What wire size and gun model is the MK Products Barrel Liner Green .030 - 1/16 Wire 5PC PKG - 931-0135 compatible with?

The MK Products Barrel Liner Green .030 - 1/16 Wire 5PC PKG - 931-0135 is sized for .030 in wire. Liner bore must match wire diameter — an oversized liner causes wire wander, an undersized liner causes excessive friction. Replace liners when feeding becomes inconsistent, or every 3–6 months in production use. Always cut to the exact length specified for your MK gun model.

When should I replace the MK Products Barrel Liner Green .030 - 1/16 Wire 5PC PKG - 931-0135?

Replace MK Products contact tips, nozzles, and liners based on condition rather than calendar schedule in low-volume shops: contact tips when bore is visibly worn oval or arc becomes unstable; nozzles when spatter buildup restricts gas flow; liners when wire feeding is inconsistent after drive roll and tension adjustments. In production environments, schedule consumable replacement at regular intervals (e.g., every 4–8 arc-hours for tips, monthly for liners).

Is the MK Products Barrel Liner Green .030 - 1/16 Wire 5PC PKG - 931-0135 an OEM MK Products part?

MK Products parts are genuine OEM components for MK welding guns. OEM parts are made to the same tolerances as the original components that shipped with the gun. Aftermarket substitutes may fit physically but can vary in bore diameter, thread pitch, and conductivity — resulting in reduced tip life, arc instability, or accelerated wear of adjacent gun components.

What warranty does the MK Products Barrel Liner Green .030 - 1/16 Wire 5PC PKG - 931-0135 carry?

MK Products gun consumables carry a limited warranty against manufacturing defects. Contact WeldingMart.com with your order information and a description of the defect for a warranty assessment.
