Additional Details

Our 2 1/2 inch single jacket lay-flat mill hose is excellent for light industrial and construction applications where medium water pressure is used. This hose is constructed of an SBR synthetic rubber tube and a single layer of 100% polyester woven jackets.

Not intended for structural firefighting. Single jacket hoses are never used in the fire service.

How To Purchase Fire Hose

  • Adding color impregnation improves durability compared to untreated white hose
  • 50 foot lengths are easier to handle and offer more layout flexibility vs. 100 foot lengths
  • The most common hose, thread and couplings in use by fire departments today is double jacket hose with aluminum NH / NST
  • Double jacket hose with any color is the most durable hose available

Applications

  • Construction Sites

Test Ratings (Water Only With Expansion Ring Couplings)
