Valued Customer,

Cashco, Inc. has released the new Model 6K00. The Model 6K00 is a weight loaded pressure / vacuum vent with integrated flame arrestor. It is designed for use on atmospheric and low-pressure storage tanks where pressure and vacuum relief is required. The design includes a deflagration flame arrestor consisting of a crimped SST metal element which allows the flow of gases or vapor of flammable liquids but prevent the flame-transmission from the outside.
