BLACK BEAR SHEET PACKING 



THE FOLLOWING TESTS ARE INTERESTING: 



A piece of "Black Bear" Sheet Packing 

 was packed in a joint with a steam gauge 

 attached to indicate the heat. At 330 de- 

 grees for nine hours each day, taking out the 

 I'acking for examination every night, replacing 

 it the next morning, for a series of twelve 

 days — 108 hours in all — " Black Bear" Sheet 

 Packing was scarcely affected. A high grade 

 Red Packing under the same test burned to 

 a char at the end of the first day. Heat 



does not seem to affect "Black Bear" Sheet 

 Packing. 



A piece of "Black Bear" Sheet Packing 

 was boiled in oil for nine hours, and came 

 out strong and full of vitality at the end of 

 this trying ordeal. 



A piece of "Black Bear" Sheet Packing 

 has been immersed in kerosene oil for several 

 weeks, and is still in good condition. Oils do not 

 seem to affect "Black Bear" Sheet Packing. 



* ' Black Bear ' ' Steam Hose is made of the same material. Withstanding these 

 tests we need not tell you, nothing could be better for a Steam Hose.
