Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

3.6.3.6
reusable hose fitting
reusable coupling
hose fitting (3.6.4.1) that is so designed that it can be disassembled from a hose assembly (3.1.2) and
reassembled to another hose assembly without losing its function
3.6.3.7
built-in hose fitting
hose fitting (3.6.4.1) that is built into the hose construction during manufacture, and subsequently
vulcanized in position
3.6.4 Parts of hose fittings, couplings and other components
3.6.4.1
hose fitting
coupling
connector
end-fitting
fitting, usually made of metal, attached to the end of a hose (3.1.1) to facilitate connection to equipment
or another hose
Note 1 to entry: A female fitting carries the internal fastening; a male coupling carries the external fastening.
3.6.4.1.1
swivel coupling
coupling (3.6.4.1) that allows the fitting to rotate
3.6.4.1.2
elbow
hose fitting (3.6.4.1) bent to present the termination at a more suitable connecting angle
Note 1 to entry: Standard angles of 90°, 60°, 45° and 30° are common, with customized variations.
3.6.4.2
clamp
hose clamp
metal band around the outside of a hose to bind the hose (3.1.1) to a hose fitting (3.6.4.1), thus making a
hose assembly (3.1.2)
3.6.4.2.1
interlocking clamp
clamp that engages the hose fitting (3.6.4.1) in a manner which prevents the clamp from sliding off the
hose fitting
Note 1 to entry: Note1 to entry: Typically, a bolt or U-bolt with fingers which interlock with a ring on the fitting.
3.6.4.2.2
band
thin strip of metal used as a non-bolted clamp
3.6.4.3
bead
raised ring on the end of a nipple (3.6.4.10), typically of a semi-circular profile which is machined, cast,
or roll-formed and used to prevent the hose fitting from slipping out of the hose or a metal ring that is
welded, shrunk or cast on to the outer surface of a nipple
3.6.4.4
barb
one or multiple raised rings on the nipple (3.6.4.10), typically of a ramp-shaped profile which is
machined or cast
