Appendix D How
to Install Hose Connections As
illustrated in Chapter 5, and below, four different combinations of parts are
in general use for making up hose connections:
A – ”Screw-type” nipple
with heavy brass ferrule B
– ”Push-type” nipple with crimped ferrule
C – ”Push-type” nipple
with ”Sherman-type” hose clamp D
– ”Push-type” nipple with ”Circle-type” hose clamp
Virtually all packaged hose assemblies
are fitted with push-type nipples and crimped ferrules (B). To make up
connections of this type in the field
without special equipment is impossible. The combination of screw-type nipple
and brass ferrule (A) makes a strong,
very neat connection, but it is essential that the ferrule be sized to fit snugly
over the hose before the nipple is
installed. For most field purposes, the combination of push-type nipple and
circle-type clamp (D) is recommended.
Circle-type clamps cost less than Sherman-type clamps and aren’t subject
to possible loosening in service.
