Durlon® CFG

Durlon CFG corrugated 316 stainless steel metal core with flexible graphite sealing surface will maintain a tight seal in a wide range of initial seating stresses making it the universal replacement for spiral wound, double jacketed and traditional flexible graphite gaskets. It is suitable for virtually all applications found in the following industries: refining, chemical, petrochemical, pulp & paper, power generation and steel mill.

Durlon® Durtec

Durlon® Durtec™ gaskets are made with a specially engineered corrugated metal core that is bonded on both sides with soft covering layers, typically fexible graphite. The core is produced by patented technology that allows the finished gasket to have the best possible mechanical support function. Corrugations in the Durtec™ core are virtually uncrushable unlike conventional corrugated metal core gaskets. The precision construction guarantees that Durlon® Durtec™ gaskets will have excellent sealing characteristics even under low bolt loads.

The Durtec™ Advantage

• Fire Safe- SS316L/Graphite Passed Modified API 607 fire test
• Blow Out Resistant- Metal core provides excellent resistant to internal pressure spikes
• Reusable - On larger sizes and for special configurations, the core may be refaced with new material and reused provinding lower cost of ownership
• Superior Core Technology- Durtec™ design can allow for complete replacement of spiral wound and Kammprofile gaskets with improved performance and lower life cycle cost
• Easy and safe to hanfle, easy to install
• Seals tightly with lower bolt loads vs. spiral wounds and Kammprofiles

Durlon® Flexible Graphite FGL316

Standard industrial grade sheet laminated with an adhesive bond on both sides of a .002" thick 316 stainless steel foil insert. Used where high performance and handleability is important.

Durlon® Flexible Graphite FGS95

Standard industrial grade sheet containing no binders or resins. Used in industrial applications such as oil refineries, power plants and chemical process plants.

Durlon® Flexible Graphite FGT316

Standard industrial grade sheet mechanically bonded on both sides of a .004" thick 316 stainless steel metal tang core. Used where stresses and pressures are high and improved handleability is important.

Durlon® Kammprofile-K40P & K40C

This basic configuration is most often used in tongue/groove and male/female flanges.

Durlon® Kammprofile gaskets are the preferred choice for applications requiring improved performance at low seating stresses. The serrated peaks provide reduced contact area and when combined with the soft conformable sealing layers, the Durlon® Kammprofile gasket provides a virtual metal-to-metal connection. They feature excellent resistance to blowout and provide superior stability for ease of handling and installation.

Durlon® Kammprofile-K40PEF and K40CEF

Similar to the floating centering ring, this style has an extended core whereby providing additional strength and stability to the overall floating design.

Durlon® Kammprofile gaskets are the preferred choice for applications requiring improved performance at low seating stresses. The serrated peaks provide reduced contact area and when combined with the soft conformable sealing layers, the Durlon® Kammprofile gasket provides a virtual metal-to-metal connection. They feature excellent resistance to blowout and provide superior stability for ease of handling and installation.

Durlon® Kammprofile-K40PF and K40CF

A loose fitting centering ring is recommended on applications where thermal or pressure cycling can affect the integrity of the serrated metal core. It allows for expansion and contraction of the core through these cycling conditions.

Durlon® Kammprofile gaskets are the preferred choice for applications requiring improved performance at low seating stresses. The serrated peaks provide reduced contact area and when combined with the soft conformable sealing layers, the Durlon® Kammprofile gasket provides a virtual metal-to-metal connection. They feature excellent resistance to blowout and provide superior stability for ease of handling and installation.

Durlon® Kammprofile-K40PI and K40CI

The centering ring is used to position the gasket between flat face and raised face type flanges.

They feature excellent resistance to blowout and provide superior stability for ease of handling and installation.

Durlon® RTJ - Style BX

Durlon® Style BX gaskets have a pitch diameter slightly larger than the groove pitch diameter. This allows for initial contact to be made on the outside of the ring, pre-loading the gasket which creates a pressure energized seal.

All Durlon® Style BX gaskets incorporate a pressure passage to enable trapped pressure to balance itself in the joint.

Style BX ring joint gaskets can only be used with API BX flanges and are not interchangeable with style RX.

Durlon® RTJ - Style R

Available in oval and octagonal cross-sections.

Durlon®Style R gaskets are interchangeable on modern octagonal flat bottom grooved flanges.

Standard sizes of Style R gaskets are manufactured in accordance with ASME B16.20 and API6A specifications.

Durlon® RTJ - Style RX

The Durlon®Style RX ring joint has a unique self-sealing action. The outside levels of the ring make the initial contact providing a seal against the grooves outer surfaces. As the internal pressure increases, so does the gasket loading stress against the groove thus improving the gaskets sealing characteristics.

Design features of the Style RX gasket make it more resistant to shock load, test pressure shock, and drilling vibration.

Style RX ring joints are completely interchangeable with standard Style R groove designs. Care should be taken when interchanging these styles as Style RX gaskets are taller and will add length to the finished assembly.

Durlon® SELEX Zero Leakage Gasket

Durlon^® Selex zero leakage gaskets are composed of stainless steel inner and outer rings with highly compressed pure nuclear grade flexible graphite sealing elements using a proprietary compression molding process. Selex gaskets exhibit superior mechanical intensity, compressibility and recovery, stress relaxation, and low bolt loading requirements while still providing “ZERO” leakage [≤1x10^-7 Pa·m³/s (He)].

• Style DRI- Sealing element (D) centering ring (R) and inner ring (I) which protects the sealing element from erosion, inward buckling and improves radial strength.

Durlon® SWG- Style D

Style D- Sealing element.

Durlon® Spiral Wound Gaskets (SWG )are made with an alternating combination of a preformed engineered metal strip and a more compressible filler material which creates an excellent seal when compressed. The engineered shape of the metal strip acts as a spring load,resulting in a very resilient seal under varying conditions.

The strip metallurgy and filler material can be selected to seal a wide range of applications. All Durlon® styles have been engineered to precise manufacturing tolerances that allow for lower stress (bolt load) sealing compared to conventional spiral wound gaskets.

All Durlon® SWG's are manufactured according to ASME B16.20 standards. Quality Assurance complies with API Specification Q1 and ISO 9001:2000.
