Beer hose nozzle – straight or curved, with collar and attachment

The beer hose nozzle – available in straight or curved versions – is a key connecting element in beverage and dispensing system technology. It is used to connect flexible beer or CO₂ hoses securely and tightly to threaded connections, fittings, or valves. The version with collar and neck not only ensures that the hose is securely seated, but also prevents it from slipping off under pressure or when subjected to tensile stress.

These grommets are available in various sizes and are optimized for professional use in beverage lines – especially for beer dispensing systems, CO₂ lines, and cleaning installations in the catering and brewing industries.

Design and construction

The hose grommets are available in two designs:

Straight grommet: Used where a direct, linear hose run is desired – ideal for tight, structured installations.
Curved nozzle (angled nozzle): Suitable for confined installation conditions or where a change of direction is required – e.g., for tank connections or under counters.

All versions feature:

A collar: A circumferential thickening behind the hose rib that prevents the hose from slipping.
A smooth zone for easy screwing or insertion into couplings or adapters.

Materials

Nickel-plated brass:
Most of the grommets are made of nickel-plated brass – a durable, robust, and food-safe material. The nickel plating reliably protects the brass from corrosion, especially when in contact with moisture, CO₂, and cleaning agents.
Stainless steel (only for 4 mm grommets):
The particularly small 4 mm grommet is made of stainless steel to ensure maximum strength with a minimum cross-section. Stainless steel is also highly resistant to aggressive media and is ideal for CO₂ or special lines.

Dimensions and application notes

The size specifications for the grommets always refer to the inner diameter of the hose used. This is particularly important for a secure and tension-free connection:

Grommet size	Suitable hose (inner diameter)	Typical hose outer diameter
4 mm	For very thin CO₂ hoses	8
6.7	For special connecting lines	9.5
7	Standard size for CO₂ and beer lines	12
10	For larger volume flows	15/16

Important: The grommets must always be selected to match the inner diameter of the hose – for example, a 7 mm grommet is only intended for hoses with an inner diameter of 7 mm. A fit that is too tight or too loose can lead to leaks, material damage, or unsafe connections.

Areas of application

Dispensing systems (beer, lemonade, CO₂)
Connection of hoses with fittings, keg couplings, cleaning equipment
Pressure lines for CO₂ or beer gas
Cleaning and testing systems
Temporary or permanent connections in mobile bars or cold rooms
