Isolation Gasket Solutions from Thermoseal

KLINGERSIL® C-7400 Isolation Gaskets

Application Overview:

Some applications in plants call out for isolation kits to maintain the integrity and reliability of a pipeline and piping system. Isolation kits are designed to work in conjunction with flanges, gaskets, and/or bolt sleeves and washers by eliminating metal-to-metal contact and halting static electric currents. At times they are relied upon for critical applications in severe temperatures and conditions.

KLINGERSIL C-7400 - Isolation Gaskets replace Isolation Kits

The Problem: 

Industry’s first choice are phenolic gaskets. They are often supplied in kits, but they are hard and typically take a lot of load to seal. And lack of load is the number one reason for gasket failure.

VIDEO: How to Lubricate an O-Ring

Lubrication of O-rings is extremely important. The greatest benefit of using a lubricant is typically obtained during installation.

Parker O-Lube - Lubricant for O-RingsUsing a lubricant is going to decrease the surface friction of the O-ring helping to prevent abrasion, pinching or cutting of the O-ring during installation.  Lubricating an O-ring can also help to seat the O-ring properly into the application, as well as aid and speed up automated assembly processes.

The proper method of applying a lubricant to an O-ring always seems to be an area of concern for many of our customers and there are many methods used in the marketplace. One is to apply the lubricant to the O-ring using your fingers, your hand or a brush. Another is to dip the O-ring into a container of the lubricant. A third method commonly used is to dispense the O-ring lubricant into the seal packaging and use what we call the “shake and bake” method.

The common goal of all of these different lubrication methods is to have a thin uniform film applied to the entire surface of the O-ring when completed. This will ease installation and provide best friction reduction.


Gallagher Fluid Seals is a Parker Authorized Distributor, with thousands of o-rings stocked at all times.  If you have any questions about o-rings, material compatibility, failure modes, etc, please don’t hesitate to contact us.

Semiconductor Manufacturing – Wet Process

Semiconductor Manufacturing - Wet ProcessesNEW White Paper Available!

Gallagher Fluid Seals recently added a new white paper to its Resources Page, Perfluoroelastomers for the Semiconductor Industry, written by Russ Schnell.  Below is an excerpt from the new white paper discussing plasma process manufacturing.  You can download the white paper in its entirety by clicking on the thumbnail to the right.


Semiconductor Manufacturing - Wet ProcessesAlthough this is a smaller segment of the semiconductor chip manufacturing industry, it still plays an important role. Wet processes can be used in cleaning, etching, and other steps in chip manufacture. Wafers may be cleaned and rinsed after initial wafer preparation. This step removes residual particles and other contamination on the wafer surface. The wafer may then be exposed to chemicals for adhesion promotion and/or photoresist deposition. After photoresist is applied to the wafer surface, the wafer can be exposed to a number of photolithography steps. The wafer may then be exposed to liquid developer solutions and photoresist stripping solutions. Resist strippers usually involve aggressive acids or organic solvents. Finally, wet processes can also be used in etching processes, which typically involve strong acids.

85 Years of the Simmerring®

Small, nondescript and ostensibly unspectacular – it is often developments of this exact description that lead to groundbreaking innovations in the world of technology. The idea of manufacturing seal sleeves from leather scraps became the starting point in one of the most important developments in sealing technology: the Simmerring®. For 85 years, the Simmerring has been inseparable from the Freudenberg history of success, and, in Europe, its name has even become a synonym for (radial) shaft seal rings of every kind. Today the Simmerring is a high-tech product whose key functions go far beyond the sealing of the shaft against its housing.

Freudenberg SimmerringIt all started with the economic crisis of 1929, which plunged the leather industry and thus the Freudenberg tannery – which was founded in 1849 – into difficulties. To better distribute its risks in the future, Freudenberg began to diversify the company and serve a broader market. A sample of a leather sleeve from the United States was the inspiration for giving Walther Simmer and his team the job of developing a machine that could be used to produce lip seals made of leather scraps.

Protect Your Seal Aftermarket with Part Identification Technologies

Protect Your Seal Aftermarket with Part Identification TechnologiesParker is revolutionizing part identification technology with a multitude of options. Customers are able to benefit from various identification methods such as non-permanent and permanent part markings by selecting their part number and company logo on the seal. For more advanced identification, a customer may opt to use the Parker Tracking System or utilize our RFID seals for tracking purposes. These identification methods ensure product authenticity and reduce seal installation errors by providing visual indicators for the assembly process.

Basic part marking – non-permanent identification

Non-permanent markings are applied to the surface of the seal and can be in the form of a company logo, unique part number, barcode, or other seal information. Non-permanent markings ensure Parker’s part origin, enables part level traceability and provides an easily visible cue to operators. This value-added feature helps reduce installation errors in addition to protecting customers against counterfeit seals.

Ring-Type vs. Full-Face Gaskets

When sealing raised or flat face flanges, there are two choices of gasket shape: ring-type or full-face.  Each has its own advantages, so you should know which will best suit your application before ordering and installing. First, let’s discuss the types of flanges in which gaskets are installed.

Flange Faces

Different types of flange faces are used as the contact surface to seat the sealing gasket materials.  ASME B16.5 and B16.47 define various types of flange facings, including the raised face, the large male and female facings which have identical dimensions to provide a relatively large contact area.

Raised Face (RF) Flanges

Raised Face FlangesThe Raised Face flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face. This face type allows the use of a wide combination of gasket designs, including flat ring sheet types and metallic composites such as spiral wound and double jacketed types.

The purpose of a RF flange is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint. Diameter and height are in ASME B16.5 defined, by pressure class and diameter. Pressure rating of the flange determines the height of the raised face.
