March 2008 Problem Solved - Compression Set
Compression Set - O-Ring Failure
Compression set is a term referring to the flattening or loss of the original, circular shape
on all contact surfaces of an elastomeric seal. As one of the most common causes of o-ring failure, compression set can be attributed to various conditions, such as excessive squeeze, incompatible fluid, improper gland design and gland overfill. However, the most common cause is a low quality elastomer with poor set resistance. _______________________________________________________________________________

Parker’s Parofluor ULTRA consists of high performance perfluorinated elastomers and
was developed for use in harsh operating environments. Compound FF500-75 is a black,
75 durometer material offering outstanding performance in the widest possible range of chemical and steam temperatures up to 275°C (525°F). It is suitable for use in acids, bases, amines, steam, ethylene oxide, and many other aggressive chemicals. _____________________________________________________________________________
January2008 Spiral Failure
Identifying Spiral Failure - What is it?
Spiral failure is defined as a type of O-ring failure caused when a seal becomes “hung-up”
at one point on its diameter, sliding and rolling at the same time. It twists as the seal device cycles, causing the ring to develop a series of deep spiral cuts on the surface. This type of
failure is often found on long stroke hydraulic piston seals and rod seals.

November2007 Bulletin12 Engineered Solutions
Application: Product development activities where elastomeric components are used.
Problem: Traditional product development involves prototyping multiple designs to find an adequate solution. In simple cases or where nearly identical solutions have been developed
in the past, only one or two prototype iterations may be needed. However, when developing
new or substantially enhanced products, time-to-market and development costs can be drastically increased by the need for many prototype cycles and experimentation.

September2007 E0740 Problem Solved!
Nuclear Technology Radiation Resistance
One of the most critical properties of an o-ring being exposed to radiation is its compression set. When a seal is exposed to gamma radiation, compression set is the most severly affected. Elastomers which are compounded for exposure to radiation must also pass stringent quality and material tests. Additionally, the elastomer must be compatible with the contact medium under the working environment (temperature, pressure, etc.).

August2007 Outsourced O-Ring Materials
A Closer Look Outsourced O-Ring Materials
Quality and cost are two key factors that drive customer satisfaction. Consumers demand low prices while manufacturers strive for quality. With rising raw material costs, this combination of quality and affordability has driven global product to the forefront. Numerous industries take advantage of outsourced product to keep profit high and costs low. However, massive recalls on China made products are raising concerns on how reliable outsourced product truly is.

June2007 Parkerslick Problem Solved!
Parker Parofluor ULTRA™ FF200-75 Exceeds AMS 7257C Requirements
Aerospace specification AMS 7257C provides the minimum requirements a material must
meet to be considered capable of long term exposure up to 550°F and exposure to petroleum
oils, jet fuel and phosphate ester hydraulic fluids.. Aerospace applications subject to this
specification have extremely high temperatures and are exposed to various environments.
Because many applications demand excellent seal performance in extreme environments, customers may choose to specify a material that exceeds the AMS 7257C standard.

June2007 Bulletin11 Engineered Solutions
Application: Parker ESD has developed a reinforced seal for an axial seal joint where an inside support wall is not practical.
Problem: An axial seal was required to seal water between three concentric components in a newly developed shower head. Packaging constraints dictated a very narrow sealing area with no support on the inside face of the seal. Traditional seal designs were extruding out of the seal gap into the water stream and failing.

May2007 Bulletin10 Engineered Solutions
Engineered Solutions - Parker Engineered Seals Division
Summary: Parker ESD has developed a family of fluorocarbon compounds with excellent resistance to fluids which degrade traditional fluorocarbon elastomers.
Problem: Applications exist where multiple fluids contact a single seal, while other applications use similar seals in various fluids. Having a single, compatible seal material is highly desirable in these applications for design flexibility and to prevent premature seal failures. _____________________________________________________________________________

March2007 Bulletin9 Engineered Solutions
Engineered Solutions - Parker Engineered Seals Division
Application: Automatic transmission hydraulic circuits with multiple separate high pressure fluid circuits grouped in close proximity. “Cluster”
Problem : Automatic transmissions often have multiple high pressure fluid circuits that require sealing. This previously required purchasing, stocking, & installing several different seals of various sizes.

March2007 Bulletin8 Engineered Solutions
Engineered Solutions - Parker Engineered Seals Division
Application: Tube seals for fluid & gas applications under positive or negative pressure (Pressure or Vacuum).
Problem: Sealing of joints between tubes & bore housings historically has been accomplished by using conventional compression seals. The previous seal option has only one seal contact point which is not self energizing & is entirely dependant on rubber compression.

March2007 Bulletin7-II Engineered Solutions Engineered Solutions - Parker Engineered Seals Division
Application: Automatic transmission high pressure hydraulic circuits.
Problem : Recently developed automatic transmissions have high pressure fluid transfer sealing requirements that must bridge a gap

March2007 Bulletin7 Engineered Solutions
Engineered Solutions - Parker Engineered Seals Division
Application: Fuel Tank Seal
Problem: Many fuel tanks have minimal overlap between the sending unit and fuel tank flanges. As a result, misalignment between components or out-of-round flanges create a need for an offset between seal beads that contact the two components. Traditional seals cannot generate seal pressure with offset beads since rubber twists easily. In addition, installation of the sending unit can twist the seal causing critical damage. In extreme cases, the seal may be twisted out of position and into the fuel tank.
