Spears Schedule 80 PVC Reducing Female Adapter, Socket x FPT

The Spears Schedule 80 PVC Reducing Female Adapter, Socket x FPT, is engineered for dependable, code-compliant transitions in pressure-rated PVC piping systems. Molded from heavy-wall Schedule 80 PVC, this reducing female adapter connects a socket-end pipe run down to a smaller female threaded (FPT) port, making it well suited for pump connections, valve hookups, gauge and instrument tie-ins, and other threaded transitions where a reduction in port size is required. Available in a range of reducing sizes to accommodate varying pipe diameters, it delivers the pressure capacity, corrosion resistance, and long service life PVC is known for in demanding plumbing, irrigation, and industrial process applications.

Key Features

  • Reducing Configuration: Female adapter steps down from a larger socket connection to a smaller female threaded (FPT) port, simplifying transitions between pipe sizes and threaded components.
  • Schedule 80 Construction: Heavy-wall Schedule 80 PVC provides increased pressure capacity and wall thickness compared to Schedule 40, supporting demanding pressure-piping applications.
  • Socket x FPT Connection: The socket end solvent-welds directly to PVC pipe, while the female threaded (FPT) end accepts male-threaded nipples, valves, pumps, and other equipment connections.
  • Corrosion and Chemical Resistance: PVC construction resists rust, corrosion, and chemical attack that commonly degrade metallic fittings in industrial and municipal piping systems.
  • Lightweight, Job-Site Friendly: Significantly lighter than metal alternatives, reducing installer fatigue and simplifying handling, cutting, and solvent-welding in the field.
  • Dimensional Consistency: Manufactured to standard PVC fitting dimensions for reliable fit-up with compatible Schedule 80 PVC pipe and threaded components.

Spears 835-131SR – Frequently Asked Questions

1) What size is the Spears 835-131SR Schedule 80 PVC reducing female adapter?
It's a 1 inch by 3/4 inch reducer: the socket end takes 1 inch Schedule 80 PVC pipe, and the threaded port is 3/4 inch FPT. So you solvent weld the 1 inch run into the socket and thread a 3/4 inch male-threaded nipple, valve, or gauge fitting into the other end.
2) Does the socket end of this PVC female adapter get glued or threaded?
Glued. The socket side is solvent welded to the pipe with PVC primer and cement, not threaded. Only the 3/4 inch FPT port takes threads, and that one gets a male-threaded component with thread sealant. Don't try to thread the 1 inch socket end.
3) Will a Schedule 80 PVC adapter fit Schedule 40 PVC pipe?
Yes on the socket side. Schedule 40 and Schedule 80 PVC pipe share the same outside diameter at a given nominal size, so 1 inch Sch 40 pipe solvent welds into the 1 inch Sch 80 socket. The difference is wall thickness, not OD. Just remember the system's pressure rating is set by the weakest component, so a Sch 40 pipe run doesn't get Sch 80 pressure capacity because of the fitting.
4) Can I use a Schedule 80 PVC female adapter to connect a pump or gauge to my pipe run?
That's exactly what it's for. The Spears 835-131SR steps a 1 inch glued pipe run down to a 3/4 inch female thread, which is the standard way to tie in pumps, valves, gauges, and instrument taps. The heavy-wall Schedule 80 body gives you more wall thickness at the threads than a Schedule 40 fitting would.
5) Is PVC or metal the better choice for a threaded adapter in a chemical or water treatment line?
PVC is the usual pick where corrosion is the problem. The Spears reducing female adapter is molded PVC, which resists rust and chemical attack that eats galvanized or black iron threaded fittings in municipal and process water systems. It's also far lighter to handle on the job. Where PVC gives ground is high temperature and mechanical abuse, so a hot line or a spot taking impact is still a metal application.
6) Why use a reducing female adapter instead of a bushing and a straight adapter?
One fitting instead of two. The 835-131SR handles the 1 inch to 3/4 inch step and the socket-to-thread transition in a single body, so you have one solvent weld joint rather than a bushing plus adapter stack. Fewer joints means fewer leak paths and less overall length eaten up in a tight pump or valve pocket.
7) What part number do I order for a 1 x 3/4 Spears Sch 80 PVC female adapter?
Spears part number 835-131SR. The 835 series is the Schedule 80 PVC socket x FPT female adapter, and the -131 suffix is the 1 inch socket by 3/4 inch FPT reducing size.
8) How is the Spears 835-131SR PVC adapter packaged for distributors?
It ships 200 each per case. That's the case quantity for the 1 x 3/4 reducing female adapter, which matters if you're stocking a shelf or buying against a project takeoff rather than pulling a handful of fittings.
