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.

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 ¾" 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.

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  - Only available on SS,PB,HB or KYB in sizes of ¾" and above.

Specifications  - As for the Braided Hose Graph.
