Face Seal Fittings

GENTEC specializes in designing and manufacturing of high quality valves and fittings for High Purity and Ultra-High Purity applications. GENTEC FSR fittings, made from 316/316L/316 VAR, are supplied in BA or EP grade, cleaned, bagged individually in clean room nylon bags, and heat-sealed. The inner bag is then placed in a polyethylene outer bag and heat-sealed in a class 100 clean room to meet the severe demand of the semi-conductor industries.PlatingThe FSR female nuts are silver-plated. Avoid chemical processes used for cleaning, electropolishing and passivation that will remove plating. If the plating is damaged or removed, thread galling will occur, damaging fitting components and preventing a proper seal.Dimensions* Dimensions are in inches for reference only without notic and subject to change.Pressure RatingsRatings are based upon tests conducted using FSR assemblies
All ratings comply with calculations per ANSI Code for Pressure Piping B31.3
Working pressure ratings determined at room temperature. Allowable working pressure of elevated temperatures could be obtained by multiplying factors shown in the following table.
TestingThe FSR assembly has been helium-leak tested to a rate of 1 x 10-9 std cc/sec without leakage.Ultra-High-PurityA variety of FSR face seal glandes and bodies are available with controlled surface finishes, electropolished, and specially cleaned to meet Ultra-High-Purity system requirements.Heat code traceabilityMaterial heat code is stamped on glands and all shapes to ensure raw meterial traceability.
