Corken offers a variety of piston rod packing configurations, distance piece options, and special coatings suitable for a wide range of industrial gases. A double packed (D-Style) reciprocating compressor has one distance piece and offers a moderate level of leakage containment. A triple packed (T-Style) compressor has two distance pieces offering the highest level of leakage control. If necessary each distance piece can be pressurized, purged, or vented for maximum leakage containment. Both styles are available in single- and two-stage, air or water cooled, and single and double-acting versions with NPT or Class 300 RF connections.
Double Packed Reciprocating Compressors (Oil Free)
• Utilizes two sets of V-ring packing per piston rod and one distance piece
• Adjustable packing screw on lower packing maximizes sealing performance over the life of the packing
• Oil-free gas compression (exceptions: models 791 and 891 are not oil free)
• Typically used in toxic and corrosive applications where oil-free gas is required and moderate leakage containment is desirable

Triple Packing Reciprocating Compressors (Oil Free)
• Utilizes three sets of V-ring packing per piston rod and two distance pieces
• Adjustable packing screw on lower packing maximizes sealing performance over the life of the packing
• Oil-free gas compression
• Typically used in toxic and corrosive applications where oil-free gas and maximum leakage containment are critical
