Cold weather may crack locktal tubes!!!

I'm finishing repairs on a radio that uses locktal tubes. I replaced one that went bad adeveloped a crack on side. Today I went and put new tube in and another one went bad same way! Keep these tubes out of cold storage above 40F. Tubes ran a long time while hot, the glass these are made of are of minimal thickness and I don't think can handle thermal stress of cold.
