Nolek AB

We are the world’s leading total solution provider of leak testing, proof testing, leak detection, helium charging and recovery and non-destructive testing equipment. Leak detection today is used in many applications from heavy industrial requirements such as found on oil platforms to the most demanding applications in the medical, science and space related field. Each of those require tailored solutions and instruments. Additionally all applications required more stringent specifications and have to meet international standard. While many applications look standard from the onset, they appear to be more complex in nature and require different test modes or even product alterations by the user. This as their products form a physical point of view do not allow the needed test method.

We started working with leak detection and leak testing way back in 1973 – and since then we have served countless customers over the globe – many of whom are long-term clients.

When our clients say why they choose us for their projects they say that our attention to detail, flexibility and service-mindedness are key factors that make it easy. Because we are passionate about what we do and sharing our knowledge of the leak testing and detection industry we run courses for our clients – it’s crucial that whatever needs they have, and whatever machine or software we have built for them, that there is a full understanding of how to operate it and how to get the most production out of it.

From our perspective the most important factors in delivering a quality service and product to our customers cover quality, and a partnership mentality.  Many leak applications and products look deceptively simple once in full operation, but it is the partnership mentality and approach that both we and our clients bring to the table that drives this simplicity. The more well-designed a product is the better value it can deliver to the users of the product. The same thing is true of quality – by always having quality as the foremost driver of our production and applications we can be sure that we can meet the demanding expectations of our clients across industries as diverse as pharmaceuticals, automobiles, air-conditioning, electronics and water pumps and armature.

The first time we meet a prospective client or project the process is often similar regardless of the starting point – the initial need which has been identified from the client side can be either very specific, or be a diffuse desire to either decrease costs or increase say the speed of production. From this point our needs analysis begins and we start to design a leak testing solution in a collaborative discussion with our clients with multiple iterations back and forth until we have arrived at a design and build which is optimal for their particular needs.  Following this the product is produced, tested and then delivered for commissioning at the client – where necessary we do a physical handoff and training in use of the machine or application.

As leak detection is most often an additional step in the production process, which adds cost, it is imperative to work with a company that has a wide range of experience and has a willingness to work with a customer in a partnership approach to define a test method that allows for the right ratio between equipment cost and productivity.

Nolek was founded in 1973 and today is is one of the world’s leading suppliers of leak detection equipment.From the onset, Nolek has been involved in developing standards for leak testing and leak detection and has contributed to many of the industrial leak detection developments.

Nolek’s extensive experience, which includes all measurement and detection methods, has resulted in a broad knowledge and understanding of customized leak testing equipment across a wide range of industries.

In addition to building test systems, Nolek can provide customers with guidance throughout the entire process ranging from product design advice (to make it compatible with the objected leak test requirements) to assistance with maintenance, service and calibration.

Nolek has developed it’s own line of decay type instruments and related calibration tools and is able to deliver any type of test method ranging from its decay technology to  the most sensitive helium leak detection methods.

Nolek’s vision is to assist in improving its customers’ product specification(s) and production requirements. Quality is a KEY word within its company and it is a major goal of Nolek’s management to ensure that every employee constantly applies the best possible quality principles.

Nolek is ISO 9001 and ISO 14001 certified.

Nolek headquarters and manufacturing facilities are situated in the southern part of Stockholm (Sweden), while Nolek also has a large manufacturing facility in Malaysia. Other direct Nolek offices can be found in the USA, Denmark, and Hungary, while Nolek has approximately 15 distributors worldwide.

Quality and value are our primary drivers

Our vision is to assist in improving our customers’ product specification(s) and production requirements. Quality is a KEY word and it is a major goal of Nolek’s management to ensure that every employee constantly applies the best possible quality principles.

Leak detection today is used in many applications from heavy industrial requirements such as on oil platforms to the most demanding applications in the medical, science and space-related fields. Each of those areas require tailored solutions and instruments. Additionally, all applications require more and more stringent specifications and have to meet international standards.

From conventional methods to other measurement techniques

We can utilise all available technologies within leak detection and testing, as well as proof testing and have excellent know-how of all measurement methods (i.e. pressure measurement, flow measurement and gas/helium measurement). Conventional pressure and flow measurement methods are offered for most applications, but if technical conditions or stringent requirements need to be met we can use the helium method.

Our long experience and knowledge of helium leak testing is unique. Ultimately, together with our customers, we decide which method is best suited for their specific needs.


With over 40 years in existence we have always worked with quality as our guiding principle – and this is reflected in the reputation and reliability of our products and services.

We are on a mission to become the world’s leading total solution provider within leak testing. In order to reach this goal, Nolek, wants to partner with its customers to reach high set quality standards. In fact, Nolek doesn´t believe that high quality standards are enough – we think our customers deserve to have products with outstanding quality.

Our Quality² © concept with six simple steps to success

Nolek will help its customers design products that meet leak testing requirements according to pre-set standards in that specific industry.
Nolek will custom engineer or find an instrument that can test the customer’s product in the most cost efficient manner possible.
Nolek will engineer and build its machines according to ISO 9001, GXP, CE, and UL specification requirements.
Nolek will focus on quality every step of the way, from the drawing board to the finalized product.
Nolek will help the customer adapt newly developed proprietary software to monitor and control the production process in order to track yield, quality and overall efficiency.
Nolek will offer its customers different service packages, from a preventative service and corrective service, to taking the complete service responsibility 24-7.
Together, let us make Quality² ©, the new industry standard.
