                                                                                RECOMMENDED FOR:
Petroleum and water base hydraulic fluids in suction lines or in low pressure return lines. Small bend radius is an advantage in installations where space is minimal. (Tighter Bend Radius than SAE 100R4)
PERFORMANCE:
Meets or Exceeds the Performance Requirements of: AS 3791 100R4, SAE 100R4.
TUBE:
Black, oil resistant synthetic rubber.
REINFORCEMENT:
Textile reinforcement with spiral wire to prevent collapsing.
COVER:
Black, oil resistant and abrasion resistant synthetic rubber.
TEMPERATURE RANGE:
From -20°C to +82°C (-4°F to +180°F). For water, emulsions etc. see page 58.
WORKING PRESSURE:
Maximum working pressures are based on 4:1 safety factor (maximum working pressure to minimum burst pressure).
THIRD PARTY APPROVALS:
ABS, DNV-GL, LR, MED, USCG, DOT, GOST-R, BV, RINA and KR.
COUPLINGS:
Working pressure shown is for hose performance capabilities. Performance of a hose assembly depends on couplings used.
1.For Suction Applications, and Low Pressure Delivery (up to 25% of Maximum Working Pressure).
33000 SERIES COUPLINGS WITH RSC CLAMP
33000 Series (sizes -12 to -32) pages 334 to 338
3300 Series Couplings require a suitable clamp around the outside of the hose. Refer to RYCO RSC Clamps shown below. Assembly instructions pages 481
2.For Suction Applications, and High Pressure Delivery (up to 100% of Maximum Working Pressure).
NON-SKIVE ONE-PIECE CRIMP
T4000 Series (Sizes -12 to -32) pages 234 to 250. Assembly Instructions pages 478.

    NOTE: For sizes -20, -24 & -32, use RYCO SRF Hose.
*Due to the manufacturing tolerance on outside diameter of the hose and the range of adjustment of the clamp, it is necessary to confirm correct clamp at time of assembly.
