Fastul R2AT Hydraulic Hose Overview

Fastul R2AT hydraulic hose is a two-wire-reinforced hose for selected hydraulic fluid-power applications. The existing product information identifies DIN EN 853 2SN, a synthetic-rubber tube, two layers of high-tensile steel-wire reinforcement and an abrasion- and ozone-resistant synthetic-rubber cover.

DIN EN 853 2SN Identification

Confirm the size-specific data sheet

The 2SN or R2AT designation identifies a hose family, not one pressure rating for every bore size. Verify the hose marking, manufacturer data, applicable standard edition, working pressure, minimum bend radius, outside diameter and impulse requirements for the selected size.

Two-Layer Steel-Wire Construction

Published tube, reinforcement and cover

The listing describes a synthetic-rubber tube resistant to hydraulic fluids, two layers of high-tensile steel-wire reinforcement and a synthetic-rubber cover intended to resist abrasion and ozone. Actual compatibility depends on the fluid, additives, concentration, temperature and surrounding environment.

Temperature and Fluid Review

Continuous and peak limits are different

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

Pressure, Flow and Bend-Radius Selection

Provide normal working pressure, relief setting, surge or impulse conditions, required flow and hose ID. Route the assembly within the documented minimum bend radius, avoid tight bending behind ferrules and allow for movement without twist or tension.

Compatible Fittings and Crimp Specification

Use a validated hose, insert, ferrule and crimp combination for the exact Fastul R2AT series. Do not mix components unless the assembly system is approved for that combination. State both end-connection standards, orientation, overall length and any sleeve or abrasion-guard requirement.

Installation, Inspection and Replacement

Protect the hose from sharp edges, heat, impact and rubbing. Inspect for leakage, cover damage, exposed wire, corrosion, kinking or fitting movement. Never check a pressurised hydraulic leak by hand, and isolate accumulators and stored energy before inspection or replacement.

Frequently Asked Questions

Does every R2AT hose have the same pressure rating?
No. Working pressure and bend radius vary by size and manufacturer data.

Can R1AT fittings automatically be used on R2AT hose?
No. The fitting and crimp system must be validated for the exact hose construction.

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