Item Details

  • RADNOR™ 1.25" Brass Gas Diffuser is suitable to use with 14 Series tips on up to 450 A Tweco® No. 3, Tweco® No. 4 and RADNOR™ MIG guns. Diffuser is designed in a way so it can be used with slip-on nozzle assemblies and made from 360-brass alloy bar stock that assures consistent dimensional stability. Light to medium duty welding applications can make use of this diffuser, which is sold as 5 per pack.


  • Easy identification - part no rolled stamped on the outside surface
  • Machined from 360 brass alloy bar stock to ensure consistent dimensional stability
  • Contains a conduit set screw used to hold the conduit liner in place
  • Recessed tips are generally used for higher heat applications where longer electrical stick-out is required, or in cases where the nozzle may touch the work piece (tack, spot, and stitch)
  • Flush Tips are generally used where a shorter electrical stick-out is used sometimes resulting in shorter/tighter arc lengths, this brings the tip closer to the work piece
  • Protruding Tips are generally used when welding open root pipe or any joint that requires the welder to get into a tight weld joint
  • However the down side to this is the chance of arcing the tip to the work piece, which could damage front end parts resulting in downtime needed to replace


  • Used in medium to heavy duty welding application up to 450 Amp
  • Use with 24A series nozzles only
  • Use with 34A nozzle insulator
