Weiconlock AN 301-72 Flange Sealing Adhesive is a premium quality grade of anaerobic adhesive used for sealing larger threaded connections, flanges and pipes. This special grade is made with PTFE and exhibits outstanding chemical resistance. In addition, Weiconlock AN 301-72 Flange Sealing Adhesive is non-marking, NSF approved for food processing applications and DVGW approved for use in sealing gas installations. AN 301-72 offers high temperature resistance and is used in applications with temperatures between -60ºC and 200ºC. This high quality grade has a high viscosity for accurate applications to larger connections and cure with a medium level of strength which means that seals made with AN 301-72 may be able to be disassembled using normal tools. The Weiconlock White Line Weiconlock AN 301-72  Flange Sealing Adhesive is part of the Weicon White Line of anaerobic adhesives that have been specially developed for tightly controlled environments such as food or beverage processing or pharmaceutical handling. Other grades in this range include our AN 301-43, AN 301-70, AN 301-65, AN 301-38 and Weiconlock AN 301-48. More information on each is available on the each grades page or by contacting your local Associated Gaskets branch.

These special pen shaped bottle allow for easy, accurate application while the base minimises the chances of any spillage. Surface Preparation In most applications, Weiconlock AN 301-72 Flange Sealing Adhesive does not require pre-treatment of the surface as even slightly oily surfaces cab still be adhered. That being said, best results will be achieved on cleaned and degreased surfaces (Weicon Surface Cleaner is ideal for this task). If required the parts should be slightly roughened. Processing Weiconlock AN 301-72 is ready to use from the moment you open the bottle. It should be evenly applied direct from the bottle/tube with the dispensing tip (avoid direct contact between the dispensing tip and metal). Weiconlock AN 301-72 should be applied evenly around the thread or flange surface. Do not pour any excess Weiconlock fluid that has made contact with metal back into the bottle. Even the smallest metal particles will cause the contents of the bottle to cure once the lid is re-closed. In series construction or production line situations, the use of manual or automatic applicators is suggested. For full use instructions, please consult the TDS & SDS for this product (both of which can be provided by your local AG branch).
