A blend of natural rubber - with high tensile and tear resistance. The lower half is the same compound as used with Dura-Seal (ORG)(45) for its excellent sealing ability, and the upper half is the same as used with Dura-Seal (60) for its cut and abrasion resistance.
 

Dura-Seal (ORG 45) - compound for optimum sealing and minimum wear on the belt
 

Dura-Seal (60) - compound for best wear and impact resistance.
 

Works Great – in abrasive and impact area conditions where cut and gauge is a problem, as seen in hard rock mining.
