Everything You Need to Know About Keg Fittings

Keg fittings (spears) are special connectors and valves used to connect beer kegs to tapping systems. They allow for the safe and hygienic dispensing of beer from the keg. There are different types of fittings that vary depending on the region and type of beer. It is crucial to choose the correct keg fittings for each keg to ensure that the dispensing process is efficient and hygienic. Brewery staff should familiarize themselves with the various types of keg fittings to make the best choice for their brewery. The most common types of fittings are:

FITTING SYSTEMS

A-System Fitting (Flat Fitting or Key Keg Fitting): Commonly used in Europe, the A-System is a flat design slide coupler with a round flange. The fitting is made of high-quality nickel-plated brass and a stainless steel probe. All parts that come into contact with beer are stainless steel to avoid any metallic taste.
G-System Fitting (Grundy): Used primarily in the UK, the G-System is similar in structure to the A-System but differs in its triangular housing design instead of a round one. It is applied and then twisted into place.
S-System Fitting (European Sankey): This system is common in Europe and is similar to the American Sankey fitting. It can be recognized by its basket-like housing. The fittings are made of stainless steel for maximum stability and hygiene and feature a dual valve function for fast filling.
M-System Fitting (Combo Fitting): Less commonly used and designed for certain beers and regions, M-System fittings combine features of flat and basket fittings. Internally, they resemble basket fittings, while their housing is designed after flat fittings for their hygienic benefits. From the top, they appear as flat with a "bulb" in the center.

A, M, and G fittings are more hygienic than the S-System because dirt and beer residue can accumulate more easily in the S-System’s basket.

Special tools are required for installing and maintaining fittings, such as decompression keys, disassembly tools, and assembly guns.

CO2 gasket color coding helps with manual or camera-based separation of kegs for routine maintenance.

Stainless Steel Fittings - Threaded or Threadless?

Stainless steel fittings can come with or without threads, depending on brewery needs. Threaded fittings are generally easier to install and are advantageous in situations requiring disassembly for maintenance or adjustments. However, they also need careful sealing to avoid leaks. Threadless fittings offer a secure connection without the risk of human error.

Choosing between threaded and press fittings depends on your specific project and requirements. Both types are available in high quality and adhere to international standards.

An example is the RS-SOS, a basket fitting without threads. It is fixed in the keg with a safety ring, also called a snap ring or C-clip. Once installed, it can be identified from above by its notch and the safety ring.
These fittings ensure beer is dispensed from the keg without contamination and at the right pressure. They are a critical part of beer filling and dispensing systems.

- To extend the life of your keg fittings, regularly check all seals and O-rings for wear and replace them as necessary. Lubricate moving parts like valves and couplings with a special lubricant to ensure smooth operation.

By regularly cleaning and maintaining your keg fittings, you can ensure that your beer stays fresh and delicious.

FITTING SERVICE EXAMPLE: RAUSCH & PARTNER GMBH

Used kegs are delivered to the warehouse. The fitting is unscrewed from the keg using manufacturer-certified tools. The fitting is then disassembled for visual inspection of individual parts. Worn parts (e.g., springs, seals, and plates) are replaced. Upon request, stainless steel parts can also be cleaned in an ultrasonic bath with a special solution. After cleaning, the fitting is reassembled with new seals and possibly new replacement parts.

The manufacturer-specified fitting length is checked and adjusted if necessary. Afterward, the fitting is mounted onto the cleaned keg and tightened with 70-80 Nm. Finally, the fitting undergoes a pressure test (2 bar) to ensure it is leak-proof.

HOW TO CONNECT THE FITTING TO THE TAP HEAD

To connect the fitting to the tap head, first ensure both parts are compatible and belong to the same system (e.g., S-System). Fittings and tap heads usually have threads that allow them to be easily screwed or slid together. First, screw the fitting into the corresponding thread of the keg. Then, screw or slide the tap head onto the other end of the fitting. Make sure the connection is tight and secure to prevent leakage. Once the connection is established, the beer or liquid can be dispensed through the tap head.
