Differences Between Single & Double Layered Fire Hoses

The difference between single and double jacket hoses is the layers.  Simply put, double the layers means double the strength and double the lifespan.  Single jacket hoses contain a single layered polyester jacket with a rubber liner, and a double jacket hose has an extra layer of polyester pulled over it making it double the thickness.  Both have their advantages. 

• Single jacket fire hoses are suitable when you need a lightweight and more economical hose.  The working pressure is 250 PSI.
• Double jacket fire hoses are built for long term heavy abrasion.  They have double the life of a single jacket hose and have an excellent working pressure of 400 PSI. 
• Both hoses have treated polyester materials which are 100% mildew & mold immune and will never require drying; pack them away wet.
