Requires additionalrod length which is determined bythe cylinder stroke.Low Breakaway PistonA low breakaway piston reducesrunning friction and utilizes abronze-filled Teflon wearband with abi-directional, o-ring energized,bronze-filled Teflon piston seal.1/8" NPTFDrainback PortsDrainback ports are used to returnfluid to the tank that accumulatesbetween the rod seal and rod wiper.Port position No. 1 is standard withalternate locations at 2, 3 and 4. 1 /16"NPTF is standard on 5 /8" and 1"diameter rods. 1 /8" NPTF is standardon larger rod diameters.Air Bleeders1/8" NPTF bleeders are located inthe tube or in the head and capwhen specified. SAE #2 bleederslocated in the head and cap arealso available when specified. Allbleeders may be located in positions1, 2, 3 or 4.Special Rod EndsModifications of standard rod ends or completely special rodend styles are available to meet unique rod end connectionrequirements. (See page 33 for standard rod ends.)Special PortsMetric, BSP, Manifold, Flange and other porting options areavailable to meet specific requirements. (See page 24.)Extra Heavy Chrome Tubes and RodsAdded wear and corrosion resistance are available by specifyingExtra Heavy Chrome (.002" to .003" thick).PlatingElectroless Nickel, Cadmium and other plating finishes areavailable for corrosive, washdown, pharmaceutical, and otherapplications.Stainless Steel Piston RodsPiston rods in 300 and 400 series and 17-4 PH stainless steelare available for those applications requiring increased corrosionresistance.Special Coating and PaintingCylinders can be prepared with a primer coat or epoxy, lacquer,or enamel paint finish coatings to customer specifications.Synergistic, Nitrocarburizing and other material treatmentsare also available for special applications.Special MaterialsBronze rod cartridges, complete stainless steel cylinders orother special materials are available to meet most uniquematerial requirements.5
