Although two or more hoses manufactured to different industry standard specifications may have identical Maximum Working >2

Pressures, their suitability for the application must be considered. An important factor to consider is the magnitude and 3

frequency ofthe pressure impulses that the hose assembly will experience. 3


All RYCO Hoses lexcept RYCO J5, T3600C, Hsoooc. M1, MP1, PWZ. Tw1. TP1. TP7N, TP7T, TP7TN, TP8, TPBN, TPBT, TPBTN, ‘

TP3000. RQP5. SRX. SRF. T5. RTH1 84 PL1 Series) meet Flame Resistant Designation "U.S. MSHA” of the U.S. Department of

Labor, Mine safety and Health Administration and also comply with Flame Resistant requirements ofAustralian Standard As

2550 and Method ofTest As 1130.103. contact RVCO Technical Department for more information.


Minimum Bend Radius figures published are the radius to the cover of the Hose at the inside of the bend.

RYCO Hose Assemblies exceed the required impulse test requirements when bent to the published Minimum Bend Radius.

Hose assemblies bent to smaller than the Minimum Bend Radius will have shortened lifetime.


“Anti»Static” refers to Hoses or Hose Assemblies being sufficiently electrically conductive to drain off static electricity.

According to the requirements of As 2550 clause 2.2, the Hose or Hose assembly shall have an electrical resistance

(measured from inside surface to outside surface) of less than 1 megohm per metre, when tested according to Method ofTest 3

As 113o.13A. For applications requiring Anti»Static Hydraulic Hose Assemblies including, but not limited to, underground coal E

mines, where there is danger of ignition from static electricity discharge, only special Anti-static Hose can be used. 5

RYCO DIEHARD” Hoses and coALsPRAY comply with the requirements of As 2550 and Method ofTest As 1130.1 3A. 3


certain applications require that a Hose, or Hose Assembly. be Non-conductive to prevent electrical current flow.

For applications that require a Hose to be electrically Non»Conductive including, but not limited to, applications near high

voltage electric lines, only special Non»Conductive Hoses can be used.


Skiving refers to removing the cover at the ends ofthe Hose where the Hose couplings are to be attached’. 19

Most RYCO combinations of Hose and couplings are Non-Skive. E;

In a Non»Skive application. RYCO couplings bite down through the cover and grip the wire reinforcement. 3

some combinations ofRYCO Hose and couplings require skiving. Ifskiving is required, it is clearly stated in both the Hose

section and the couplings section.

some RVCO Hose series are not listed on page 53; T1 F, TJZD. MZG. M1, RTH1. MP1. :1:

These Hoses are specific purpose Hoses, and their temperature limits are specified in the Hose section ofthis Product Technical ‘.3

Manual. Contact RYCO Technical Department for any furtherqueries. *-

other RVCO Hose series are listed on page 58.The Maximum Working Temperatures for these hoses, as listed in the Hose

section of this Product Technical Manual are for use with general purpose, mineral lpetroleum) oil based hydraulic fluids.

except where otherwise stated. Temperature limits for other hydraulic fluids, and some other common applications. are listed

on page 53.


Life expectancy of hoses is shortened at high temperatures. Detrimental effects increase when temperature is elevated, and

also when; operating pressure, flow velocity, duration and frequency of exposure, and level ofimpurities in the media are high.

Actual service life at temperatures approaching the recommended limits will depend on the particular application and the fluid

being used.

Maximum Working Temperatures refer to the temperature ofthe media in the hose; not the environmental temperature

around the outside ofthe hose. Please contact RYCO Technical Department for environmental temperatures in excess of BO“C

(1 76°F), except RQP1, non, Reps and now; Series where environmental temperature is the same as media temperature.

Maximum working Temperatures shown are for continuous temperatures. Slightly higher intermittent temperatures (up to

10% oftime) may be acceptable with some hoses and some fluids, if reduced service life is acceptable. Please contact RVCO

Technical Department for more information.

DO NOT expose Hose to Maximum Temperature and Maximum working Pressure at the same time.

The fluid manufacturer'srecommended maximum operating temperature for the fluid must not be exceeded. If different to the

temperatures listed in the following table, the lower limit must take precedence. we recommend keeping the hose filled with

the pressure medium at all times. Further information available on request.
