A versatile, easy to use anaerobic adhesive containing PTFE. This grade of Weiconlock has been specifically designed for maximum versatility and can be used as either a liquid gasket for metallic flanges or for the permanent locking and sealing of threaded pipes or cylindrical assemblies.
When used to create a seal on these types of assemblies, Weiconlock AN 305-72 Flange Sealing Adhesive provides an immediate sealing effect that only strengthens once the adhesive is fully cured (which will occur in around 5-10 hours depending on the conditions). Seals created with AN 305-72 will exhibit medium strength and will be able to be disassembled (when required) with normal tools.
Further enhancing its versatility, Weiconlock AN 305-72 Flange Sealing Adhesive also carries DVGW and AGA (Australian Gas Association) approval for sealing gas lines and equipment.

Available Sizes
Weiconlock AN 305-72 Flange Sealing Adhesive is available from your local Associated Gaskets branch in 50ml or 200ml bottles. These special pen shaped bottle allow for easy, accurate application while the base minimises the chances of any spillage. AN 305-72 is now also available in 300ml SEMCO cartridges.
Surface Preparation
In most applications, Weiconlock AN 305-72 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 305-72 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 305-72 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).
