Pipe connectors

About the system

KLEMP pipe couplings are innovative and versatile products for the construction of safe balustrades, handrails, barriers and much more, both in industry and in the private sector. KLEMP couplings allow easy and very fast connection of standard pipes for the construction of modular steel and aluminum structures.
KLEMP couplings are elements that allow extremely flexible implementation of solutions. Despite their simplicity, they are very effective and have proven themselves over the years in thousands of projects all over the world. The KLEMP system safely combines standard sizes of steel and aluminum pipes in almost any layout imaginable, using the widest range of pipe couplings available on the market today.
The couplings are made of hot-dipped galvanized cast iron, giving them high corrosion resistance and long service life.

Why KEMP couplings?

Steel and aluminum pipes have been used as a construction element for many years. They are durable, have no sharp edges and are readily available anywhere in the world. The problem with using steel and aluminum tubing to build various structures is the issue of connections. Threaded pipe must be delivered to the job site in a precisely defined size and offers virtually no flexibility in installation. Welding requires skilled personnel, is a complicated and time-consuming process, and requires specialized equipment.

z systemem KLEMP
Our product for the construction of all types of steel and aluminum pipe structures meets this challenge. Klemp pipe connection system.
Our product range includes different types of galvanized, black and natural connectors.
They are easy to design, easy to install and cost effective due to their modularity and simplicity. The design rules are simple and very effective.



From simple protection of platforms or walkways in workplaces to safe railings in the harsh environment of harbor quays, bridges or canals. The KLEMP pipe connection system offers complete solutions that allow you to carry out such projects.

Central to the design principles of the KLEMP system is the principle of realizing a quick and easy connection of pipes. Our connectors provide the versatility to build any design. The KLEMP system consists of cast iron, galvanized connectors. We have developed a wide range of connectors in six different sizes. The hexagon socket clamping screw provides a secure and tight connection to the pipe. Stainless steel screws are available upon request.


KLEMP pipe couplings are easy to assemble and disassemble with an Allen wrench, reusable.

The pipe couplings are fixed with a hexagon socket screw. In this way, any desired design can be perfectly realized, whether it is complex or rather simple - the possibilities are almost unlimited, as the choice of different types of pipe connections means that almost anything is possible, whether you are working with aluminum or galvanized steel pipes, as long as the correct diameter is maintained.

Thanks to the simple design, our connectors allow for very quick assembly, which significantly reduces labor costs.

Choice of connectors

The connectors shown in the photos are described with dimensions. Each connector has a simple and unique reference code called type to distinguish it from all other connectors. The full code consists of the connector type and size, which indicates the size of the matching pipe or pipes that can be connected.
In our offer you will find connectors for round and square pipes
In our offer you will find square connectors with diameters of 25 mm and 40 mm
In our offer you can find black galvanized connectors and natural connectors without coating.


In our offer you will find round connectors with diameters of 21.3 mm, 26.9 mm, 33.7 mm, 42.4 mm, 48.3 mm, 60.3 mm

* The actual dimension of a connector The clamping screw fixes the pipe with the smaller diameter (tolerance approx. 1.5 mm)
Some KLEMP connectors are approved by TÜV, a leading European and independent testing institute.
We give general guidelines for the use of pipe fittings. However, due to the nature of the product, the ultimate responsibility for the selection and proper use of connectors rests with the customer. The customer should also make sure that the existing structures to which the Klemp couplings will be attached have sufficient load-bearing capacity to support both the Klemp elements and the potential load, taking into account wind forces, snow loads and other superimposed forces.

    How are the tubes sized up? (outer diameter)

    Each tube description provides outer tube diameter. In addition, another value provided for a given dimension (e.g. 42x2, 42x3) determines the thickness of the outer wall of the tube. The tube diameter reflects the outer diameter. The associated tubefittings have the same tube diameter in the product name, therefore you always know whether you have the correct size of a connector for your tube. The inner diameter of the fittings is slightly bigger, so you can easily slide them over the tubes.

    Why does the cost of delivery increase when longer product lengths are selected?

