WEH® TW800 | Diverse application possibilities

The WEH® TW800 Quick Couplings are ideal for low pressure testing of automotive component at vacuum or pressures up to 50 bar, i.e.supply lines for cooling water, heating water, oil, etc. and for function testing of pressure vessels, cooling systems, hoses and tubes.
WEH® TW800 | Function

The quick release coupling TW800 is easy to use. Only pull back the grip sleeve and push the WEH® Quick Disconnect onto the test piece as far as the stop. Then push the grip sleeve forward, the clamping jaws are locked and the pressure-tight connection is made. Testing can now proceed by supplying the pressure medium.
WEH® TW800 | ConnectionPossibilities

TW800 for function and pressure tests on components with a bead, rim, collar, flange, stub or external thread. The WEH® TW800 is rated for a pressure range of up to max. 50 bar.

Description

WEH® Connector TW800 for testing of bead, rim, collar flange, stub or male thread, grip sleeve actuation - Product family

The WEH® TW800 Quick Connector is ideally suited for function and pressure testing within the low pressure range up to 50 bar max. He establishes a leaktight connection to components with bead, rim, collar, flange, stub or male thread in just seconds - without tedious hand tightening. Additional sealants and sealing tapes are not required.

Simply pull back the grip sleeve and place the connector onto the test piece port. Thanks to the time-saving handling, testing times are significantly reduced and workflows facilitated. The high flow rate ensures, in addition, an enhanced productivity at the test bench.

Made from high quality stainless steel, the connector meets the high demands of industrial testing and is also suited for automated test procedures.

In the automotive industry, the WEH® TW800 quick release coupling is also used for leak testing of fuel connections, connections for cold and hot water and other supply lines as well as refrigeration and air conditioning components.

Term	Definition
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.

Subject	Definition
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.

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. You are free to contact WEH at any time to request information about any product updates, product optimisations and/or product adjustments.

Quick connector for pressure and function testing of components with a bead, rim, collar, flange, stub or male thread at low pressure ranges for the following standard sizes:

Beads for hose connections
Whitworth tube thread to DIN EN ISO 228-1 | G1/2" up to G3/4"
SAE J514 JIC 37° | UNF 7/16"-20 up to UNF 7/8"-14

For automotive applications, the TW800 is used for testing fuel lines, radiators, ACR components and other sub-assemblies for the automotive industry.
It is also used in electromobility for testing e-axles, cooling water pipes of electric machines and electric motors.
Another application is function testing compressors, heat exchangers, measuring devices, hoses, tubes and tanks. The test connector is also an ideal tool for automated leak testing during production, automatic systems and robotics.
