Contamination With Seals
Neglecting routine maintenance can cost you in seal performance or, in some cases, end with catastrophic failure. Prolonged downtime will incur losses that exceed the temporary cost of preventative maintenance.
It’s important to identify seal contaminants and their sources before they turn into larger issues. Here are some tips on what to look for and how to deal with them.
Common contaminants
Here are some typical contaminants you’ll come across:

UHMW Seals - Could They Be Right For You?
Ultra-High Molecular Weight Polyethylene, or UHMW, is an inexpensive easy to acquire seal material which, in the right environment, provides an excellent seal.
There are a set of operating criteria which designers should follow to take advantage of the many benefits that other materials like PTFE can’t offer.
In this article, we’ll explore the uses of UHMW, how and where to apply it, and the pitfalls to avoid.

High-Pressure, High Eccentricity Seal Solution Demonstrates 50% Improvement
On pressure and side-load performance of a fluid application
Recently, a customer was having difficulty with a seal failure on a fluid power application. The high-pressure, high-eccentricity seal operates in conditions up to 200,000 pv at 3000 psi and could not exceed maximum shaft deflection of 0.005″.
Unitized seals for input and output pinions in gear boxes, axle wheel ends, and trunnion

Tech Bulletin: How to Read an ASTM D2000 Standard Callout
Here at Gallagher, our engineering team loves to help customers with their technical and application challenges.
If you are new to the sealing industry, returning after a hiatus, or just haven't needed to be in-the-know with ASTM D2000, it can be a confusing concept. That's why we put together this handy 2-page tech bulletin to give you everything you need to know about how to interpret your own ASTM D2000 callout.

A common question that comes from many customers is: “Can you tell me which O-ring compound meets this ASTM D2000 callout?” It’s understandable, since at first glance, the ASTM D2000 callout can be intimidating for determining the type of O-ring material. However, the ASTM D2000 is a very useful tool to quickly specify requirements for O-ring materials, and is standardized so it is easy to interpret industry wide. So, what is the

VICTREX CT™ 200
VICTREX CT™ 200 is a High-performance thermoplastic PEEK polymer suitable for dynamic sealing applications at very low temperatures.
As the latest member of the VICTREX CT™ PEEK polymers, the 200 grade series exhibits improved sealing over a wider range of temperatures, compared to commonly used materials such as PCTFE. It does so at low temperatures on account of its greater ductility, and at high temperatures due to its superior creep resistance. It

More often than not, the process of parts material selection and/or development can get fairly involved. To summarize: it’s similar to a game of pros vs cons where so many different variables come into play. In the case of TPE, the principle is no different. Factors such as meeting the performance requirements for a specific application, economic assessments, and processing issues, should all be reviewed in order to make the optimal choice. Looking at the qualities and considerations

Natural Rubber Short Supply
Plagued by global supply chain issues stemming from coronavirus and environmental issues, the natural rubber shortage continues to be exasperated by the war in Ukraine and Russia.
In 2021, shortages were reported mainly due to flooding and leaf disease. A poor crop led to a decrease in the cultivation of these highly desirable trees. The supply for raw gum already was expected to remain tight for several years due to the 7-year maturity period
