NATIONAL 8M

POLYESTER DOUBLE JACKET HOSE MINING HOSE

8M mine hose is a premium quality rubber lined, double jacket hose that is MSHA (Mine Safety & Health Administration) approved (USMSHA No. 2G- 15/1) for the rugged demands of underground fire fighting. 

A high quality polyester reinforced outer jacket protects an inner polyester jacket and rubber liners from wear and puncture while also helping to prevent kinking that limits flow. The all polyester double jacket construction provides maximum cut and abrasion resistance and is ideally suited for mining operations.
