LPG is a versatile energy source for camping, barbecues or the gas cooker in the kitchen. It is used in gas hobs, radiant heaters, but also in small and large gas barbecues for camping or stationary use. Either way, the following always applies: a secure connection between gas hoses and appliances is crucial.
The GOK plug-in coupling type SKU-QR allows you to connect hose lines to mobile gas appliances without tools. It is compatible with standardised plug-in nipples (STN), which guarantee a tight connection. The automatic gas lock of the SKU-QR interrupts the gas flow when uncoupling and minimises the risk of gas leaks. Find out how to make optimum use of the GOK plug-in coupling type SKU-QR.

What is the plug-in coupling type SKU-QR?
The plug-in coupling type SKU-QR from GOK enables the quick, tool-free connection of hose lines to gas appliances in outdoor areas up to an operating pressure of 5 bar (PS5). It is therefore often referred to as a gas quick coupling or gas quick connector.
The SKU-QR plug-in coupling for quick connection of hose lines to gas appliances without the use of tools.
Target group: Private users in the field of liquid gas applications
It is aimed at private users who use liquid gas in the garden, when camping or when travelling with a motorhome, caravan or van. However, it is equally interesting for commercial users. The following applies to both private and commercial users: The more gas appliances in use that are to be supplied from one gas cylinder at different times, the more interesting the use of a plug-in coupling such as the SKU-QR becomes.
Overview of typical areas of application (camping, caravanning, barbecues)
Typical areas of application are the connection of gas barbecues, camping cookers and radiant heaters in outdoor areas. The SKU-QR is ideal for all outdoor LPG applications where users require a flexible and safe gas connection. In conjunction with a GOK supply flap, this also makes it easy to connect outdoor appliances.
Where is it not permitted?
Gas cookers in the home must not be connected with the plug-in coupling. Gas cookers have special requirements, a fixed installation and other connections, which is why the plug-in coupling is not permitted here.
It is also not permitted to use the plug-in coupling within the permanently installed pipe system of a motorhome, caravan or van. However, if you have installed a so-called external gas socket (GOK Variant supply flap), for example, you can use the plug-in coupling type SKU-QR outdoors when camping without hesitation.
The plug-in coupling type SKU-QR must not be used, for example, in residential buildings for the operation of gas cookers or gas hobs. Image generated with the help of DALL-E / ChatGPT from OpenAI.
Structure of the SKU-QR plug-in coupling
The SKU-QR plug-in coupling system consists of the plug-in coupling itself, which is firmly and securely connected to the gas hose. The SKU-QR has a rubberised grip surface for easy operation. Users also need the ‘counterpart’ to the plug-in coupling, a so-called plug-in nipple (STN), which is connected to the gas appliance.
If the two parts are not connected, users should protect the plug-in coupling with the attached sealing plug so that no dirt particles or small animals can get in.
The SKU-QR plug-in coupling consists of the plug-in coupling (right) itself, which is connected to the gas hose, and the “counterpart” (left), the plug-in nipple, which is connected to the gas appliance.
How it works: Safe gas hose connection made easy
When the plug connection is disconnected, the gas flow is automatically interrupted. This is achieved by an integrated gas lock that closes automatically when the connection is disconnected, preventing gas from escaping.
Compatibility with standardised plug-in nipples (STN)
The SKU-QR is compatible with standardised plug-in nipples (STN), which ensures a secure and tight connection to a wide range of gas appliances. Important: The plug-in coupling type SKU-QR does not serve as a shut-off device, but must always be used in conjunction with a shut-off valve (e.g. gas cylinder valve or GOK supply flap).
Even though the gas plug-in coupling is an extremely safe system, carry out a regular leak test with a leak detection spray to ensure that there are no gas leaks. Leaks can lead to dangerous situations and must be rectified immediately.
Step-by-step installation instructions: Connect the gas hose securely
Connect the hose line to the SKU-QR plug-in coupling.
Screw a suitable plug nipple (STN) onto the gas appliance and connect the hose line to the SKU-QR plug-in coupling.
Push the plug-in coupling onto the plug-in nipple until you hear it click into place.
Open gas cylinder, carry out leak test.
Open gas cylinder, carry out leak testCompliance with legal regulations and recommendations
When installing and using the plug-in coupling, observe the applicable legal regulations and safety standards for LPG systems. You can find more information in the enclosed installation and operating instructions.
Advantage: Tool-free operation saves time and effort
The GOK push-fit coupling SKU-QR enables quick and easy connection of gas hoses to different gas appliances without additional tools. No more need for a spanner to tighten the nut. This saves time and effort, especially when frequently changing gas appliances.
Thanks to the SKU-QR plug-in coupling, operators of LPG systems can create a tight and secure connection between the gas hose and gas appliance in next to no time with just one click.
Advantages at a glance
Tool-free assembly – no spanner required after initial assembly
Automatic gas lock – stops the gas flow immediately when uncoupling
Benefit: Increased safety thanks to automatic gas shut-off when uncoupling
The integrated gas shut-off provides additional safety by automatically interrupting the gas flow when uncoupling. This minimises the risk of unintentional gas leaks.
Advantage: Flexibility through easy handling in different scenarios
Users who own more than one gas appliance are familiar with the problem of different connections. GOK offers plug-in nipples (STN) with different screw connections that can be screwed onto the respective connections. This allows you to switch between gas appliances quickly, safely and easily using a plug-in coupling, a hose, a pressure reducer and a gas cylinder – without any tools. This offers maximum flexibility when camping, barbecuing or other outdoor activities.
The plug-in coupling type SKU-QR with various plug-in nipples can be individually configured for your purposes and connections.
Summary
The GOK push-fit coupling SKU-QR offers a safe, flexible and time-saving solution for connecting gas appliances outdoors. The tool-free operation, automatic gas shut-off and compatibility with various plug-in nipples make it an indispensable accessory for many liquid gas applications.
Whether for quickly switching between barbecues and radiant heaters when camping or for the flexible use of different gas appliances in the garden – the GOK SKU-QR plug-in coupling is an investment in greater convenience and safety when using liquid gas.

FAQ – Connect gas appliances quickly
The SKU‑QR is a standardised quick-release coupling by GOK that allows fast, tool-free connection of gas hoses to gas appliances such as barbecues, camping cookers or patio heaters. It minimises time and tool requirements and integrates an automatic gas shut-off.
When disconnecting, the integrated shut-off device ensures that the gas flow is immediately stopped – as long as the coupling and plug nipple are not correctly connected, the line remains sealed.
The coupling works with all STN plug nipples according to standards, e.g. STN x G 1/4 LH UNF, STN x RST 8 or G 5/8 UNF. This ensures flexible use.
No. The coupling serves solely as a connecting element and is not a substitute for a shut-off valve. A separate shut-off valve at the cylinder valve is still required.
The article points out that certain areas of application are excluded; please check individual national regulations and operating instructions – mobile applications such as camping, BBQ or household are generally permitted, whereas stationary continuous use is usually excluded.
