e. Double-jacketed hose
Double-jacketed hose is heavier and more
costly than single-jacketed hose. In
practice, some engines carry one or two
lengths of double-jacketed hose for the first
lengths in the lay to reduce excessive
losses from bursts closer to the engine.
Type: Double-jacketed, rubber-lined, with
a working pressure of 400 psi.
Construction and materials: There are
two jackets constructed of 100 percent
virgin spun polyester yarn. The liner is a
petroleum-based thermoplastic polyester
elastomer with a smooth inner surface. The
inside jacket and liner are bonded
together.
Flow rate: Friction loss relative to hose
diameters is basically the same as the
cotton-synthetic lined hose. Slight
differences may be due to the type of lining
and roughness of the inside surface of the
lining.
Weight: Weights of hoses are as follows
(weights may vary depending on
tolerance):
12 inch 38 lb/100 ft; 22 inch 68 lb/100 ft.
molded construction. This hose is
designed for use on hot fire lines with little
possibility of damage. The hose can be
wiped off with a dry rag after use. Abrasion
resistance is high and the exterior covering
is not readily damaged by the usual
solvents. High-pressure hose (w inch ID) is
available in 50-foot coupled lengths. This
category also includes booster hose, which
is not included in Specification 5100-185e.
Type: Compound rubber cover, multiple
plies yarn reinforcement, and rubber-inner
lining, with a working pressure of 600 psi.
Booster hose has a working pressure of
800 psi.
Construction and materials: Multiple
layers of braided or knit piles of cotton or
synthetic yarn are embedded in rubber
compound cover. The inner lining consists
of a tube of rubber. The lining and cover are
bonded together.

f. Rubber lined, braided high pressure
hose
Rubber-lined, rubber-covered, highpressure
hose is used as “hardline” on
engine live reels. Forest Service
specifications require a heavy-duty,
noncollapsible water hose of braided and

g. Woven fabric hardline hose.
This hose is used as an initial attack hose
and is available in w-inch and 1-inch
diameter and in 50-, 100-, and 150-foot
lengths. The lightweight construction
includes a woven fabric jacket, a plastic
helical reinforcement component, and a
coating to improve abrasion resistance. It
handles like a lay-flat hose yet performs
like a rigid reel hose and provides water
repellency, abrasion, oil and chemical
resistance.
