Upon placement of the housing aroundthe Gasket and into the grooves, the Gasket is posi-tioned. As the housing segments are tightened, theresilient elastomeric Gasket conforms to the internalcavity of the housing and is further compressed, en-hancing the Gasket s seal against the pipe. The Victau-lic Gasket is pressure combination of these characteristics creates apermanent, leak-tight triple seal on a variety of pipingmaterials including carbon steel, stainless steel alumi-num, PVC, cast iron and pressure serves to strengthen the seal through thecombination of normal Gasket resilience, housing rein-forcement and the action of pressure downward on the Victaulic Gasket design seals equally well undervacuum.

2 Vacuum creates a pressure differential betweenthe inside and outside of the piping system. The resultingincreased force from external pressure differential hasthe same seal strengthening effect as internal ServiceThe Victaulic Gasket design seals equally well underpressure or vacuum. Vacuum creates a pressure differentialbetween the inside and outside of the piping system. Theresulting increased force from the external pressure has thesame seat enhancement effect as internal pressure. For con-tinuous vacuum service greater than ten inches of mercury,we recommend the use of molded Victaulic FlushSeal gaskets or Victaulic standard gaskets with a metal ring liner,both available from your Victaulic distributor. The FlushSealfeature and the metal liner both prevent distortion of thegasket due to the pulling action of a high vacuum at the centerof the Gasket .

Its primary focus is on contaminantsor impurities which may be imparted indirectly to drinkingwater. Materials that do not come in direct contact with thepotable water do not require classification categories for pipe and related prod-ucts and joining and sealing materials, as established byANSI/NSF 61 are cold , which is limited to +86 F (+30 C)maximum and hot which is limited to +180 F (+82 C)maximum.

4 These categories were established by the maxi-mum ambient distribution temperature of unheated waterfor cold and a temperature well in excess of a scaldingtemperature for hot domestic water. The following listrepresents the current classifications on our products:EPDM E gaskets :UL classified in accordance with ANSI/NSF 61 forcold +86 F (+30 C) and hot +180 F (+82 C) potablewater Butyl M gaskets :UL classified in accordance with ANSI/NSF 61 forcold +86 F (+30 C) potable water PPS Coating:The black PPS (Polyphenylene Sulfide blend) coat-ing applied to our Vic -300 butterfly valves is UL clas-sified in accordance with ANSI/NSF 61 for cold +86 F(+30 C) and hot +180 F (+82 C) potable water 304 and Pressfit Stainless(Type 316) Couplings and Fittings.
