Spears PVC DWV Reducing Flush Bushing, Spigot x Hub

The Spears PVC DWV Reducing Flush Bushing, Spigot x Hub is a drain-waste-vent (DWV) reducing fitting engineered to transition between two pipe sizes within a single, low-profile fitting. Molded from durable PVC for long-term corrosion resistance in drainage systems, this flush bushing is offered across a full family of reducing configurations, from 2" x 1-1/2" up to 8" x 6", covering eight total size combinations. The Spigot x Hub connection creates a compact, flush-fitting joint that inserts into a hub fitting on one end while accepting the smaller pipe on the other, making it a standard choice for residential and commercial waste and vent piping systems where a compact, code-compliant size transition is required.

Key Features

  • Reducing Size Range: Available in eight configurations spanning 2" x 1-1/2" through 8" x 6", including 3" x 1-1/2", 3" x 2", 4" x 2", 4" x 3", 6" x 4", and 8" x 4", to match a wide range of drain-line size transitions.
  • Durable PVC Construction: Molded from PVC for corrosion resistance and long service life in drain-waste-vent applications.
  • Spigot x Hub Connection: The spigot end inserts into a hub fitting while the hub end accepts the smaller pipe, creating a flush, low-profile joint.
  • DWV Application: Purpose-built for drain-waste-vent piping systems, not intended for pressure-rated water supply lines.
  • Flush, Low-Profile Design: Reduces bulk within tight drain-line assemblies compared to standard reducing couplings.
  • Job-Site Ready Packaging: Supplied in carton quantities for efficient stocking and job-site distribution across the available sizes.

Spears P107-251 – Frequently Asked Questions

1) What size reductions does the Spears PVC DWV flush bushing come in?
Eight reducing combinations are made: 2 x 1-1/2, 3 x 1-1/2, 3 x 2, 4 x 2, 4 x 3, 6 x 4 and 8 x 6 inch, plus an 8 x 4 for a two-size jump on large waste stacks. The first number is the spigot end that goes into the larger fitting, the second is the hub that takes the smaller pipe. Part numbers run P107-251 through P107-585.
2) How does a spigot x hub flush bushing install compared to a reducing coupling?
The spigot end is sized like pipe, so it solvent welds down into the socket of an existing DWV hub fitting (a tee, wye or coupling), and the smaller line drops into the hub on the other end. That keeps the transition inside the fitting you already have instead of adding a separate coupling and a stub of pipe, which is what you want in a tight joist bay or a packed wall. A reducing coupling is the choice when you are joining two lengths of pipe in a run and there is no hub to bush into.
3) Will this Spears bushing work with ABS drain pipe?
It is molded PVC, so it is made for solvent welding to PVC DWV pipe and fittings. ABS is a different resin and does not take the same cement joint. If the existing stack is black ABS, use an ABS bushing or a mechanical transition coupling rather than this fitting.
4) I need to drop an 8 inch building drain straight to 4 inch. Is there a single bushing for that?
Yes, the P107-582 does 8 x 4 in one fitting, so you do not have to stack an 8 x 6 and a 6 x 4. The 8 x 6 (P107-585) and 6 x 4 (P107-532) are there if you want the reduction staged instead. Keep in mind drainage code generally does not allow reducing in the direction of flow, so confirm the transition is going the right way for your layout.
5) What do I order to bush a 3 inch closet bend down to a 2 inch waste arm?
P107-338, the 3 x 2 flush bushing. The 3 inch spigot cements into the 3 inch hub on the bend and the 2 inch branch line lands in the hub end. If the branch is 1-1/2 inch instead, P107-337 takes 3 down to 1-1/2 in one step.
6) Is a flush bushing the right fitting for a lavatory trap arm tie-in at 2 inch?
For a 2 inch hub dropping to a 1-1/2 inch trap arm, P107-251 is the part. It sits flush inside the 2 inch socket rather than projecting like a reducing coupling, which matters when the tee is tight to a stud or a cabinet back.
7) How many Spears DWV flush bushings come in a carton?
They ship 30 pieces per carton. That is the stocking unit contractors and distributors buy for common reductions like 3 x 2, where you go through them on nearly every bathroom group.
