The sealing forces could come from either spring deflection at low pressure or the system itself at high pressure to ensure full contact with the gland surfaces. In dynamic applications, the spring also provides resiliency to the seal jacket from inside out, compensating for material wear, jacket wall reduction, and eccentricity. The seal designs combined with the variety of high performance jacket materials provide the optimum sealing performance in a wide range of tough-to-seal environments.Plastic seal jacket materialsMaterial CodeCompound Features & Recommended ServiceChemicalWear10Virgin PTFE, premium grade, excellent material for gases and cryogenic applications, excellent chemical resistance, FDA approved, API 6A qualifiedEP9Modified PTFE, improved creep and extrusion resistance, excellent for static applications, low gas per_x005fmeability, good cryogenic properties, moderate to high vacuum service, FDA approved, API 6A qualifiedEF16Fiber Glass/Moly filled, excellent wear and creep resistance, good abrasion resistance for sealing non_x005f_x0002_lubricated media, good extrusion resistance, highly wear resistant blend, API 6A qualifiedEE15Carbon/Graphite filled, suitable for dynamic sealing of steam and water as well as poorly lubricated, recommended for dry or insufficiently lubricated applications, API 6A qualifiedEE21Graphite filled, very low coefficient of friction, good for water service, excellent for dry or poorly lubricated applications, API 6A qualifiedEF6Carbon Fiber filled, excellent wear and creep resistance, good electrical conductivity, good in water service, API 6A qualifiedEE80Mineral filled, used for sealing food products, good wear properties for both rotary and linear applications, FDA compliant material for sanitary food and pharmaceutical processingGG88Ekonol filled, good wear resistance but is not abrasive against non-hardened surfaces, should not be used in steam applications, best in dynamic applications running against soft metalsGG35Stainless Steel filled, excellent material for steam service, good compression strength proportion along with better chemical resistance than bronze filled PTFEFG1Bronze filled, suited for high speed dynamic sealing of lubricating media, should not be used for chemical servicePE2Polyimide filled, excellent wear resistance but not abrasive against non-hardened surfaces, should not be used in steam applicationsGE24Virgin PEEK, high strength material predominately used for anti-extrusion devices, such as back-up ring and support ringsGG23Carbon Fiber filled PEEK, improved high temp properties, extremely rigid, high strength material used for back-up rings, guide rings, and support rings, API 6A qualifiedGG22PTFE filled PEEK, lower coefficient of friction than virgin PEEK, excellent high heat and wear resistance, chemically resistant to aggressive environmentsGE26UHMW, best material for reciprocating service in water or water based fluids, typically used for sealing food products, paints, adhesives , excellent wear and abrasion resistanceGE101ETFE, melt processible fluoropolymer with good impact, abrasion and wear resistance, used in applica_x005ftions where gamma radiation resistance is required, superior to nuclear radiationFEE - excellent, G - good, F - fair, P - poormetal spring materialsMaterial CodeNameDescriptionA301 Stainless SteelGood corrosion resistance for general applicationsBInconel 718For extreme temperatures.
