  • Industrial Quality Threadlocker with DVGW Approval for Locking and Sealing Gas Lines and Fittings. 
  • High Strength Adhesive used to create permanently locked fittings that will be hard to disassemble. 
  • Medium Viscosity. 

Weiconlock AN 302-70 High Strength Thread Locking Adhesive is a industrial grade threadlocker manufactured by Weicon in Germany. This grade is designed for permanently locking and sealing threaded bolts, fittings and stud bolts. It is used on fittings up to M 20 (R ¾") in diameter. 

AN 302-70 has been tested and approved by DVGW. This allows it to be used for locking, bonding and sealing threaded fittings on gas equipment and gas lines.  

This high quality threadlocker is green in colour. It will achieve handling strength 10 to 20 minutes after application and be fully cured in about 3 to 6 hours. Once cured, it can withstand temperatures between -60°C and +150°C. 

Like all of our Weiconlock range, this is an anerobic adhesive. It will only activate and begin to cure when in contact with metal and deprived of air (e.g. when sandwhiched between a bolt and a nut). Consequently, Weiconlock AN 302-70 has no pot life. 

For more technical information on this quality threadlocker, please consult our AN 302-70 Technical Data Sheet. The video below also provides a brief demonstration of how it can be applied and some of its main features.
