TYPE 1
: Vertical Braided Hose
Entire hose length cured in one operation.
A. Extruded seamless tube.
B. Seamless reinforcing braids of synthetic textile wire, or other
material – applied by high speed vertical or horizontal braiders.
C. Rubber layers between braids establish positive bond between
braids when vulcanized.
D. Extruded, seamless cover.

applied so that each ply is laid at a given angle for maximum
dimensional stability.

BASIC HOSE CONSTRUCTION
GENERAL INFORMATION
The Four Basic Methods Of Hose Construction
Although we make more than 2,000 types of hose for specialized applications, there are only four basic construction methods
used. Since each of these four methods embodies certain fundamental characteristics that make it particularly suitable for
certain functions, an understanding of these methods may assist you in making the best use of this catalog. Keep in mind that
a reference to any one of these types of construction will imply all the characteristics and benefits outlined here plus specific
features attained through the proper compounding of rubber, choice materials, and variation in plies and thickness to ensure
that each hose is exactly right for the job for which it is designed.
COVER
The cover is the outermost or
visible area of the hose. It is designed
to be a protective covering against
wear, abrasion, cuts, weather, and the
general destructive action encountered
in normal service.
BODY or CARCASS
The body
reinforcement is the supporting
structure of the hose. It can range
from simple to complex combinations
and consists of cord, yarn, fabric, wire,
or any combination of these.
Tube or Lining
The tube is the
inner-most element of a hose and is
compounded to provide resistance to the
material being carried. With the wide
range of rubber compounds available, a
hose can be built to withstand abrasive
materials, chemicals, oil and a wide
variety of other materials.
