FLEXSEAL ®RW, RWI and SW GasketsAdvantages■■■■■Style RW■■■General purpose gasket suitable for flat face andraised face flanges up to Class 2500Centering ring accurately locates the gasket onthe flange face, provides additional radialstrength, and acts as a compression limiterSpiral winding (sealing element) consists ofpreformed metal and soft filler materialNOTE: An inner ring is recommended for applications aboveClass 600, due to the high available bolt load. See Style RWI.Style RWI■■■Suitable for flat face and raised face flanges up toClass 2500Recommended for higher pressure applications,for use with PTFE fillers, and when delineated byASME B16.20Inner ring acts as compression limiter and protectssealing elements from process media attackStyle SW■■■Durable; easy installation and removalSeals pressures to flange ratings, in accordancewith ASME B16.5Suited to temperatures from cryogenic to2000°F (1093°C)Guide ring simplifies centering of sealingelement on the flange faceCustom-tailored solutions accommodate avariety of conditions by combining variousmetals and filler materialsSuitable for tongue and groove, male-female, orgroove-to-flat face flangesSpiral winding only, containing preformed metaland soft filler materialInner and outer diameters of winding are reinforcedwith several plies of metal without filler togive greater stabilityNOTE: Also available with inner rings—Style SWI.Ordering InformationRW / RWIWhen ordering specify:■ Nominal pipe size and pressure rating■ Winding and filler materials■ Centering and/or inner compression ring materialSWWhen ordering, specify:■ O.D. and I.D. dimensions (and tolerance, if otherthan standard—see page 13)■ Thickness of gasket■ Winding and filler material■ Inner ring material, if required (Style SWI)■ Pressure ratingNote: For M & Y factors, see page 27.For ROTT Test results, see page 5.Centering RingSpiral Winding(Sealing Element)Centering RingSpiral WindingInner RingWinding Only8
