Spears 4137-130 1" x 1/2" CPVC CTS Red Reducer Bushing, Spigot x Socket

The Spears 4137-130 is a 1" x 1/2" CPVC CTS reducer bushing engineered to transition between two different pipe diameters within a CTS (copper tube size) piping system. Molded from red CPVC for easy visual system identification, this fitting features a spigot x socket connection that allows it to slip into an existing socket fitting while accepting a smaller pipe on the opposite end. Because it uses a bushing profile rather than a full-body reducer coupling, the 4137-130 is well suited to tight spaces where a standard reducer will not fit. Like other Spears CPVC CTS fittings, it is designed to be solvent-welded for a permanent, leak-resistant joint that meets the demands of professional piping installations.

Key Features

  • Trade Size: 1" x 1/2" reducer bushing for stepping down from a larger CTS pipe run to a smaller branch line.
  • Durable Construction: CPVC CTS material offers corrosion and chemical resistance for demanding piping applications.
  • Connection Type: Spigot x socket ends allow the fitting to be solvent-welded directly into a mating socket fitting on one end and onto a smaller pipe on the other.
  • Color-Coded Red: Molded in red CPVC for quick visual identification within a piping system.
  • Compact Reducer Profile: Bushing-style design slips inside an existing socket fitting when a full-body reducer coupling will not fit the available space.
  • CTS Sizing: Copper tube size (CTS) dimensioning ensures compatibility with other CTS-based CPVC components in the system.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • CTS Piping System Size Reductions
  • Chemical-Resistant Piping Installations
  • Commercial and Residential Plumbing Systems
  • Pipe Transition and Retrofit Projects
  • Tight-Space Fitting Transitions

Why Spears?

Spears 4137-130 – Frequently Asked Questions

1) What does spigot x socket mean on this 1 inch by 1/2 inch CPVC bushing, and which end goes where?
The spigot end is the 1 inch male end that slips into the socket of an existing 1 inch CTS fitting, such as a tee or coupling. The socket end is the 1/2 inch female end that accepts 1/2 inch CTS CPVC pipe. So you are reducing a 1 inch fitting port down to a 1/2 inch branch, not pipe-to-pipe. Both ends are solvent-welded.
2) Can I use a reducer bushing instead of a reducing coupling in a tight wall cavity?
That is exactly what the bushing profile is for. Because the 4137-130 seats inside an existing socket rather than adding a full coupling body to the run, it takes up less linear space than a standard reducer coupling. Useful where a wall cavity, joist bay, or equipment clearance will not let you add a full-body reducer. The trade-off is that it only works where there is already a 1 inch socket to receive it, if you need pipe-to-pipe reduction mid-run, use a reducing coupling.
3) Does this CPVC reducer bushing thread in, or does it need solvent cement?
No threads on either end. Both the 1 inch spigot and the 1/2 inch socket are solvent-weld. You will need CPVC primer and CPVC solvent cement rated for the material, neither is supplied with the fitting. The joint is permanent once cured, so dry-fit and mark your depth before cementing.
4) Is CPVC the right choice over PVC for a hot water branch line?
CPVC is the one of the two rated for hot water distribution, PVC is cold water and drainage only. The 4137-130 is CPVC, and it also carries the corrosion and chemical resistance that makes CPVC common on chemical-resistant piping as well as commercial and residential potable systems. Do not substitute a PVC bushing into a CPVC hot line.
5) Why is this Spears CPVC fitting red instead of the usual tan or cream?
The red molding is for visual system identification. Spears molds this CTS fitting in red CPVC so installers and anyone servicing the building later can tell the run apart at a glance and avoid tying into the wrong system or mixing incompatible components. The color does not change the material, it is CPVC either way.
6) What is the Spears part number for a 1 inch to 1/2 inch CPVC CTS reducer bushing?
Spears 4137-130. That is the manufacturer part number for the 1 inch by 1/2 inch CTS reducer bushing in red CPVC with spigot x socket ends. Order by that number to be sure you are getting the CTS version rather than an IPS bushing.
