T-Seals
etc
Our unique machining facility enables
us to customize the seal size to fit
your equipment, plus minimum order
of just 1 piece. We offer seals from
5 mm to 2500 mm in diameter.
Details on the part numbers and sizes or custom
made seals not listed here are available on
request. |

Selection
of a Seal : -
The selection criteria are generally
the requirements, which have to be
met by a seal. It must
achieve the required degree of tightness.
Be made
from a material with adequate elasticity
and dimensional stability to compensate
for variations of
the cylinder inner diameter.
Be resistance
to extrusion, even a large gap at
high pressure. Must have
good compatibility with the media
throughout the working temperature
range. A low swell
is necessary. Must have
a good sliding feature (low friction),
high abrasion resistance and
be easy to install and
replace. The material
should not wear and allow particles
to enter the system. In
addition to these, there are other
operating conditions, which affect
our analysis.
Some of these are as follows : -
The system
pressure. The seal must be able to
operate at high pressures and
still be tight at low pressures.
The stress
imposed by the variations of the pressure
when working. The location
of the equipment, outdoor or indoor.
The working
temperature range. The installation
conditions. The length
of stroke and frequency.
The speed
of movement. The expected
friction, like stick slip behavior.
The operating
and stationary periods.
Type and
characteristic of seal materials.
The media
specification and compatibility with
the material
These conditions have an effect on
the performance of the seal service
life, leakage, friction, wear and
reliability. These are important and
influence the selection of the optimum
seal shape and material. |

| Installation
of a Seal : -
Another important
factor to consider in order to
obtain the best performance of
the seal is that the seal must
be installed correctly. The sealing
edge of the seal must be protected
from damage during installation
as they are the parts which perform
the sealing contact point. Remember,
seals are the parts that control
the efficient working of the equipment
and should be treated with care
during installation.
