The Weld-On 5020 4" Swab Dauber is a purpose-built applicator designed to make priming and solvent-cementing pipe joints faster, cleaner, and more consistent. Sized for use on pipes with 3" to 8" diameters, this swab delivers controlled coverage inside fittings and along pipe ends where reliable bonding is required.

  • Fits standard quart cans and MT-651 empty quart cans for easy loading and refilling on the jobsite.
  • 4" swab head is sized for broad interior coverage in larger-diameter pipes.
  • Provides more controlled application and less drippage than loose brushes or rags.
  • Well-suited for plumbing, irrigation, sprinkler and general pipe-joining applications.
  • Simple to use: dip into the quart, apply evenly, and follow the adhesive manufacturer's directions for best results.
  • Inventory reference: SKU 12071 for ordering and stock checks.

For safe use, wear appropriate personal protective equipment and follow the safety and application instructions provided by the adhesive or primer manufacturer. Store the dauber upright or capped between uses and keep replacement swabs on hand to maintain productivity on larger jobs. The Weld-On 5020 Swab Dauber helps reduce mess, saves time during repetitive joints, and offers a convenient way to apply primers and solvent cements accurately across a range of pipe diameters.
