Repair Packers, Test Plugs and Accessories: Quality Solutions "Made in Germany" from HD Sanierungstechnik
With well-engineered products für short liner rehabilitation, leak testing and pipe isolation, HD Sanierungstechnik offers a perfectly coordinated system for trenchless sewer rehabilitation. These high-quality "Made in Germany" solutions are also available from MOWOTAS Kanaltechnik and support rehabilitation contractors in meeting the daily challenges of on-site operations.
Repair Packers for Maximum Flexibility
One of the key advantages of HD repais packers is their exceptionally wide application range. Thanks to their multi-size design, a single packer can cover multiple pipe diameters. This reduces the amount of equipment required while increasing flexibility on site.
The packers offer:
Wide diameter coverage
Compact initial diameters
High dimensional stability combined with excellent flexibility
Outstanding pushing and manoeuvring characteristics
Customisation options for specific applications
Particularly for the rehabilitation of lateral connections from DN 100 to DN 150, HD offers well-designed solutions for professional short liner rehabilitation. In addition to repair packers for straight pipes, HD also manufactures specialised bendy packers for lateral pipes with tight bends and mulitple changes of direction.
HD Pipe Plugs and Test Plugs for Sewer and Pipeline Applications
The range is completed by high-quality pipe plugs and test plugs for a wide variety of applications in sewer and pipeline maintenance. Whether used for temporary pipe isolation during maintenance, repair and rehabilitation works or for carrying out leak tests, HD Sanierungstechnik products provide a reliable solution for everyday site use.
A key advantage is the perfectly coordinated system of pipe stoppers and test plugs. Designed to work seamlessly together, these components enable efficient joint testing and pipeline testing, even in branched drainage networks featuring multiple diameter changes. This simplifies testing procedures, speeds up inspections and increases efficiency on site.
Navigation Balls and Flexible Air Push Rods Make Installation Easier
Offset joints, pipe edges and minor pipe deformations often make accurate positioning of repair packers more difficult. The HD Navigation Ball, which can easily be screwed onto the front of the packer, helps operators negotiate such obstacles much more effectively. This saves time and reduces the need for time-consuming repositioning on site.
For more distant repair locations or pipe runs with multiple bends, HD also offers highly flexible air push rods. These follow the pipe route considerably more easily than conventional systems and allow precise positioning of the repair packer even in difficult-to-access areas. The Supraflex pushing aids have proven particularly effective in complex lateral connection applications.
Practical Accessories for Professional Short Liner Rehabilitation
The HD product range is completed by a variety of practical accessories designed for everyday site work. These include portable pressure control units with two or three pressure circuits, access packers, wheel sets and centring brushes for repair packers, as well as turning and locking pliers for push rods. All components are designed to work together seamlessly and support efficient workflows in trenchless sewer and pipeline rehabilitation.

HD Lateral Packer DN 25-1000 mm
Multidimensional Lateral Packer for Straight PipesThis multidimensional, lateral rehabilitation packer has been specially developed for professional pipe rehabilitation and offers outstanding flexibility and durability. Thanks to its unique design, it is ideally suited for straight pipes as well as bends of up to 45°. With a wide range of applications from DN 25 to DN 1000 and lengths of up to 5000 mm, this packer offers maximum versatility in daily use. The innovative material construction allows for exceptionally large expansion, meaning that multiple pipe dimensions can be covered with just one packer. For example, an HD packer in size DN 125–300 covers up to five different pipe diameters – a clear advantage in terms of efficiency and cost-effectiveness. Maximum Adaptability and Ease of Use The small initial diameter allows for use even in confined spaces. At the same time, the combination of high flexibility and dimensional stability ensures optimal adaptation to different pipe diameters and guarantees a reliable, complete seal.The excellent sliding behaviour enables precise positioning – even in hard-to-reach areas. For additional flexibility, the packer can be fitted with an optional flex adapter for air-powered push rods. Efficient Pipe Rehabilitation Using the Short-Liner-MethodThe packer is fitted with a short liner, guided to the rehabilitation site within the pipe using air-powered push rods, and inflated using compressed air. After a curing period, the packer is deflated and removed. After each use, the packer should be carefully cleaned and inspected for damage.Your benefits at a glance Covers a wide range of sizes with just a few packers Suitable for DN 25 to DN 1000 Can navigate bends up to 45° Extremely robust and durable design High flexibility combined with a stable shape Simple and precise positioning Ideal for confined spaces For all pipe materials (KG, SML, Stoneware) Can be upgraded for steam curing Cost-effective and efficient in use Just three HD packers are sufficient to fully cover nominal diameters from DN 30 to DN 1000. Note: For pipe bends from 45° to 180°, we recommend the appropriate HD bendy packer from the same series.Please refer to the downloads provided for technical details.
HD Test Plug, Ideal for Changes in Pipe Diameter, DN 25 -500, Made in Germany
The HD test plug enables precise and reliable leakage testing of newly installed, rehabilitated and existing pipelines in accordance with EN 1610. Specially developed for use in complex drainage systems, the test plugs provide reliable testing of individual pipe sections and joints, even in challenging pipe networks. Thanks to its patented design, each test plug covers a wide range of nominal sizes. This means that several different pipe diameters can be tested with a single test plug, making it ideal for pipe systems with changes in diameter. Its small deflated diameter and high flexibility through bends, combined with suitable flex adapters and flexible push rods, enable the test plug to pass through pipe bends of up to 90° and reach test locations further along the pipe system. For safe and efficient leakage testing, we recommend using the test plug in combination with the corresponding HD pipe stopper. The test plug and pipe stopper are designed to work together, operate at the same pressure and can be used together in a single operation. This reduces both the workload and the time required to set up the test. HD test plugs are “Made in Germany” and incorporate proven HD packer technology. Their robust construction ensures reliable operation and a long service life. Overview and benefits: For leakage testing in accordance with EN 1610 Ideal for changes in pipe diameter and complex pipe systems Operates at the same pressure as the HD pipe stopper Test plug and pipe stopper can be used together in a single operation Made in Germany Available sizes:Nominal sizes: DN 25–500
Turning and Locking Pliers for Packer Push Rods
The turning and locking pliers securely grip the push rod, allowing repair packers to be manoeuvred, rotated and accurately aligned. This makes it considerably easier to position the packer precisely inside the pipe during patch repair installation. The pliers are suitable for all commonly used packer push rods and can be attached at any point along the push rod. Overview and benefits: Securely grip and hold packer push rods Allow packers to be rotated and accurately aligned Make it easier to manoeuvre and position the packer inside the pipe Suitable for all commonly used packer push rods
Flexible HD Air Push Rod with Hexagonal Coupling, Made in Germany, 0.5–4 m
The HD air push rod with hexagonal coupling makes it easy to push and position packers safely inside the pipe. It can also be used to rotate and accurately align the packer when required. The hexagonal coupling reliably transmits rotational movement to the packer, enabling precise positioning at the repair site. The air push rod is made in Germany and manufactured to a high standard. Its flexible design makes it easier to guide the packer through bends and changes in direction. The integrated hexagonal safety coupling provides a quick and secure connection to the compressed-air supply. The air push rod is available in lengths ranging from 0.5 to 4 m. Overview and benefits: Hexagonal coupling for controlled rotation and precise positioning of the packer Flexible design: suitable for bends and changes in direction Hexagonal safety coupling Made in Germany Available lengths: 0.5–4 m
