Spears 437167 Schedule 80 PVC SPGxSOC Reducing Bushing

The Spears Schedule 80 PVC SPGxSOC Reducing Bushing transitions between two pipe sizes within a single Schedule 80 PVC pressure piping run, using a spigot-by-socket (SPGxSOC) connection for a secure, solvent-welded joint. This reducing bushing is available in sizes ranging from 1-1/4" x 1/2" up to 6" x 4", molded from rigid, corrosion-resistant PVC for reliable pressure-rated transitions from a larger trade size down to a smaller branch or outlet without adding a separate coupling. Whether stepping down a 2" run to a 1" branch or transitioning a 6" main to a 4" outlet, this bushing simplifies the connection without adding extra components. As part of the Spears Schedule 80 fitting line, every size is built to standard dimensional tolerances for consistent fit-up with other Schedule 80 PVC pipe and fittings.

Key Features

  • Reducing Size Range: Available in configurations from 1-1/4" x 1/2" up to 6" x 4", stepping down pipe size within a single fitting instead of adding a separate reducer coupling.
  • Schedule 80 PVC Construction: Molded from rigid, corrosion- and chemical-resistant PVC suitable for demanding pressure piping applications.
  • SPGxSOC Connection: Spigot end fits inside a socket fitting or valve while the socket end accepts pipe, for a compact, low-profile transition joint.
  • Solvent-Weld Joint: Designed for solvent cementing to Schedule 80 PVC pipe and fittings for a permanent, leak-resistant connection.
  • Consistent Fit-Up: Manufactured to standard PVC fitting dimensions for reliable assembly with compatible Schedule 80 components across every size in the range.

Technical Specifications

  • Product Material: PVC
  • Connection Type: Spigot x Socket
  • Product Size: 1/2" - 1-1/4"

Typical Applications

  • Pressure Piping Systems Requiring a Size Transition
  • Industrial and Commercial PVC Piping Networks

Spears 437-167 – Frequently Asked Questions

1) What sizes does the Spears Schedule 80 PVC reducing bushing come in?
The Spears Schedule 80 reducing bushing covers a wide span of reductions: 1-1/4 x 1/2, 1-1/4 x 3/4, 1-1/2 x 3/4, 1-1/2 x 1, 2 x 1/2, 2 x 3/4, 2 x 1, 2 x 1-1/2, 2-1/2 x 1-1/2, 2-1/2 x 2, 3 x 1, 3 x 1-1/4, 3 x 1-1/2, 3 x 2, 4 x 3, 5 x 4, and 6 x 4 inches. The first number is the spigot end that goes into the larger fitting, the second is the socket that takes the smaller pipe. So a 3 x 1 steps a 3 inch line down to a 1 inch branch in one fitting.
2) Does a SPGxSOC reducing bushing go inside a fitting, or does pipe slide over it?
It goes inside. The spigot end of the Spears bushing is sized like pipe, so it solvent welds into the socket of a larger tee, coupling, elbow, or valve. The smaller pipe then cements into the socket end of the bushing. That is what makes it a flush, low-profile reduction: nothing sticks out the way a reducer coupling would. If the larger side of your transition is a pipe end rather than a fitting socket, a bushing is the wrong part and you want a reducer coupling or a bell reducer instead.
3) Will a Spears Schedule 80 bushing fit Schedule 40 PVC pipe?
Yes on the socket side. Schedule 40 and Schedule 80 PVC share the same outside diameters and the same socket dimensions by trade size, so a Schedule 80 bushing solvent welds to Schedule 40 pipe of the matching size. What you do not get is a Schedule 40 pressure rating upgrade, and the system is still limited by the lowest rated component in the run. The heavier Schedule 80 wall is why these are specified on industrial and chemical lines.
4) Can I put a Schedule 80 PVC bushing on a hot water or steam line?
PVC is a cold-water and ambient-temperature material, and this Spears bushing is rigid PVC. It belongs on cold pressure lines, process chemical piping, and irrigation. For heated service the material to look for is CPVC, which carries a higher temperature rating in the same Schedule 80 socket dimensions. Putting PVC on hot lines is the most common way these fittings fail in the field.
5) Can I use a Schedule 80 PVC reducing bushing on a pressure line?
Yes. This is a Schedule 80 rigid PVC fitting built for pressure piping, and it is solvent welded on both ends for a permanent joint. Common uses are industrial and commercial PVC networks, chemical process lines, and irrigation and water distribution. Note that a bushing reduces the wall available at the joint compared to a reducer coupling, so on high-cycle or heavily surged lines many specs call for a reducer bushing only where the run allows it.
6) Do I need PVC primer and cement for a Spears reducing bushing, or does it thread in?
There are no threads on this one. Both ends of the Spears SPGxSOC bushing are solvent weld, so you need PVC primer and solvent cement rated for Schedule 80, and neither is included with the fitting. Order cement with the fitting if you do not have it on the truck. If you want a joint you can take back apart, a bushing is not it, and you would look at a threaded bushing or a union instead.
7) Why use a reducing bushing instead of a reducer coupling on a PVC line?
Space and part count. The bushing drops straight into a socket you already have, so a 2 x 1 reduction happens inside the existing fitting with no extra length added to the run. A reducer coupling needs pipe on both sides and adds a joint. On a retrofit where you are stepping an existing PVC run down to a smaller branch, the bushing is usually the only way to make the change without cutting and re-fitting. Where the larger side terminates in bare pipe instead of a socket, you cannot use a bushing.
8) What is the part number for a Spears 2 inch to 1 inch Schedule 80 reducing bushing?
That one is Spears 837-249. For the other common 2 inch reductions: 2 x 1/2 is 437-247, 2 x 3/4 is 837-248, and 2 x 1-1/2 is 837-251. Give the pair of sizes when you order, because the number changes with every combination and the prefix changes between 437 and 837 across the range.
9) Will a Spears reducing bushing mate with another manufacturer's Schedule 80 PVC fittings?
Yes. These are molded to standard PVC fitting dimensions, so the sockets and spigots match other Schedule 80 PVC pipe and fittings by trade size regardless of who made them. If you are patching into an existing run and do not know the original brand, the trade size and the schedule are what you need to confirm, not the manufacturer.
