Gask-O-Seals
Gask-O-Seals have the elastomer molded directly within the groove or grooves of metal or plastic retainer. During assembly, the rubber seal is deformed a predetermined amount to very nearly fill the void areas to achieve controlled confinement, Gask-O-Seals are very reliable elastomer-bonded-to-metal or plastic sealing devices intended for applications requiring extreme reliability, longevity and durability. They are used in a wide range of military, communications, aircraft and marine applications.

Integral Seals Integral seals are custom engineered sealing devices designed to solve specific customer sealing problems. The integral seal design bonds the elastomer sealing element to thin metal or engineered plastic retainer plates, allowing for a very complex sealing geometry, ease of assembly and reliable service in a single seal element. These reliable seals are best suited to high-volume OEM or retrofit application in automotive, industrial, aerospace and military applications. Read More |

Metal Seals and Gaskets Valley Seal provides metal seals in a wide range of base metals and plating finishes. Applications include cryogenic, high vacuum, ultra-low leakage, high radiation, and significant thermally included movements. They are suitable for use in compressors, heat exchangers, jet engines and other high-temperature or chemically reactive applications. They are available as metal jacketed gaskets, corrugated gaskets in a wide range of sizes and shapes. Our resilient metal seals include O, C, E, U and V sections from 0.031” to 0.625” (0.78 to 15.8mm) with any diameter from 0.180” (4.6mm) upwards, depending on the selected product. We also manufacture AS1895 E type seals and MS9141 and 9142 metal O-rings. Read More |

PTFE back up rings PTFE back-up rings are designed to prevent extrusion in rubber O-ring sealing systems. Rubber O-rings generally serve as effective seals for dynamic and static applications in hydraulic and pneumatic systems equipment. One big drawback of rubber O-rings is their tendency to extrude into the clearance of mating surfaces when subjected to increasing pressures and temperatures. Elevated temperatures (160°F and higher) impose a severe burden on the physical and mechanical properties of rubber O-rings, which further increases their tendency to extrude. The combination high pressures and high temperatures is a common occurrence in present day fluid systems. Moreover, the trend is toward still higher pressures and longer resident times at elevated temperatures. This places more emphasis on the role of the back-up ring in preventing O-Ring extrusion.
