OVERVIEW

Keep Your Wire Running Smoothly with Parker

Every welder knows the frustration of a bad liner. You're in the middle of a bead, and suddenly the wire stutters, the arc sputters, and you're left with a mess to grind out. Often, the culprit is a dirty, kinked, or worn-out liner. The Parker B43115X is the reliable fix you need to get your Bernard-style MIG gun back in top fighting shape. Designed to replace the standard Bernard 43115 liner, this 15-foot conduit is built to handle the daily grind of the shop floor, ensuring your wire gets from the feeder to the puddle without a hitch.

This liner is sized perfectly for the most common wire sizes used in the industry: .035" and .045". Whether you are running solid mild steel wire or flux-cored wire, the Parker B43115X provides a smooth path that reduces drag. Less drag means less strain on your drive rolls and feed motor, and most importantly, a consistent arc that lets you focus on your technique rather than fighting your equipment. It fits perfectly into 15-foot Bernard Q-Guns, S-Guns, and T-Guns, making it a versatile addition to your tool crib.

Don't wait until your gun is completely jammed to think about maintenance. Swapping out your liner is one of the cheapest and most effective ways to improve your weld quality instantly. Parker Torchology has built a reputation for making aftermarket parts that work just as hard as you do. The B43115X is tough, flexible, and ready to work. If you are experiencing erratic feeding, bird-nesting at the drive rolls, or surging wire, it's time to pull the old liner and slide in a fresh Parker B43115X. It’s the smart, budget-friendly choice for professional welders who demand performance.

Why Choose the Parker B43115X?

  • Perfect Fit: Slides right into your existing Bernard 15ft guns.
  • Smooth Feeding: Reduces friction for a stable, consistent arc.
  • Durable: Made from quality spring steel to resist kinking.
