Spears 829-585FE 8X6 PVC Eccentric Reducing Coupling, Schedule 80 Socket

The Spears 829-585FE is an 8X6 PVC Eccentric Reducing Coupling built for Schedule 80 socket (SOC) connections, transitioning an 8" pipe run down to a 6" line in a single fitting. Molded from durable PVC, this reducing coupling delivers the corrosion resistance and mechanical strength required for demanding piping and conduit systems. Its Schedule 80 wall thickness provides added pressure capability and structural durability compared to lighter-duty Schedule 40 fittings, making the 829-585FE well suited to industrial and commercial installations where a reliable size transition is required.

Key Features

  • Trade Size: 8X6 (8" x 6") reducing configuration allows a clean transition between two pipe sizes using a single fitting.
  • Durable Construction: Molded PVC material resists corrosion and chemical attack for long-term service life in piping and conduit runs.
  • Eccentric Reducing Design: The eccentric (ECC) offset keeps one side of the pipe wall aligned, helping maintain a consistent flow line or grade through the transition rather than a centered reduction.
  • Socket (SOC) Connection: Solvent-weld socket ends on both sides provide a secure, permanent joint when properly cemented.
  • Schedule 80 Rating: Heavier wall thickness than Schedule 40 PVC fittings supports higher pressure ratings and greater mechanical strength for demanding applications.

Technical Specifications

  • Product Size: 8X6
  • Material: PVC
  • Schedule: Schedule 80
  • Connection: Socket (SOC)
  • Configuration: Eccentric Reducing (ECC RD)

Typical Applications

  • Industrial and Commercial Piping Systems
  • Pipe Size Transitions in Pressure Piping Runs
  • Conduit and Raceway Size Reductions
  • Process Piping Requiring Schedule 80 Durability
  • Renovation and New Construction Projects

Why Spears?

Spears PVC fittings are molded to consistent tolerances for reliable solvent-weld joints, and the Schedule 80 construction of the 829-585FE reflects a build quality suited to professional, code-compliant piping and conduit installations. Choosing a purpose-built eccentric reducing coupling like this one helps installers maintain proper flow alignment while stepping down pipe size, without sacrificing the durability that Schedule 80 PVC is known for.

Spears 829-585FE – Frequently Asked Questions

1) What size reductions does the Spears 829 Schedule 80 eccentric reducing coupling come in?
Two size transitions: 8 x 6 inch (part 829-585FE) and 10 x 8 inch (part 829-628FE). Both are PVC Schedule 80 with solvent-weld socket ends on each side, so each drops a run down one nominal pipe size in a single fitting.
2) Why use an eccentric reducing coupling instead of a concentric reducer on a PVC line?
The eccentric offset keeps one side of the pipe wall aligned through the transition, so the flow line or grade stays consistent. On a gravity or drainage-style run, or anywhere you need the invert or the top of pipe to stay flush, that is what you want. A concentric reducer centers both sizes on a common axis and steps the wall in evenly all around, which is fine for pressurized runs where alignment of the bottom of the pipe does not matter.
3) Do I need to thread this coupling or glue it?
It is solvent weld only. Both ends are socket (SOC), so the pipe slips into the socket and is joined with PVC primer and cement to make a permanent joint. There is no thread on either end, so if your existing line terminates in male NPT you need a threaded adapter or transition fitting ahead of it.
4) Will a Schedule 80 coupling fit Schedule 40 PVC pipe?
Yes on the outside diameter. Schedule 40 and Schedule 80 PVC share the same nominal OD at a given trade size, so 8 inch Sch 40 pipe solvent welds into the 8 inch socket of the 829-585FE. The difference is wall thickness: Sch 80 has a heavier wall than Sch 40, which is what gives it the higher pressure rating and mechanical strength. Keep in mind the system pressure rating is set by the weakest component, so mixing Sch 40 pipe into a Sch 80 fitting drops you to the Sch 40 limit.
5) Can I use this PVC reducing coupling for electrical conduit size reductions?
Yes, size reductions in conduit and raceway runs are one of the stated applications for this Spears Sch 80 eccentric reducer, alongside industrial and commercial pressure piping and process piping. It is a solvent-weld PVC fitting either way, so the joining method is the same whether the run is carrying fluid or cable.
6) Which part number do I order for a 10 inch to 8 inch Schedule 80 PVC transition?
Spears 829-628FE. That is the 10 x 8 inch eccentric reducing coupling, Schedule 80 PVC with socket ends both sides. The 8 x 6 inch version is 829-585FE.
7) What material is the Spears 829 eccentric reducer made from, and will it hold up to chemicals?
Molded PVC. It resists corrosion and chemical attack, which is why it gets specified on process piping and industrial runs rather than metal fittings that would corrode. For hot lines or aggressive service beyond PVC's range, a CPVC fitting is the usual step up.
