The wellknown WEH® TK17 CNG has become a standard in almost every German fuelling station as well as in the surrounding European countries.
The single handed operation with the look and feel of a petrol or diesel nozzle has made it so popular.
The intergrated swivel joint and its light weight allows an ease of operation that can hardly be exceeded.
When disconnecting, the residual gas is vented automatically. This is WEH's attentiveness for safety in every step of operation.
WEH® TK17 CNG | How to handle
It's child's play. Only lift the fuelling nozzle from the dispenser. Place it onto the NGV1 receptacle and squeeze the actuation lever completely. The CNG nozzle will lock automatically, the pressure-tight connection is established and refuelling can start.
Description
WEH® Fueling Nozzle TK17 CNG for fast filling of cars (NGV1), single-handed operation - Product family
Field-proven Type 1 Pistol Grip Nozzle for CNG Fast Fill
Designed for fast filling of cars and light duty vehicles in self-service, the field-proven NGV1 pistol grip nozzle TK17 CNG has convinced customers worldwide for more than ten years with its sleek look and superior ease of operation.
The single-hand nozzle with the look and feel of a petrol nozzle is rated for two different pressure ranges 200 bar (3,000 psi – P30) and 250 bar (3,600 psi – P36). A color-coded impact protection for visual identification of the pressure range and a hand grip with magnet for activation of the dispenser means a further plus in convenience and user-friendliness.
Full 360° rotation makes for easy engagement with the vehicle’s fuel receptacle and the residual gas is vented via the gas recirculation when disconnecting the nozzle.

Temperature range
Is the temperature range in which the WEH® Product can be used.
Media temperature range
Is the temperature range of the medium used, which can flow through the WEH® Product (may change depending on the time of measurement).
Ambient temperature range
Is the temperature range of the environment in which the WEH® Product can be used.
Leak rate
Is the maximum external leak rate, which the WEH® Product exhibits in delivery condition.
Internal leak rate
The internal leak rate depends, among other things, on type of application, medium and pressure difference on the WEH® Product. On request it can be specified more precisely.
Max. side load
Is the max. allowable sum of all external forces that may act on the device under intended use.Note:External forces can affect the life time of WEH® Products and can cause damage. Tensile and transverse loads as well as vibrations and pressure impacts need to be considered, e.g. by user side measures such as on site mountings and similar. Therefore, lateral forces such as whipping hoses or other equipment must be avoided. WEH® Products should be installed in such a way, that lateral forces which could lead to leakage or damage can not occur.Special applications require a special consultation before selecting the product.
Products with pneumatic actuation
The customer has to ensure there is adequate axial movement when pneumatically actuated WEH® Products are used in automated systems, see maximum side load. Ideally the products should be mounted with a floating joint or introduced individually to prevent the possibly existing clamping jaws getting blocked or jammed in the thread of the test piece.
Sealing material
On request the WEH® Product can be adapted to customer specific applications regarding to the sealing materials used. The clarification of the media compatibility and suitability of the adapted WEH® Product for the final application is always the responsibility of the end user.
Storage / life time of components
There are certain requirements for every WEH® Product. WEH® Products are generally products which may be subject to wear and fatigue during operation and depending on your individual application/use. For details - in particular regarding the corresponding minimum inspection and maintenance intervals - please refer to the respective operating instructions for the WEH® Product.

Safe product selection
Our WEH® Products are designed to be operated by qualified professional users (insofar as WEH® Products are also designed to be operated by other users in individual cases, this is explicitly stated in the corresponding operating instructions). Please note that WEH does not know your system and therefore - also due to the large number of different potential applications of WEH® Products - cannot perform tests on all potential types of application. You alone are responsible for the selection, configuration and suitability of WEH® Products, especially according to the requirements of your system. Before purchasing WEH® Products, please particularly ensure that our products are compatible with your intended use, your performance data, your material and fluids, your system concept and your system limits according to our product specifications. Please also consider your technical and legal requirements for operation, handling and maintenance. The quality and safety of WEH® Products is our highest priority. For this reason, WEH® Products may not be used outside the specifications in the relevant data sheets and product descriptions. If you are not sure whether the WEH® Product is suitable for your system and intended use, please contact us in advance. We also strongly recommend that you refrain from using third-party spare parts or a combination of WEH® Products with unsuitable third-party products. You alone are responsible for reviewing the suitability of third-party products. WEH® Products and WEH® Spare parts comply with our quality and safety standards.
Explanation on the Pressure Equipment Directive
In general, WEH® Products with a maximum allowable operating pressure of more than 0.5 bar (PS) fall within the scope of application of the Pressure Equipment Directive 2014/68/EU, are generally classified as pressure accessories in accordance with Article 2 (5) of the same and are considered to be similar to piping. These WEH® Products may not be used as safety accessories. Furthermore, it is pointed out, that these WEH® Products are designed and placed on the market in accordance with the requirements of Article 4 (3) of the Pressure Equipment Directive 2014/68/EU.
For some products a different classification and/or categorisation is required or can be conducted on request. In these cases, a conformity assessment procedure in accordance with Annex III of the Pressure Equipment Directive 2014/68/EU can and will be conducted (if legally required) and the conformity can be declared by means of an EU Declaration of Conformity in accordance with Annex IV of the Pressure Equipment Directive 2014/68/EU. In these cases, the EU Declaration of Conformity is enclosed with the product.
External change management
WEH reserves the right to update, optimise and adjust its products continuously. This may result in corresponding changes of the product. Customers will be informed proactively or unsolicited by WEH only in individual cases about product updates, product optimisations and/or product adaptations that have been carried out.

Application
Fueling nozzle for CNG fast filling of cars at self-service fueling stations to be used with WEH® Receptacles acc. to NGV1 standard and ISO 14469.
Field-proven single-handed filling nozzle for safe & easy CNG refuelling
Well-known dispenser and station manufacturers worldwide use successfully for more than 10 years the famous NGV1 Fueling nozzle Type TK17 CNG. The Pistol Grip Self-Service Nozzle is designed for high-flow public and private compressed natural gas fueling systems. Applications include quick-fill, self-service fueling of automobiles, light trucks, shuttle buses and vans.
The nozzle will not dispense CNG until securely engaged onto an appropriate receptacle. When fueling is complete, squeeze and release the lever to automatically stop the flow of gas into the vehicle, vent the trapped gas and release the pistol grip nozzle from the receptacle.
