Parker Hannifin JJ2HLT142AC Pneumatic Cylinder. This Parker unit is a Series 2H pneumatic cylinder with a 2.750-in bore, identified by the model JJ2HLT142AC. In pneumatic systems, cylinders convert compressed air into linear motion for automation tasks, and a 2.750-in bore provides greater piston area for higher potential force at a given pressure. The part number JJ2HLT142AC uniquely identifies this configuration within Parker’s JJ2H cylinder family.
