Spears 838-072 SCH80 PVC Reducing Bushing, 1/2" x 1/4" SPGxFPT

The Spears 838-072 is a Schedule 80 PVC reducing bushing designed to transition pipe size from 1/2" down to 1/4" using a spigot-by-female-pipe-thread (SPGxFPT) connection configuration. Molded from high-quality PVC compound, this fitting combines chemical resistance, dimensional stability, and long-term durability for use in pressure-rated plumbing and industrial piping systems. The spigot end inserts directly into a compatible socket fitting, while the female pipe thread outlet accepts a standard male-threaded component, allowing installers to step down pipe size and add a threaded connection point in a single fitting.

Key Features

  • Size Reduction: Reduces from 1/2" to 1/4" pipe size, allowing installers to transition to smaller-diameter threaded components without additional fittings.
  • SPGxFPT Connection: Spigot end fits inside a socket-style fitting while the female pipe thread (FPT) end accepts male-threaded valves, gauges, or accessories.
  • Schedule 80 Construction: Heavier wall thickness than Schedule 40 fittings, providing increased pressure handling and structural strength for demanding plumbing and industrial applications.
  • Durable PVC Material: Manufactured from PVC compound that resists corrosion and degradation from a wide range of fluids commonly encountered in plumbing, irrigation, and process piping.
  • Compact, Space-Saving Design: Combines a size reduction and a threaded transition into a single fitting, minimizing the number of joints and potential leak points in a piping run.
  • Threaded Outlet Versatility: The FPT outlet simplifies connection of male-threaded components directly to the reduced port without requiring an additional adapter.
  • Consistent Fit and Finish: Precision-molded dimensions help ensure proper engagement with mating socket and threaded fittings for a secure, leak-resistant joint.
  • Wide Application Range: Suitable for potable water, drainage, irrigation, and industrial fluid-handling systems where PVC piping materials are specified.

Why Spears 838-072?

Spears reducing bushings are manufactured to Schedule 80 dimensional standards, delivering the wall thickness and structural integrity needed for demanding PVC piping systems. The SPGxFPT configuration pairs a spigot inlet with a threaded outlet, giving installers a dependable way to reduce pipe size while adding a threaded connection point in a single component. Built from durable PVC material, the 838-072 is engineered for plumbing professionals who need a precise, corrosion-resistant size transition without sacrificing pressure performance.

Spears 838-072 – Frequently Asked Questions

1) What does SPGxFPT mean on the Spears 838-072 bushing, and how does it install?
SPG is a spigot end, sized like pipe so it inserts into a 1/2 inch socket fitting and is solvent welded there. FPT is female pipe thread, so the 1/4 inch outlet takes a male-threaded part. You are not gluing the threaded side, and you are not gluing the spigot into a threaded port either: one joint is cement, the other is thread sealant on the male threads.
2) Can I glue the spigot end of the 838-072 into a 1/2 inch PVC pipe?
No. The spigot end is the same outside diameter as 1/2 inch pipe, so it goes INTO a socket (a coupling, tee, elbow, or valve socket), not into pipe. If what you have is a 1/2 inch pipe end, you need a socket fitting between them, or a bushing with a socket inlet instead of a spigot.
3) I need to mount a 1/4 inch pressure gauge on a 1/2 inch PVC line. Is the Spears 838-072 the right fitting?
That is exactly what it does. The 1/4 inch FPT outlet accepts a male NPT gauge, sensor, injection port, or small valve, and the spigot inlet drops into any 1/2 inch socket port you already have. One fitting does the size reduction and the threaded takeoff, so there is no second adapter and no extra joint to leak.
4) How do I seal the threaded side of a PVC reducing bushing without cracking it?
Use PTFE tape or a PVC-compatible thread sealant on the male threads and hand tighten, then no more than one to two turns past hand tight with a strap wrench. Plastic female threads split from over-torque, not from under-torque, and a 1/4 inch port like the one on the 838-072 is the easiest size to crack. Never use metal pipe wrenches on the hex.
5) Is dark gray Schedule 80 PVC OK for potable water and for chemical feed lines?
The 838-072 is specified for potable water, drainage, irrigation, and industrial fluid handling, and it is used in water treatment and chemical handling piping. For a specific chemical, check that chemical against a PVC compatibility chart first, and remember PVC is not for compressed air or hot water service.
6) What is the exact part number for the Spears 1/2 x 1/4 inch Sch 80 PVC reducing bushing?
Spears 838-072. The 838 series is the Sch 80 PVC SPGxFPT reducing bushing, and the -072 suffix is the 1/2 inch spigot by 1/4 inch FPT combination. Order by 838-072 and you get that size pairing.
7) Where can I get laying lengths and socket depths for Spears Schedule 80 PVC fittings?
Spears publishes a Schedule 80 dimensions sheet and a dimensions and weights document covering the Sch 80 PVC fitting line, including the 838 bushings. Those are the numbers to use when you are figuring takeout for a tight run or checking clearance around an existing valve.
