Kalrez parts give you a proven, cost-effective way to extend seal
service life. They have more than ten years of performance in
aggressive fluid environments involving harsh, corrosive or hazardous
materials, and a range of process temperatures to 600 degrees
F (316 degrees C).
combining the chemical resistance of Teflon fluorocarbon resin
with the sealing force of rubber, Kalrez seals can help improve
process productivity, reduce maintenance and downtime, and maintain
safety - anywhere premature seal failure or leakage can be a costly
seals have excellent thermal resistance; superior to all other
commercially available synthetic rubbers.
seals are rubbery, rather than stiff, unlike engineering plastics.
They are most easily fitted in place, and they conform better
to rough surfaces.
parts are resilient. They do not require spring loading, as do
some engineering plastics in certain sealing applications.
parts fit existing O-ring grooves, enabling immediate upgrading
of seal systems.
seals are versatile. In addition to a broad assortment of standard
size O-rings, they can be custom-made to specified shapes and
close tolerances. If required, special metal inserts can be incorporated.
parts are homogenous - not sheathed or coated with fluorocarbon
materials which can be subject to permeation, embrittlement, kinking,
stiffness or fretting of contact surfaces.
seals are non-rigid. They do not require the extreme compressive
sealing forces of metallic seals and are far more effective than
metals in dynamic sealing applications.
parts have good compression set and creep resistance characteristics.
Unlike packing materials, they do not need periodic tightening
to compensate for creep, nor do they require the extra space and
complexity of gland construction for such adjustments.
parts are serviceable over a broad range of pressures, compared
to other rubbers, plastics and packing materials.
parts have low outgassing characteristics and are available in
formulations that comply with FDA regulations.
