60 psi isn't enough for a real explosion*, but I can recall at least one such design failing after a few rough matches--team 22 used a cylinder as a support last year, and had it come apart on them. Granted, they put a lot more load on it by design--but in a collision, you're certainly asking for damage.
What about putting a PVC tube or an aluminum extrusion around the cylinder?
*Provided we're talking about a clean fracture, and the relatively large and heavy gripper coming off--if this were something that could produce shrapnel (which it isn't), 60 psi would be much more hazardous.
