Plain End
All hose construction elements (including wire, if wire is used as a reinforcing member)
are exposed. The hose always has the same inside diameter throughout. In the case
of certain hand-built specifications having wire reinforcement, the wire and fabric
reinforce­ment are not exposed.
All vertical spiral hose is available
only with plain ends.
Horizontal spiral and wrapped ply
machine-built hose is furnished with
plain ends unless otherwise specified
in the pricebook.
Built-In Nipple End
The hose end is integrally built around and bonded to the nipple body. The hose
reinforcing materials are also anchored to the nipple.
The nipples used are generally fabricated from pipe. Nipples made from standard
pipe will be full bore only when pipe
12” and under is used since nominal
pipe sizes over 12” are described by
pipe OD and not ID.
Available only in hand-built hose
constructions.
Swaged End
Primarily used on petroleum OS&D dock hose as an alternative to built-in nipples.
The steel (carbon or stainless) stem/
coupling accommodates threaded,
slip-on or welded flanged ends.
Stem/coupling attached to hose with
swaged steel ferrule over the cover.
Enlarged End
The hose end is enlarged to accommodate the outside diameter of the shank of a fitting
plus the depth of the shank. The helical wire is terminated at the enlarged end.
The inside diameter of a “standard” enlarged end is the same dimension as the outside
diameter of the same nominal pipe
size. (Example–6” ID hose enlarged
to 65/8” at the end, handles a 6” size
pipe which has a 65/8” OD.)
Normally used in hand-built hose
constructions.
