Liner & Shells
The right choice makes the different
When it comes to selecting the right liners for your milking parlor, just remember this:
Size + Material + Shape.
Because one size definitely does not fit all...
FIRST THINGS FIRST: SIZE MATTERS!
The correct liner size is critical for proper milking performance. Length and diameter must match the teats of your herd. A liner that fits a Holstein-Friesian may not be suitable for a Simmental, for example.
A correctly fitted liner ensures an optimal vacuum seal, enabling gentle yet thorough teat massage. With the perfect fit, you benefit from:
- Consistent vacuum stability for ideal milking performance
- Reduced mastitis risk through hygienic, gentle handling
- Minimal teat-end stress, lowering the chance of hyperkeratosis
- Secure teatcup attachment, minimizing slips and fall-offs
GEA offers a wide range of liners tailored to your herd and milking system – for maximum efficiency and animal comfort, every day.
Second: Material Selection
Silicone vs. Rubber – Key Performance Differences
The main distinction between silicone and rubber liners lies in their service life:
- Rubber liners: up to 2,500 milkings
- Silicone liners: up to 5,000 milkings
Silicone liners are ideal for farms aiming to reduce replacement frequency and maintenance effort. Both materials are tested by GEA for:
- Mechanical durability
- Resistance to butterfat, detergents and disinfectants
- Hygienic, smooth milking performance
GEA liners are developed based on the expertise of experienced dairy professionals – tailored to ensure optimal performance, durability, and animal health.
Liner Barrel Shapes – What´s inside matters
Cylindrical or Conical?
The right barrel shape depends on your herd:
- Cylindrical: suited for uniform teat shapes
- Conical: adapts better to variation – ideal for mixed herds
Round or Non-Round?
- Round liners fully enclose the teat for secure grip and steady milk flow
- Non-round liners reduce pressure on the teat canal – helpful for herds prone to hyperkeratosis
GQ Liner – Smart Hybrid Design
The GEA GQ liner combines the advantages of different shapes (Conical, Round and Square). Gentle massage, secure fit, minimal air leakage – for efficient and gentle milking.

— Ludennec Family, Plouha, France | The Ludennec family upgraded their 2x12 Side-by-Side rapid exit system for 120 cows with our Classic Conical Medium Rubber liners. The new setup is lighter, more flexible, and has streamlined their routine — saving over 10 minutes per shift.

"We experience much less reattachment and much faster milking."
