3 Anode Connector - An optional connection provided for attachments of an anode to the coupling, normally on thebody or middle ring. Armor - A metallic gasket tip providing conductivity between the middle ring and follower as well as protection fromattack by severe line content. Bolt and Nut - Provides means of compressing a bolted coupling, providing seal or seal and restraint, depending oncoupling design. Compression Nut - The component that compresses the gasket and grip ring by tightening on to the body ofthreaded compression couplings and fittings. Follower - Ring that retains the gasket and provides a means to compress the gasket and grip ring in boltedproducts.

4 Follower Insulator - A high dielectric annular sleeve formed to prevent conductivity between the pipe and couplingon the insulating pipe end. Gasket - Sealing component which is compressed upon installation, providing a Pressure seal. Can be insulatingor conductive. Grip Ring - Holds the pipe against pullout in couplings made for seal and restraint. Insert Stiffener - A tubular reinforcement sleeve used on all polyethylene pipe ends to prevent pipe collapse. Insulator - A high dielectric cylindrical sleeve preventing electrical shorting between the pipe and middle ring. Middle Ring or Body - Pressure containing component that bridges the gap between pipe ends.

5 Pipe End Separator - A high dielectric ring which prevents shorting from pipe end to pipe end. Retainer Cup - Component that retains the gasket in a threaded compression specific product applications, see the detailed information in the Dresser Gas Market product Application Guide 1 BODYCOMPRESSION NUTINSULATORPIPE END SEPARATORINSULATINGGASKETARMOREDGASKETRE TAINER CUPFOLLOWERBOLTNUTMIDDLE RINGINSULATORPIPE END SEPARATORINSULATINGGASKETARMOREDGASKETBO LTFOLLOWERNUTGASKETMIDDLE RINGS tyle 38 Coupling(Provides Seal Only)BODYRETAINER CUPCOMPRESSION NUTGASKETSEAL ONLY PRODUCTSSeal Only - Current product Line: Style 38, 39, 40, 39-40 and 39-62 Couplings Style 63 Expansion Joints Style 60 and 160 Bell Joint Clamps Style 128 Flanged Adapters Style 88 and 90 FittingsStyle 90 Fitting(Provides Seal Only)2 Seal Only - Insulating ProductsStyle 90 Insulating Coupling(Provides Seal Only)Style 39 Insulating Coupling(Provides Seal Only)Dresser insulating product designs are available to electrically isolate sectionsof piping for cathodically protected systems.
