Protect Udder Health.
Lower Somatic Cell Counts.
Milking machine liners are the only part of the equipment that touches the cow.
Ensure gentle milking, eliminate costly slip-offs, and maintain strict hygiene standards with our heavy-duty replacement liners and silicone tubing.
Why Commercial Dairies Choose Our Milking Liners
Worn liners and cracked tubes are the silent killers of milk quality. Engineered materials ensure safe, complete milk-outs.
Milking Lifespan
Our optimized black dairy rubber liners maintain essential elasticity for 2,500 milkings, ensuring the mouthpiece retains a tight, vacuum-stable seal without squawking.
Reduced Bacterial Adhesion
Old rubber develops micro-cracks that harbor bacteria. Our precision-molded smooth antimicrobial surface drastically reduces plate counts and prevents butterfat absorption.
Cold Weather Flexibility
Low-quality milk tubing stiffens in winter, causing kinks and severe vacuum drops. Our specialized formulation remains highly flexible even in extreme winter conditions.
Where Do Liners Fit?
Milking Cluster Components Overview
To ensure optimal vacuum stability, your replacement liners must perfectly match the dimensions of your existing stainless steel or plastic shells. A complete milking cluster relies on the precise synergy of these components:
The Shell (Teat Cup)
The rigid outer casing that holds the liner and creates the pulsation vacuum chamber.
Milking Machine Liner (Inflation)
The critical flexible rubber/silicone interface that massages the teat and extracts milk.
Short Pulse & Milk Tubes
Connects the liner and shell to the central claw, transmitting milk and vacuum.
Milking Claw
The heavy-duty manifold that collects milk from all four quarters before sending it to the receiver line.

Universal Compatibility
Our replacement liners are engineered and designed for compatibility with major milking system brands including DeLaval, GEA, Boumatic, and Fullwood equipment.
The Commercial ROI of Routine Replacement
Operating worn consumables costs exponentially more in veterinary bills and lost milk premiums than the price of fresh replacement liners.
1. Udder Health & SCC Control
Aged liners become hard and lose their ability to properly massage the teat. This leads to teat-end hyperkeratosis (callusing), preventing the sphincter from closing tightly after milking.
Replacing liners strictly at 2,500 milkings ensures optimal elasticity, reducing environmental bacteria entry and drastically lowering bulk tank Somatic Cell Count (SCC), securing your factory milk quality premiums.
2. Hygiene & Mastitis Prevention
Butterfat naturally degrades rubber over time, creating microscopic fissures on the liner's inner barrel. These cracks are impossible to sanitize effectively with automated CIP systems and act as breeding grounds for mastitis-causing pathogens like Staphylococcus aureus, leading to severe cross-contamination between cows.
3. Milking Efficiency & Throughput
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. Fresh rubber grips the teat firmly, ensuring fast, complete milk-outs and maintaining high parlor throughput speeds.
Cost of Delaying Replacement
Elevated SCC from bacterial buildup in cracked rubber directly reduces factory payout rates.
