Ferrules
Valcometal ferrulescuta ringnear
theendof the tube,preventing tube
releaseathighpressureswithout
significantlydeformingand restricting
the tube interior. (However, if the
hardnessof the tubing isequal to
orgreater than thatof the ferrule,
deformationof the tube rather than
acut ring is likely.) Makeupusually
takesonlyabout a1/4 turnbeyond
thepointwhere the ferrulefirst starts
tograb the tubing. Polymeric ferrules
seal by the increased friction from
compression.

Themaximumpressure limit is
generallydeterminedby theyield
strengthof the tubing. Themaximum
pressure for softermaterials (such
asbrassandpolymers) is lower,and
dependson the tubingused. If in
doubt about aparticular combination,
