Spears 837 Series PVC Schedule 80 Reducing Bushing, SPGxSOC

The Spears 837 Series Reducing Bushing is a Schedule 80 PVC fitting engineered to transition pipe and conduit runs between two nominal sizes, available in 1/2" x 3/4" for this configuration. Built with a spigot x socket (SPGxSOC) connection, it allows a smaller pipe to be inserted directly into a larger socket fitting, valve, or piece of equipment without requiring an intermediate coupling. The heavy-wall Schedule 80 PVC construction provides added pressure capability, impact resistance, and long-term durability compared to thinner-wall Schedule 40 fittings, making the 837 Series well suited for demanding piping and conduit systems. As part of the Spears line of PVC and CPVC fittings and valves, this reducing bushing gives installers a simple, economical way to step down pipe diameter at valves, tees, unions, or equipment ports while maintaining a solvent-weld solid connection.

Key Features

  • Trade Size: 1/2" x 3/4" reducing configuration for stepping down pipe or conduit runs.
  • Durable Construction: Schedule 80 PVC material offers strong corrosion resistance and a heavier wall thickness than Schedule 40 for demanding applications.
  • Spigot x Socket (SPGxSOC) Connection: The spigot end inserts directly into a socket fitting, valve, or equipment port, while the socket end accepts standard pipe, simplifying size transitions without extra couplings.
  • Reducing Bushing Design: Allows a smaller diameter pipe to be joined into larger fittings, valves, or equipment ports in a single solvent-weld connection.
  • Schedule 80 Rating: Rated for higher pressure and impact resistance than standard Schedule 40 PVC fittings, supporting more demanding pressure piping applications.
  • PVC Material: Corrosion- and chemical-resistant PVC construction resists the degradation common to metallic fittings in wet or corrosive environments.

Spears 837-101 – Frequently Asked Questions

1) What does a spigot x socket reducing bushing like the Spears 837 actually do in a pipe run?
The Spears 837 reducing bushing steps a run down one size in a single solvent-weld joint. The spigot end is sized like pipe, so it glues into a larger socket on a fitting, valve or equipment port; the socket end accepts the smaller pipe. That removes the need for a separate coupling or an oversized reducing fitting at the transition, and it cuts a leak point.
2) Is the Spears 837 bushing Schedule 80 or Schedule 40, and can I use it in a Schedule 40 PVC system?
It's a Schedule 80 PVC fitting, heavier wall than Schedule 40 and rated for higher pressure and impact. Schedule 80 and Schedule 40 PVC share the same outside diameters at a given trade size, so the 837 solvent-welds to Schedule 40 pipe without an adapter. The system still gets rated by its weakest component, so Sch 40 pipe in the run governs the working pressure, not the fitting.
3) Can I thread this Spears bushing into a female NPT port?
No. The 837 is solvent-weld only, spigot on one end and socket on the other. Neither end is threaded, so it won't go into an FPT port on a pump, tank or valve. For that you need a Schedule 80 PVC male adapter (MPT x socket) instead.
4) What sizes does the Spears 837 PVC reducing bushing come in?
Two trade sizes are offered: 1/2 inch, part number 837-101, and 3/4 inch, part number 837-131. Order by the trade size of the connection you need to make, and confirm which end of the step the number refers to in the Spears Schedule 80 dimensions data before you cut.
5) Will a PVC bushing hold up where metal fittings are corroding?
Yes. The 837 is molded PVC, which resists corrosion and chemical attack in wet environments where galvanized or brass fittings pit and scale. It's a common swap in process piping, irrigation and industrial lines for that reason. PVC is not for hot water or high-temperature service, though; a CPVC fitting is the right call there.
6) Do I need a reducing bushing or a reducer coupling for stepping down pipe size?
Use the bushing when the larger size is already a socket you have to fill, for instance a valve inlet, a tee branch or a union that's one size up from your pipe. Use a reducer coupling when you are joining two lengths of pipe of different sizes in open line. The 837 bushing is the shorter, lower-cost option and avoids adding an extra coupling at the transition.
7) Where do dimensions and laying length for the Spears 837 Schedule 80 bushing come from?
Spears publishes socket depth, overall length and weight for its Schedule 80 fittings in the Schedule 80 dimensions sheet and the PVC Schedule 80 fittings dimensions and weights document, both carried with the 837 Series. Pull socket depth from there when you're figuring insertion allowance on a tight run.
8) Is the Spears 837 bushing OK for electrical conduit as well as pressure piping?
It's used for both PVC pipe and conduit size transitions. On the piping side it goes into Schedule 80 pressure runs and process piping needing a reduced outlet. Solvent cement rated for the material and size is required on both the spigot and socket joints and is not supplied with the fitting.
