12. FAQ – Expert Answers for Technical Specification & Industry Terms

Q1: What material is used for the reinforcement layer in rubber air hose 3 8?
A1: High tensile steel wire braid is typically used, especially for hydraulic and pneumatic lines requiring burst pressure above 9000 psi. For lighter duty, polyester yarns are also common.
Q2: What are the fitting options for rubber air brake hose fittings?
A2: Options include push-on, crimp, reusable, threaded, and quick-coupler designs. DIN, SAE, ISO standards govern sizing; always verify compatibility with tube material & application pressure.
Q3: How is the bend radius defined for hoses like 3 4 inch rubber hose?
A3: Bend radius is the minimum arc the hose can achieve without kinking, measured in millimeters. For a 3 4 inch rubber hose (DN19), it’s ~120mm for standard rubber and lower for steel-braided variants.
Q4: How does a heat resistant rubber hose maintain performance at high temperatures?
A4: By using premium-grade EPDM or silicone, plus specialized cross-linking and vulcanization processes. These allow continuous service at 150°C+ while retaining flexibility and burst resistance.
Q5: What installation standards apply to 1/4 rubber air hose and 1/2 id rubber hose?
A5: INSTALLATION must follow ISO/TS 17165-2 guidelines (20% bend radius over min, secure clamps, avoid tensile stress at connections). Use only fittings rated above the working pressure.
Q6: What periodic inspection is recommended for power steering rubber hose?
A6: Inspect for swell, blister, abrasion, and coupling slippage every 6 months. Replace hoses showing >10% diameter change or microcracking.
Q7: Can I use a braided rubber hose for both air and chemical transfer?
A7: Many braided rubber hose assemblies support both, but check for chemical compatibility per ISO/TR 7620. For aggressive media, choose a fluoropolymer or special rubber lined variant.
