Loctite 55 honored with two Red Dot Awards 2025

Loctite 55 pipe sealant has been honored with two Red Dot Awards 2025 in the categories of ‘Product Design’ and ‘Sustainable Design’. Henkel received this prestigious recognition for the robust and convenient design as well as for the sustainability improvements of the packaging of the 160m pack for its leading thread sealant cord. Loctite 55 has already been granted with the German Packaging Award 2024 followed by the WorldStar Global Packaging Award earlier this year. 

For the Red Dot Design Award for Product Design the jury particularly pointed out the ‘robust design and well-thought-out production from a mono-material both contribute to the sustainability of Loctite 55’. For the Red Dot Design Award for Sustainable Design, a new meta-category granted in 2025 for the first time, the jury praised that ‘the Loctite 55 applicator boasts an ergonomic design with a number of user-friendly and environmentally conscious features.’

“Winning two Red Dot Awards is a powerful validation of the deep expertise and entrepreneurial spirit that drives our innovation culture at Henkel,” said Niamh O’Reilly, Vice President Innovation for General Manufacturing and Maintenance at Henkel Adhesive Technologies. “This achievement reflects the outstanding collaboration across our specialist teams, who worked closely to understand and anticipate customer needs, translating insights into a solution that sets a new benchmark in both usability and sustainability. The jury’s recognition of Loctite 55’s enhanced handling and its sustainability improvements – such as reduced waste and improved recyclability – underscores our commitment to advancing the circular economy. We are especially grateful to our strategic design partner, Dolmen, whose creativity and partnership were instrumental in bringing this customer-centric innovation to life.”

Loctite 55 is used by numerous professional fitters and plumbers to seal pipe threads and fittings made of metal and plastic. It is suitable for sealing hot and cold water, natural gas, hydrogen gas and other common media found in traditional plumbing systems.  In 2024, Henkel launched a new 160m package that has been developed and improved based on an extensive customer survey. The new packaging design combines improved functionality for the easier, quicker, and more ergonomic application of the thread sealant cord, and advanced sustainability by using mono-material made of 70 percent post-consumer recycled plastic.

An ideal choice for sealing metal and plastic threaded joints, Loctite 55 replaces hemp, paste, and PTFE tapes and proves to be an essential item for any toolbox. The product requires no curing time and results in an immediate, full pressure seal. Simply wind the proper amount onto the thread with tension and then cut the thread sealant with the integrated cutter. Unlike PTFE tape, Loctite 55 can be reliably readjusted to align fittings and measuring devices without the risk of tearing and causing leaks. This gives users more flexibility during installation and saves time for cleaning and resealing.

The Red Dot Design Award is one of the world’s most respected design competitions, recognizing excellence in product design since 1955. Winning a Red Dot signals innovation, high quality, and outstanding design. Judged by an international expert jury, winners gain global recognition and the right to use the prestigious Red Dot label. The official award ceremony took place on July 8 at the Red Dot Museum in Essen, Germany.
