Vented Caps

Scope of application

Our unique FLUXX® Vented Caps are equipped with the SAVE System and are available for common thread sizes with DIN 45, 51 and 61. For the venting system we are using high-quality membranes, which enable a continuous pressure compensation with gaseous liquids, to prevent containers from swelling and collapsing. The membranes are hydrophobic as well as oleophobic, and as a result, they are not moistened even by liquids with a low surface tension.

  • Reliable protection against leaks
  • Drip-off edge for a rapid re-ventilation after contact with liquids
  • Ready to use – venting component combined with the cap
  • Declaration of food conformity

SAVE Venting System

The SAVE (SAfety VEnt) has a wedge-like design and the membrane is welded on at a 60° angle. This enables the liquids to drain off immediately, leaving the membrane unobstructed and air permeable. In addition, no splash protection is needed as the liquid flows past the beveled membrane, should a canister fall over, rather than hitting it head-on.

Suitability for hazardous goods

Because of the construction and performance values, our FLUXX® Vented Caps can fulfil all requirements for authorization with various containers in accordance with the test specifications set forth in the ADR and BAM regulations. As a standard feature, the caps are equipped with a molded on tamper-evidence ring as well as an EPE sealing ring.

Declaration of food conformity

All raw materials and additives used during the production process are fit for human consumption under the food law as well as from a physiological point of view and comply with regulations EU no. 10/2011 and EC no. 1935/2004 as well as the Foodstuffs and Animal Feed Code.

Chemical resistance

Our products achieve a high chemical resistance to many liquids. However, we cannot guarantee comprehensive chemical resistance of specific applications. Therefore, we recommend individual testing of customer applications prior to use – with the support of our experts.
