KR - Kink Resistant

Purpose - For application where there is a risk that the hose might be severely flexed anywhere along its length and possibly kinked as a result. NOTE: The rubber cover hose has a "cloth" finish, not the very smooth finish normally available.

Design  - KR is only available on hoses, which also have a SS wire braid and a rubber cover (RC, FP or SI).  An SS reinforcement wire is helically wound on to the SS wire braid and then the rubber cover is applied on top of the helical wire.

Limitations  - Only available for sizes ½" and above.

Specification  - As per Rubber Covered hose grade, except that the standard RC grade rubber has a super smooth finish which is not possible on the "KR" hose grade.

SG - Safegard Protection Sleeve

Purpose  - To protect the hose against external abrasion and mechanical damage. For use in applications where maximum external protection is required with minimum extra hose weight. Particularly useful with PB or KYB hose, where a rubber cover is not an option.

Design  - A lightweight black, HDPE (High Density Poly Ethylene) strip spirally wound around the outside of the hose over its whole length, secured to each end fitting by crimping under a SS ferrule.

Limitations  - Safegard is applicable to all hose types, and all hose sizes from 1/2" up to 4".

Safegard is limited to use within a temperature range from -40°C (-40°F) up to +100°C (212°F). Internal fluid temperatures up to +120°C (250°F) are acceptable, when external temperatures are ambient.

The minimum hose assembly length must be doubled, if Safegard is being used.

Other hose usage limitation specifications are not altered by the addition of Safegard.

SR - Scuff Rings

Purpose - For medium duty applications where the hose requires some protection against abrasion when dragged over the ground, but where a full rubber cover would be too heavy and cumbersome.  Also for PB and KYB braided hose, which cannot be Rubber Covered

Design - Specially moulded abrasion resistant rubber scuff rings are placed every half-metre along the hose.

Limitations - Available for hose sizes 1" (25mm) to 2" (50mm) only.  The operating temperature should not exceed 140°C (internal).

PC - Protection Coil

Purpose - For applications where the hose requires protection against abrasion when dragged over the ground, but where any rubber reinforcement is not permissible due to temperature, chemicals etc.

Design - A stainless steel wire helix is wound onto the braid, and welded to the ferrules at each end.

Limitations  - Available for all sizes and grades of Bioflex Hose.

Specifications  - As for the relevant Hose Grade.
