Ferrules
Valco metal ferrules cut a ring near
the end of the tube, preventing tube
release at high pressures without
significantly deforming and restricting
the tube interior. (However, if the
hardness of the tubing is equal to
or greater than that of the ferrule,
deformation of the tube rather than
a cut ring is likely.) Make up usually
takes only about a 1/4 turn beyond
the point where the ferrule first starts
to grab the tubing. Polymeric ferrules
seal by the increased friction from
compression.

– Not available
Larger sizes and/or specific materials may be available on special order.
Valco zero volume ferrules may be
used with all Valco fittings and with
those of most other manufacturers.
The maximum pressure limit is
generally determined by the yield
strength of the tubing. The maximum
pressure for softer materials (such
as brass and polymers) is lower, and
depends on the tubing used. If in
doubt about a particular combination,
consult our technical staff.
For trace gas analysis, use gold-plated
ferrules to achieve sealing with