    Shipment of oversized loads, i.e. exceeding 120-140 cm, is associated with high transport costs that we incur on the delivery of our products. We sell goods to all EU countries, which in the case of such loads is often associated with a large distance and a non-standard size of the packaging. Weight is another criterion important especially in the case of the purchase of heavier tubes (steel). However, the most important factor affecting the cost of shipping in this case is the length of the load.

    Is it possible to order the tubes in customized dimensions with accuracy to mm?

    No. Due to the already assumed tolerance for cutting (2-3 mm), the adopted length possible to order was rounded to full cm

    To what depth do the tubes go into tubefittings?

    The very depth to which a tube goes in the connector depends on the tube connector used and its diameter.

    The tube usually goes inside the fitting at the depth of at least 2 to 3 cm.

    Usable dimensions can be found in the technical illustration of each tube connector.

    Are the tube diameters provided the inner or outer dimensions?

    The diameter of the tube provided first indicates the outer dimension, followed by the sign "x" after which stands the thickness of the tube wall.

    What is the weight of the tubes?
    The weight of 1 rm of the tube is given for each tube in the Product Specification section.

    Steel tubes are galvanized - what does it mean?

    Our steel tubes are hot-dip galvanized. This means that the steel tubes are coated with a layer of zinc, which makes them resistant to corrosion. The tubefittings are made of cast iron and are fully galvanized. As a result, they are also suitable for external use.

    What is the difference between a steel and aluminum tube?

    Tubes made of steel are stronger and stiffer. For this reason, steel tubes are often used for structures that are exposed to heavy loads and characterized by larger spans. Due to their industrial nature and resistance to scratches, steel tubes are also often used in the manufacture of furniture. Their disadvantage as compared to aluminum tubes is that steel is much heavier. Aluminium tubes are often used for advertising structures. This is to avoid adding up unnecessary load.

    What is the strength of an aluminum tube and a steel tube?

    An aluminum tube, compared to a steel tube, is more susceptible to bending over long intervals. According to our calculations, the maximum distance between two supports (for a wall frame) or two supports (for a freestanding frame) is 150 cm. It is worth noting that steel is much heavier than aluminum. The actual weight per meter can be found in the product description. If you need additional strength calculations, we recommend consulting a constructional engineer or scaffolding specialist.

    Can the tubes be used outdoors?

    All tubes are suitable for external and internal use.

    Galvanized tubes were covered with a protective layer against atmospheric factors using hot-dip galvanizing.

    Aluminium tubes (black) are naturally suitable for external use as they get covered with a protective layer as soon as they come into contact with oxygen.

    Black steel tubes are protected from the weather conditions by a black UV-resistant coating.

    In the course of time corrosion may occur in damaged places and at the edges of the cuts.

    Rust does not affect the strength of the structure and can usually be removed.

    What are the longest tubes I can order with you?

    For galvanized steel tubes and raw aluminum tubes, the maximum length is 600 cm. Black tubes - 300 cm.

    You can order the tubes in maximum length of 300 cm through the shopping cart at our store. If you need longer tubes, please contact us by e-mail.

    Do you cut the tubes to the desired length?

    We cut the tubes to the desired length. Tubes can be cut starting at a length of 5 cm. We do not charge any costs for cutting the tubes. You can select the desired length on the product page and the price will instantly show up.

    What tube diameter do I need?

    The diameter of the tube you need depends on the structure, the span and the weight that the structure is to support. Tables are often made of tubes with a diameter of 42.4 mm. Coat hangers, stair railings, clothes hangers and cabinets have diameters of 26.9 mm and 33.7 mm. For large projects such as canopies and pergolas, diameters of 42.4 mm or 48.3 mm are often used. Click here for a full overview.

    How quickly does the tube get damaged?

    Our tubes are stable and made of durable material. Thanks to their high quality, our tubes are resistant to damage. However, minor scratches may appear on the external surface of the tubes.

    Galvanized steel tubes are resistant to scratches and impacts, and thanks to their sturdy look, any possible scratches will not be noticeable. Aluminum is prone to scratches and can be more easily damaged due to the softness of the material. The black tubes are covered with an impact-resistant coating. Despite the coating, we recommend careful handling of the tubes as the coating is sensitive to scratches, especially with sharp objects.
