                                                                                                 RECOMMENDED FOR:
Extra high pressure hydraulic oil lines in applications where the hose cover is subjected to abrasion. Compact dimensions and small bend radius are advantages in installations where space is limited.
PERFORMANCE:
Exceeds the Performance Requirements of:
EN 857 Type 2SC, ISO 6805 Type 1 & Type 2, ISO 6805 Type 4 (sizes -10 and above), ISO 11237 Type 2SC.
CONSTRUCTION:
RYCO Proprietary DK2D design.
TUBE:
Black, oil resistant synthetic rubber.
REINFORCEMENT:
Two braids of high tensile steel wire.
COVER:
DIEHARDTM Black, oil, ozone and extra abrasion resistant synthetic rubber. Flame Resistant, Anti-Static (FRAS) & MSHA compliant. Highly visible layline branding for easy and permanent identification. No skiving required with T2000 Series Crimp Couplings.
FEATURES:
The very high abrasion resistant properties of the cover, combined with the extra high working pressures and excellent impulse life, results in increased service life and minimises equipment downtime.
Compact dimensions and small bend radius are advantages in installations where space is limited.
FRAS - FLAME RESISTANCE AND ANTI-STATIC:
DIEHARDTM complies with Flame Resistant and Electrical Resistance (Anti-Static) requirements of Australian Standard AS 2660 and Methods of Test AS 1180.10B and 13A, and requirements of ISO 6805 when tested in accordance with ISO 8030 and ISO 8031.
Meets Flame Resistant Designation “U.S MSHA” of the US Department of Labour, Mine Safety and Health Administration.
TEMPERATURE RANGE:
From -40°C to +100°C (-40°F to +212°F).
WORKING PRESSURE:
Maximum working pressures are based on 4:1 safety factor (maximum working pressure to minimum burst pressure).
COUPLINGS:
NON-SKIVE ONE-PIECE CRIMP
T2000 Series (sizes -04 to -06) pages 188 to 233. Assembly Instructions pages 478.
Not suitable for use with field attachable couplings.
