Before You Replace a MIG Nozzle, Check These 3 Sizes
A quick visual check before you order.
Keep the old nozzle beside you. Check its part number and torch model first; then compare these three measurements on the replacement listing.
Connection fit
Start at the back. Match the mounting style and interface dimensions to your torch and diffuser. A similar-looking nozzle may attach differently.
Opening diameter
Measure the bore at the front—not the outside diameter. Compare the same dimension on the replacement listing.
Overall length
Measure from the rear mounting edge to the front lip. Then check the installed relationship between nozzle lip and contact tip.
Match the part number before the dimensions.
Size alone cannot confirm compatibility. Verify the torch model, mounting style and manufacturer reference on the product page. If the listing omits a measurement, do not guess from the photo.
