An upgrade to the standard GRSP, the composite version features a multi-layered construction of high-grade rubber and specialized polymers. This design is engineered to resist “permanent set” (loss of elasticity) over time. CGRSPs are ideal for environments with extreme temperature swings or very high tonnage. CGRSP 6.2mm = T-6618,T-8327 CGRSP 10mm = T-8528,T-8747,T-7010
