Spears 435005 Schedule 80 PVC Socket x FPT Female Adapter

The Spears 435005 Schedule 80 PVC Socket x FPT Female Adapter provides a dependable socket x FPT (SOCXFPT) transition between solvent-weld PVC pipe and threaded fittings or valves. Molded from heavy-duty Schedule 80 PVC, this adapter is built for demanding pressure-piping systems where strength and corrosion resistance are essential. This family is available in trade sizes ranging from 1/2" through 5", including 3/4", 1", 1-1/4", 1-1/2", 2", 2-1/2", 3", and 4", and each unit ships in a pack of 10 ea for efficient inventory management on multi-fitting jobs.

Key Features

  • Size Range: Offered in trade sizes from 1/2" through 5" (1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 2-1/2", 3", 4", 5") to fit a wide range of piping runs.
  • Socket x FPT Configuration: The SOCXFPT design allows one end to solvent-weld directly to PVC pipe while the female-threaded end accepts male-threaded fittings, valves, or equipment connections.
  • Schedule 80 PVC Construction: Heavy-wall Schedule 80 PVC delivers superior strength and corrosion resistance compared to lighter-schedule plastics, suited for pressure piping and industrial-grade applications.
  • Reliable Transition Fitting: Simplifies the connection between rigid PVC piping runs and threaded components without requiring additional couplings or adapters.
  • Chemical and Corrosion Resistance: PVC material resists corrosion, rust, and many common chemicals found in plumbing and process piping environments.
  • Convenient Packaging: Supplied 10 each per pack, streamlining inventory management for installers and distributors handling higher-volume jobs.
  • Lightweight Yet Durable: PVC construction keeps the fitting lightweight for easy handling while still providing long-term durability in piping systems.

Spears 435-005 – Frequently Asked Questions

1) What does the Spears 435 female adapter connect to on each end?
One end is a solvent-weld socket that cements onto Schedule 80 PVC pipe; the other is FPT (female pipe thread) that receives a male-threaded fitting, valve, or piece of equipment. That socket x FPT arrangement is what lets you go from a glued PVC run straight into a threaded connection without adding a coupling.
2) What sizes does the Spears 435 Schedule 80 PVC female adapter come in?
Trade sizes run 1/2 inch through 5 inch: 1/2, 3/4, 1-1/4, 1-1/2, 2, 2-1/2, 3, 4 and 5 inch, ordered as 435-005 through 435-050. The trade size is both the pipe size for the socket and the thread size on the FPT end, so a 2 inch adapter (435-020) takes 2 inch Sch 80 pipe and 2 inch NPT male threads.
3) Can I use a Schedule 80 female adapter on Schedule 40 PVC pipe?
Yes. Sch 40 and Sch 80 PVC share the same outside diameters at a given trade size, so a 435 series socket cements onto Sch 40 pipe of the same size. What you do not get is Sch 40 pressure ratings improving; the run is only as strong as the lighter pipe. The heavier Sch 80 wall on the fitting is there for pressure piping and industrial service.
4) Do I need Teflon tape or thread sealant on the threaded side of a PVC female adapter?
The FPT side is a tapered pipe thread and needs a sealant; use PTFE tape or a plastic-safe thread paste. The socket side is a solvent-weld joint, so it needs PVC primer and cement instead, not sealant. None of that is supplied with the fitting.
5) Should I use a female adapter or a male adapter for a PVC-to-threaded transition?
The 435 series female adapter is the one to use when the mating component has male threads, such as a valve nipple, pump port, or threaded equipment stub. If the component you are tying into has a female-threaded port, you want the male adapter (socket x MPT) instead. Both put the glued socket on the pipe side; the only difference is which gender ends up on the threaded connection.
6) Is this PVC adapter suitable for chemical or process piping, or only water?
PVC resists corrosion, rust, and many common chemicals, and the 435 series is used in industrial and commercial plumbing, chemical and process piping, irrigation, and water distribution as well as general PVC pressure systems. Check the specific chemical and temperature against a PVC compatibility chart before committing; PVC has limits that Schedule 80 wall thickness does not remove.
7) Can I thread a metal male nipple into a PVC female adapter?
Mechanically yes, the FPT socket takes any standard male pipe thread, but over-tightening a steel or brass nipple into a plastic female thread is the most common way these fittings split. Hand tight plus one to two turns with tape is the working rule, and do not use the threads to pull the joint up square.
8) How many Spears 435 female adapters come in a pack?
Each is supplied 10 each per pack, so a single order line covers ten fittings. Worth knowing if you are pricing a job that only needs two or three transitions.
