Reliable 3 in. PVC slip coupling designed to join two nominal 3" PVC pipes with solvent-weld (glue) slip connections. Compact and lightweight, this coupling provides a clean, continuous bore for irrigation, drainage, and general plumbing runs. Part number 429-030 (SKU: 429030) is a straightforward choice when you need a durable, no-thread connection between matching 3" PVC pipe sections.

  • Material: PVC construction for corrosion resistance and long service life; suitable for outdoor irrigation and non-corrosive plumbing applications.
  • Connection type: Slip x Slip design made for solvent-weld installation—apply primer and PVC cement for a permanent joint.
  • Nominal size: Fits nominal 3" PVC pipe (measure pipe OD if uncertain before ordering).
  • Use cases: Ideal for irrigation lines, landscape drainage, gutter/drain transitions, and general non-pressurized plumbing systems.
  • Easy installation: Low-profile socket ends allow quick alignment and a smooth internal flow path when glued in place.

Before installing, confirm the pipe’s nominal size and consult local plumbing codes for suitability in pressure or potable-water systems. Keep solvent and primer out of reach of children and follow the cement manufacturer’s cure times for a secure bond.
