501 Style Gas Diffuser

Swapped out the old diffuser on my Pro Pulse 300 and the gas flow feels much more even at the weld puddle. The threads seated cleanly on the gun neck, no wobble or cross-threading hassle. Exactly what I needed for a solid replacement part.

The threads on this diffuser matched up perfectly with my Pro Pulse 300 gun, no wobble at all. Shielding gas flow feels steady at the weld puddle, and it's held up through a full day of heavy use.

My gas flow is much more consistent since swapping to this diffuser. It threaded onto the gun neck perfectly with no wobble, which was my main worry.
