When classic sealing materials – for instance in temperature ranges
above 300°C and below -50°C – reach their limits alternative
materials are required such as metal with appropriate
coating/plating....

Most pharmaceutical manufacturers produce drugs in large vats of
living cell cultures. For the production of these drugs, it is
extremely important to ensure that these cell cultures are not
exposed...

More often than not, an O-ring makes for a great sealing element.
They seal over a wide range of pressure, temperature and tolerance.
Normally they require very little room, are readily available,...

Are you uncertain of what to look for when comparing material data
reports for various elastomers? Ever wonder about the impact
a seal’s durometer has in the application? Have you asked, ‘What...

We've all done it at least once: looked at a report, read the
numbers on it, and come up with exactly the wrong conclusion.
Pass/fail limits and results are printed right there, but for some
reason,...

I have had many discussions with customers as to the value of using
an ASTM elastomer compound description on their prints to define a
specific application or elastomer requirement versus listing...

Seals made of the fluoropolymer PTFE are used where many other
sealing materials (such as rubber elastomers, polyurethanes,
fabric-reinforced elastomer seals, etc.) reach their limits in
terms of...

In our July Semiconductor entry, we noted that lowering the
cost of ownership is a multi-faceted goal. We discussed how one of
the areas for potential improvement is mechanical design and how
the...

Closure force requirements are an important consideration for
sealing applications, and the Applications Engineering team is
often asked for guidance as to how to minimize or predict the
amount of...

I had a brief career in construction. We used an old hydraulic
manlift for elevated projects, and it had a problem – we would
start the day eye-level with our work, and after an hour would
realize we...

You just spent 6 months testing, stretching, aging and exposing
your new seal design to 12 different chemicals. Finally, you are
done, so what does a good technical drawing for a seal include?...

Another Electric & Hybrid Vehicle Tech Expo North America has
concluded and it is evident that this show has grown by
leaps and bounds. In just a few years since Parker Hannifin has

For some applications, a critical component of selecting a seal
material is a phenomenon known as “outgassing”. However, even
within the elastomer community, outgassing is not something that...

As automatic transmissions become more advanced as a system, the
components within must evolve as well. Performance drives the
design and there are many factors that must mesh together to
achieve the...
