Radnor 14T45 Contact Tips

Radnor 14T45 contact tips are copper welding consumables supplied in a pack of 25. They are designed for use with Tweco-style MIG guns that accept the 14T45 series. The .045 inch bore matches wire of the same diameter for standard feed setups.

Suits MIG welders using .045 wire

These tips suit welders running .045 inch wire through a compatible Tweco-style gun. They are not for operators using different wire diameters, alternative tip series, or guns with a different thread pattern. Buyers who need a larger bore or a different mounting style should look at other series.

Series 14T45 compatibility

The decisive specification is the 14T45 series designation, which confirms fitment with Tweco-style guns built for that pattern. The pack contains 25 copper tips stamped with the Radnor brand. California Proposition 65 warnings apply to this product.

Questions about this item

What thread size does the 14T45 contact tip use to fit my Tweco gun?

The tip is a Series 14T45 made to thread into standard Tweco-style diffusers; match the gun's diffuser series to 14T45 for correct fit.

How do I install the 0.045 copper tip without cross-threading the 14T45 threads?

Start the tip by hand into the diffuser until fully seated, then snug with a tip wrench; rushing the first turns is the common error that damages threads.

When should I replace the copper contact tips in this 25-pack during MIG welding?

Replace a tip when the 0.045 bore wears oval, copper fouls heavily, or wire feeds erratically; each pack supplies 25 tips for scheduled change-outs.
