Dairymaster Swiftflo Claw Pulse Block (4 x 1) The Dairymaster Swiftflo Claw Pulse Block (4 x 1) is a replacement pulsation air distribution block designed specifically for use within Dairymaster Swiftflo claw assemblies . This pulse block helps route pulsation air evenly to all four teat cup liners in a “4 x 1” configuration, contributing to consistent liner movement and stable vacuum performance throughout the milking cycle. Correct pulsation distribution is essential for efficient milking, good teat condition, and dependable herd performance. If the existing pulse block becomes blocked, cracked, or worn due to prolonged use or contamination from milk residues and cleaning chemicals, it can lead to uneven pulsation, reduced milking efficiency, and increased stress on liners and vacuum components. The Dairymaster Swiftflo Claw Pulse Block (4 x 1) is ideal for servicing, repairs, or preventative maintenance , particularly where pulsation performance has become inconsistent or the existing block shows signs of deterioration. Replacing this component helps restore balanced air delivery to the liners, supporting smooth, efficient milk-out and prolonging the service life of the claw ass
