Reduce Exhaust Leakage in Heavy Duty Engines by 80 Percent with an Air Duct Seal
Increased emission restrictions are requiring engine manufacturers to conform to Euro 6 and Tier IV regulations to reduce exhaust leakage 80% or more. In order to achieve these new standards, engines with extreme temperatures coupled with a high amount of vibrational movement, need to have highly engineered sealing solutions. Applications with predetermined mating components cannot always be changed, so the need for a sealing solution with a similar coefficient of thermal expansion is needed.

But sometimes their dilemmas can be solved with more robust solutions instead of direct replacements. For example, when a customer is having issues with a PSA-backed hollow seal that keeps peeling away from the bottom surface.

Compression Set Failure Mode in O-Rings
Probably the most common cause of O-ring failure is compression set. An effective O-ring seal requires a continuous “seal line” between the sealed surfaces. The establishment of this “seal line” is a function of gland design and seal cross section which determines the correct amount of squeeze (compression) on the O-ring to maintain seal integrity without excessive deformation of the seal element.
Factors contributing to compression set failure of an O-ring seal:
1. Selection of material with inherently poor compression set properties.
2. Improper gland design.
3. Excessive temperature developed causing the O-ring to harden and lose its elastic - March 21, 2024

Double Chamfer Radial Seals
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, and easily sourced. However, there are specific applications that may be better suited for an alternate type of seal, such as a double chamfer radial seal.

Tadpole Tape - Is it Right For Your Application?
Tadpole Tape Seals under light pressure while resisting flame and prolonged high temperatures
Tadpole tapes are resilient and nonabsorbent, flame-resistant gasketing materials. They are especially suited for applications requiring sealing under light pressure where bolting force is limited, such as doors, aircraft mounting rings, turbine flanges and combustion chamber inlets.

An O-ring seal is a circular cross-section ring molded from rubber, used to prevent the loss of a fluid or gas in a gland. It is the most basic, and at the same time to the most widely used type of seal available since its invention in 1936 by Niels Christensen.

If the system does not pressurize properly, the entire piece of equipment should be disassembled and seals must be replaced. Depending on when this test occurs, multiple manufacturing steps could be in between the seal installation and the first step where leakage can be identified. If O-ring damage happens with high frequency, you could be wasting time and money

Download the Parker O-Ring Handbook
For more than 65 years, the Parker O-Ring Handbook has been an engineering staple of the sealing industry.
.... and now you can download it for free.
In 2015, Parker Hannifin Corporation launched an interactive digital reference guide to enhance and broaden the customer reach of the existing Parker O-Ring Handbook, the Parker O-Ring eHandbook.
“I’m constantly amazed and honored at how often I run across it in unexpected places,” says Dan Ewing, senior chemical engineer and materials manager at Parker's O-Ring division, “I've come to expect to see a well-used copy sitting on a customer's desk, but I'm pleasantly surprised when I find it cited in academic papers, referenced in reports written by government agencies and discussed in industry association meetings.”

Do you have an application where traceability and security is crucial for your sealing needs?
RFID for O-Rings
O-ring RFID (Radio Frequency Identification) is a technology that continues to improve by leaps and bounds. O-ring Identification is necessary in industries and applications where authenticity, traceability, and security are crucial.
