Frequently Asked Questions: en856 4sh
Q1. What material is used for the inner tube of en856 4sh hoses?
A1. The inner tube is crafted from high-grade oil-resistant synthetic rubber, typically NBR (Nitrile Butadiene Rubber) or EPDM (Ethylene Propylene Diene Monomer) in select applications. This ensures low fluid permeability and long chemical durability.
Q2. What are the recommended installation standards for en856 4sh hoses?
A2. Installation should conform to ISO 4413 (hydraulic systems safety), with attention to minimum bend radius, proper support clamps, and avoidance of torsional stress during fitting.
Q3. How does en 856 4sh differ from 4SP and 2SN hoses?
A3. en 856 4sh offers higher spiral wire reinforcement (4 spiral layers vs 4SP’s lower wire tensile grades, and 2SN’s 2-braid construction), superior impulse life, and is rated for higher pressure applications—ideal for cyclic and pulsating loads.
Q4. What is the maximum recommended working temperature for 4sh hose?
A4. Standard 4sh hose is rated to +100°C, with premium blends tested up to +125°C. Exceeding these temperatures may accelerate aging of the elastomeric tube and cover.
Q5. Are these hoses certified for use in hazardous areas?
A5. Yes. Branded hoses like those from HydraulicHosePlus are certified to MSHA (flame resistance), ISO 18752, and achieve DIN EN856 4SH conformity, making them suitable for underground mining, shipyards, or process plants.
Q6. What tests does every en856 4sh hose undergo before shipment?
A6. Hoses are subjected to visual inspection, measurement, hydrostatic pressure (proof/burst), electrical continuity (for anti-static specs), and impulse cycle testing per ISO 1402 and ISO 6803.
Q7. What is the typical lead time and warranty for en856 4sh customized orders?
A7. Typical delivery is 21-28 days ARO, with a comprehensive 18-24 months warranty covering manufacturing and material defects.
