Type "E" Gaskets
Type "E" Gaskets extend to the outside diameter of the flange. They feature precision located bolt holes, to automatically center the gasket, and offer maximum protection against foreign material "shorting-out" the flange.
Type "E" gaskets may be ordered in any one of the following configurations:
LineBacker® Sealing Gaskets
GasketSeal® Sealing Gaskets
Neoprene Faced Phenolic Gaskets
Plain Phenolic Gaskets
Red Devil Gaskets
Yellow Jacket Gaskets
Garlock Gaskets
Teflon® Gaskets
When configured as a LineBacker® sealing gasket, the sealing element may be positioned anywhere between the I.D. of the gasket and I.D. of the bolt circle.
Type "F" Gaskets
Type "F" Gaskets are made to fit within the bolt hole circle of the flange. The O.D. of the gasket extends out to the I.D. of the bolt hole circle for good protection against foreign material "shorting-out" the flange. When configured as a LineBacker® sealing gasket, the sealing element may be positioned anywhere between the I.D. and O.D. of the gasket. Type "F" gaskets may be ordered in any one of the following configurations:
LineBacker® Sealing Gaskets
GasketSeal® Sealing Gaskets
Neoprene Faced Phenolic Gaskets
Plain Phenolic Gaskets
Red Devil Gaskets
Yellow Jacket Gaskets
Garlock Gaskets
Teflon® Gaskets
When configured as a LineBacker® sealing gasket, the sealing element may be positioned anywhere between the I.D. of the gasket and I.D. of the bolt circle.
Type "D" Gaskets
Type "D" Gaskets are available for RTJ flanges but the LineBacker® sealing gasket is an excellent alternative to "D" gaskets because the sealing element may be positioned anywhere between the I.D. of the gasket and I.D. of the ring groove.
PSI Isolating Gaskets - Standard 1/8" Thick
 GasketSeal®
GasketSeal sealing gaskets are considered one of the most effective methods for sealing and isolating flanges of all types. The gasket consists of two molded semi "O" rings (with precise crown-to-void ratio) mounted in grooves on opposite sides of an isolating retainer. While maintaining all the advantages of a full "O" ring seal, the semi "O" ring seal eliminates the need for a sealing groove in the flange face to reduce problems associated with alignment. GasketSeal sealing gaskets incorporate near zero "m" and "y" factors that make it possible to effect a positive seal without tremendous bolt loads required with flat gaskets. GasketSeal sealing gaskets are available in a wide variety of retainer and sealing element combinations for matching gaskets to service and environmental conditions. Refer to the chart for the GasketSeal sealing gasket temperature ranges and material compatibilities. More information: PSI GasketSeal Sealing Gaskets
LineBacker®
LineBacker sealing gaskets utilize a patented rectangular sealing element, referred to as a "quad" ring, in combination with a unique groove design to effectively seal and isolate flanges of all types. With the unique "quad" ring design, elastic memory is provided for elastomers not normally associated with this characteristic. Materials such as polyimide, TFE (Teflon) and vinyl may therefore be used as sealing elements. which dramatically increases the options available for matching gasket materials to service and environmental conditions. This greater variety of materials also provides excellent temperature and chemical range compatibility. LineBacker sealing gaskets incorporate near zero "m" and 'y" factors that make it possible to effect a positive seal without tremendous bolt loads that are required with flat gaskets. Refer to the chart for LineBacker sealing gasket temperature range and material compatibilities. More information: PSI PSI LineBacker Flange Sealing Gaskets and PSI LineBacker™ Zero, 250 & 251 Sealing Gaskets
Neoprene Faced Phenolic
Neoprene Faced Phenolic gaskets have been used as standard "flat" isolating gaskets in the oil and gas industries for many years. Soft neoprene rubber sheets are factory applied to both sides of a laminated phenolic retainer providing an effective sealing surface. The temperature limit of these gaskets is approximately +175° F (80°C). Note: Due to improved sealing characteristics and retainer / seal element options, LineBacker or GasketSeal sealing gaskets should be considered in lieu of neoprene faced phenolic gaskets whenever possible.
Flat Gaskets
Flat Gaskets are used in special applications such as elevated temperatures that often require materials such as Red Devil or Yellow Jacket. Please contact Corrosion Control Products Company for additional information on available options.

These are organic materials that will feed a fire if a leak occurs and an ignition source exists.
Ammonia (wet) - Data to +100°F (+38°C) only (same materials as dry).
For pipe diameters over 24" or ANSI Class pressure ratings of 600# or greater, use G-10 sleeves and G-10 washers where temperatures and other conditions permit.
