General Information
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.
