Böhler Welding back cap O-ring for TIG torches with 17/18/26 consumables (BT17, BT26, ST 2200, ST 3000, ST 4000). It seals the joint between back cap and torch head so that gas does not escape at the rear. Pack of 10.
What it is for
Replace it when it is cracked, hardened or cut, because a leaking torch rear weakens the gas shield. Best practice is a new O-ring with every back cap change.
