About Dual Taper Technology on TOUGH LOCK Retaining Heads


Are the TOUGH LOCK™ Retaining Heads backwards compatible with older MIG Guns?

Neck Taper ComparisonTregaskiss TOUGH GUN™ Robotic Air-Cooled MIG Guns, Bernard™ Best of the Best Semi-Automatic Air-Cooled and Bernard TGX™ Series MIG Guns with the mating taper on the neck are compatible with this retaining head.

If your MIG gun is more than 5 years old, it may have the old style neck without the taper. This retaining head will not thread all the way down on this older style of neck.

Refer to the image on the right that shows both styles of necks to verify which neck you have.
 

Will TOUGH LOCK Retaining Heads with Dual Taper Technology cost more?

No. Pricing for the Dual Taper Retaining Head is exactly the same as their single taper version.
 

How can I tell the single taper retaining head from the Dual Taper design?

The Dual Taper Retaining Heads have several identifying features:

  • Black o-ring (single taper TOUGH LOCK Retaining Heads have red or green o-rings)
  • Double score mark around teh circumference of the retaining head just above the clip
  • Part number roll marking along the bottom edge of the retaining head
