Fastul R1AT Hydraulic Hose Overview

Fastul R1AT hydraulic hose is a single-wire-reinforced hose for selected hydraulic fluid-power applications. The existing product information identifies DIN EN 853 1SN, a synthetic-rubber tube, one layer of high-tensile steel-wire reinforcement and an abrasion- and ozone-resistant synthetic-rubber cover. Selection must be based on the exact hose size and assembly conditions.

DIN EN 853 1SN Identification

Standard designation is only one part of selection

The listing identifies the hose as DIN EN 853 1SN. Buyers should confirm the hose marking, manufacturer data, size-specific working pressure, minimum bend radius, impulse requirements and applicable edition of the standard. The R1AT or 1SN description does not provide one universal pressure rating for every bore size.

Tube, Reinforcement and Cover Construction

Published construction details

The inner tube is described as synthetic rubber resistant to hydraulic fluids, with one layer of high-tensile steel-wire reinforcement and a synthetic-rubber cover intended to resist abrasion and ozone. Compatibility still depends on the exact hydraulic fluid, additives, concentration, temperature and environmental exposure.

Temperature and Hydraulic Fluid Review

Confirm continuous and peak temperature limits

The existing information lists a temperature range of -40°C to +100°C and a maximum value of 120°C. The meaning and permitted duration of the maximum value must be verified from current manufacturer data. Elevated temperature can reduce hose life and allowable pressure and can affect seal and fitting materials.

Pressure, Size and Bend-Radius Selection

Working pressure generally varies by hose inside diameter. Confirm normal pressure, relief setting, surge or impulse conditions, required flow and hose size. Route the assembly within the documented minimum bend radius and avoid bending immediately behind the ferrule.

Hose Ends and Assembly Review

A safe hydraulic hose assembly requires a compatible hose, ferrule, insert and crimp specification. Do not mix components unless the assembly system is validated for that combination. Provide end-fitting type, thread or flange standard, orientation, overall length and any protective sleeve or abrasion guard requirements.

Installation, Inspection and Replacement

Install without twist, tension, kinking or rubbing against sharp surfaces. Allow for machine movement and pressure-induced length change, protect the hose from hot surfaces, and inspect for cover damage, exposed reinforcement, leakage, corrosion or fitting movement. Depressurise stored hydraulic energy before inspection or replacement.

Frequently Asked Questions

Does every R1AT hose have the same working pressure?
No. The size-specific rating and manufacturer data must be checked.

Can it be used continuously at 120°C?
Do not assume so. The listing shows 120°C as a maximum value; permitted duration and pressure derating require confirmation.

What information is needed for a quotation?
Provide hose ID, length, hydraulic fluid, pressure, temperature, end connections, orientation, movement, quantity and any protection or testing needs.
