The new MAPAL sealing rings for flanges and adapter ©MAPAL
MAPAL prioritizes the creation of eco-friendly tools, a commitment that extends to its accessories and additional products. Traditionally crafted from brass, the sealing rings used for flanges and adapters are noted for their robust resistance to mechanical wear and superior corrosion resistance. These rings are employed to manually seal the clamping bore on HSK spindles and adapters, safeguarding them from contamination. However, standard brass sealing rings, along with their corresponding holding screws, contain trace amounts of lead. The dispersion of lead poses a risk to the environment, prompting numerous countries to enact stringent regulations to curtail environmental lead exposure.
Environmentally friendly alternative
In response to the REACH regulation – the European Chemicals Regulation for the Registration, Evaluation, Authorisation and Restriction of Chemicals, which regulates the use of lead and imposes an obligation to inform users, MAPAL decided to go a step beyond the legal requirements. The company subjected its products to a critical review and looked for alternative solutions. In the meantime, new production of sealing rings and holding screws has been switched to environmentally friendly materials.
Product improved – performance increased
During the material changeover, MAPAL also focussed on technical product improvements. Thanks to these, the maximum speed of the sealing rings could be increased by up to 100 per cent. An additional anodised layer applied to the rings, visible through the blue colour, effectively protects them against corrosion. The fatigue strength of the sealing rings is also guaranteed in the new version and remains at the usual high level. The interchangeability of the rings is ensured.
