Milking machine liners are the only part of the equipment that touches the cow.
Designed to support hygienic milking routines and consistent liner performance.
Worn liners and cracked tubes can affect hygiene and routine performance. Selected liner materials and profiles are matched to the installed cluster and service plan.
Our optimized black dairy rubber liners maintain essential elasticity for 2,500 milkings, with service timing reviewed against the material, workload and visible condition.
Old rubber develops micro-cracks that harbor bacteria. Selected material and surface condition should be inspected as part of the farm hygiene and replacement routine.
Low-quality milk tubing stiffens in winter, causing kinks and severe vacuum drops. Our specialized formulation remains highly flexible even in extreme winter conditions.
For stable vacuum conditions, replacement liners should match the dimensions of the existing stainless steel or plastic shells. A complete milking cluster relies on the fit of these components:
The rigid outer casing that holds the liner and creates the pulsation vacuum chamber.
The critical flexible rubber/silicone interface that massages the teat and extracts milk.
Connects the liner and shell to the central claw, transmitting milk and vacuum.
The heavy-duty manifold that collects milk from all four quarters before sending it to the receiver line.
High-performance replacement liners and tubing designed for commercial milking systems.

Our replacement liners are engineered and designed for compatibility with major milking system brands including DeLaval, GEA, Boumatic, and Fullwood equipment.
Operating worn consumables can increase replacement-planning and hygiene-management risk; review liner condition, service interval and procurement timing together.
Aged liners can harden and lose elasticity, affecting fit and routine performance. Inspect liner condition as part of the replacement plan.
A 2,500-milking replacement interval can be used as a planning reference where it fits the liner material and milking routine. Inspect elasticity and surface condition regularly as part of the farm hygiene programme.
Butterfat can degrade rubber over time and create microscopic fissures. Include surface condition in routine inspection and replace liners when wear, cracking or cleaning results indicate it.
When the mouthpiece stretches out of shape, air leaks into the cluster (squawking). This causes vacuum instability and unit slip-offs. Operators must waste time re-attaching clusters. A correctly matched, well-maintained liner supports a stable seal and milk-flow path within the complete milking assembly.
Worn rubber can increase hygiene-management risk; replacement timing should follow liner condition, the farm routine and milk-buyer requirements.
Supporting B2B consumable supply with quantities, packaging and lead time confirmed for each order.
For commercial dairies milking thousands of cows, the liner replacement interval should follow the selected material, actual workload and inspection result. Bulk quantity and delivery planning are confirmed with the project order.
We manufacture vast quantities of food-grade milking cluster components for global agricultural equipment dealers. Our standardized sizing and stringent quality control allow compatibility to be checked against the current shell, claw and connection dimensions.
Review claws, pulsators, liners and vacuum conditions together when planning a replacement scope.

Match the replacement liner to the dimensions of the existing teat-cup shell and to the herd’s teat profile. This page offers round, triangular and square barrel options in NBR rubber or silicone; a photo of the shell, its part number and the current liner profile give the clearest basis for a compatibility review.
Black NBR rubber is the lower-initial-cost option listed for standard or seasonal herds, with a stated service reference of 2,500 milkings. Silicone has a higher initial cost and is listed with a 5,000+ milking reference plus stronger butterfat-degradation resistance. The appropriate choice depends on the operating routine, replacement plan and required liner profile.
Use the maintenance schedule for the actual material and operating conditions. The page lists 2,500 milkings for rubber liners and 5,000+ milkings for silicone liners; milk and pulse tubes should be inspected regularly. Replace components when the planned interval is reached or when inspection identifies deterioration that may affect the seal or flow path.
The range includes long milk tubes (LMT) plus twin or single short pulse tubes (SPT). Long milk tubes carry milk from the cluster, while the pulse tubes connect the liner and shell to the claw for the pulsation circuit. Confirm the existing claw and shell connections before selecting the tube configuration.
Replacement suitability can be checked for equipment from brands such as DeLaval, GEA, Boumatic and Fullwood, provided the shell, liner and connection dimensions are reviewed. Share the current component photos, part markings and measured connection points so the proposed liner and tubing can be matched to the installed cluster.
Provide the existing shell or cluster model, liner material preference, required barrel profile, tubing type and order quantity. For replacements, include photos or part numbers of the current shell, claw and tubes. This lets NexAgri prepare a quote around the configuration you actually need rather than a generic consumables list.
