Compatible Boumatic Flex 60 – Pack of 4 (Non-Vented) The Compatible Boumatic Flex 60 – Pack of 4 (Non-Vented) are pattern replacement milking liners designed for use in clusters that require Flex 60 specification liners without venting. These liners are engineered to match the size and function of original Boumatic Flex 60 non-vented liners, supporting consistent vacuum performance and smooth milk flow. Each liner in this pack measures 303mm in length , ensuring the correct geometry for smooth milk transfer during milking. The 25mm hole head and 11mm connection are manufactured to closely match original specifications, providing a secure fit within compatible shells and clusters. Accurate sizing helps reduce liner slip, maintain correct pulsation characteristics, and support effective milking. As non-vented liners , these are suitable for systems where air admission into the liner is managed externally through the cluster design rather than through the liner itself. This can assist with stable vacuum delivery and may suit certain parlour configurations or producer preferences. Supplied as a pack of 4 , the Compatible Boumatic Flex 60 – Pack of 4 (Non-Vented) are ideal for replacing
