O-ring for KEG taps

Suitable for KEG closures of types A, M, S, and D
Wear part – must be serviced regularly and replaced if necessary

1. Function of the O-ring

The O-ring for the KEG closure stem plays a central role in ensuring that the keg system is tightly sealed. As a rule, two O-rings are installed on the inside of the keg body to ensure that the spiget slides smoothly when pressed down and at the same time ensures a secure seal. These O-rings prevent gases or liquids from escaping uncontrollably and ensure that the KEG system functions optimally.

2. Compatibility

Variant 1: O-ring for KEG closures type A (flat cone) and M (combination cone)
variant 2: O-ring for KEG closures type S (basket cone) and D (cup cone)

3. Design and function

The O-ring is usually made of a robust rubber material that ensures a perfect seal between the stopper and the keg body. When the spigot is pressed down, it slides along the inside of the keg body and is guided by the O-rings. The elastic properties of the O-ring create an optimal seal that prevents pressure or liquid from escaping.

4. Wear and maintenance

The O-ring is a wearing part that can wear out over time due to pressure, temperature, and frequent use. Regular maintenance is therefore essential to ensure the long-term functionality of the KEG system.

maintenance:

Greasing: It is recommended to grease the O-ring regularly to reduce friction and extend its service life.
inspection: Make sure that the O-ring is in good condition. Cracks or signs of wear can impair the sealing ability.
Replacement: If the O-ring is damaged or heavily worn, it must be replaced to prevent leaks and pressure loss.

5. O-ring variants

There are two variants of the O-ring, each suitable for different KEG closures:

Variant 1:
- For KEG closures type A (flat cone) and M (combination cone)
- These O-rings are the right size and shape to fit in flat cone and combination cone closures and reliably seal the connection between the stem and the keg body.
- Particularly suitable for standard models of kegs that use flat seals.
Variant 2:
- For KEG closures type S (basket keg) and D (cup keg)
- These O-rings are designed for basket keg and Köpikeg closures and also ensure reliable sealing and guidance of the spigot.
- These types are more commonly used in industrial or large brewery systems.

6. Advantages of the O-ring

reliable sealing: The O-ring ensures a perfect seal between the stem and the keg body, preventing pressure loss and liquid leakage.
durability: With proper maintenance and care, the O-ring can provide consistent performance over a long period of time.
easy handling: The O-ring is easy to install and replace, making it a practical spare part for KEG operations.
flexibility: The two available versions cover a wide range of KEG closures, making the O-ring a universal replacement part for different KEG systems.

7. Application and installation

step 1: Carefully remove the old O-ring (if damaged or worn) from the inside of the keg body.
step 2: Select the appropriate O-ring (depending on the type of KEG closure) and check that it is the right size and fit.
step 3: Insert the new O-ring into the inner handle of the keg body and make sure it is seated correctly.
step 4: Lightly grease the O-ring (optional) with a suitable grease to improve sliding and extend service life.
step 5: After installation, check that the handle slides smoothly and that the seal is working correctly.

8. Cleaning and maintenance

regular inspection: Check the O-ring regularly for wear, cracks, or deformation that could impair the sealing effect.
cleaning: Clean the O-ring carefully with warm water and a mild detergent as needed. Avoid harsh chemicals that could damage the material.
greasing: Apply a small amount of food-grade grease or silicone grease to the O-ring regularly to maintain its lubricity.
