Due to the fact that a large number of our customers do not return their cores (which depletes our inventory and cannot be re-plated for the next customer), we require you to Send Your Core to us before we release your order. Please make sure it is NOT sleeved (if it is, we will not be able to fulfill your order). Please remove to ALL fittings including studs, power valves, etc. as our cylinders are shipped completely bare.
