pressure fluids with caution to avoid injury.
The document outlines terms of sale, payment, delivery, warranty, and limitation of remedy. Payment is due within 30 days of delivery, and the warranty covers defects for 365 days or 2,000 hours of use. The seller’s liability is limited to repair, replacement, or refund, with no liability for incidental or consequential damages.
