Spears 479 Schedule 40 PVC Deep Socket Coupling
Spears Schedule 40 PVC Deep Socket Coupling is a solvent-weld fitting engineered to join two lengths of Schedule 40 PVC pipe into a single continuous, pressure-rated run. Built from durable PVC and available in 1-1/2", 2", and 3" trade sizes, this deep socket coupling provides extra socket depth on each end for a larger bonding surface area, delivering a stronger, more reliable solvent-cemented joint than standard couplings. Whether you need to extend or repair a Schedule 40 PVC pipe run, this coupling offers a straightforward, code-compliant connection across the full size range distributors and contractors rely on.
Key Features
- Trade Size Range: Available in 1-1/2", 2", and 3" for use with matching Schedule 40 PVC pipe diameters.
- Durable Construction: Molded PVC body resists corrosion, chemical attack, and degradation in demanding piping environments.
- Deep Socket Design: Extended socket depth on both ends increases the bonded contact area with the pipe, improving joint strength and leak resistance versus shallow-socket couplings.
- Schedule 40 Compatibility: Sized and rated to mate properly with Schedule 40 PVC pipe for consistent, code-compliant pressure performance across all available sizes.
- Solvent-Weld Connection: Designed for standard PVC solvent cement installation, creating a permanent, rigid joint once cured.
- Straight Coupling Configuration: Connects two pipe ends in-line, making it easy to extend runs or splice in repair sections.
- Bulk Packaging: Supplied in bulk cartons to simplify inventory management for plumbing supply houses and installation crews.

Spears 479-015 – Frequently Asked Questions
1) What sizes does the Spears deep socket PVC coupling come in?
Three trade sizes: 1-1/2 inch (part 479-015), 2 inch (479-020), and 3 inch (479-030). Each is sized to mate with Schedule 40 PVC pipe of the matching nominal diameter, socket on both ends.
2) Is this coupling threaded or does it get glued?
Glued. Both ends are solvent weld sockets, so you prime and cement the pipe into the fitting. There are no threads on the 479 coupling. Once cured the joint is permanent and rigid, so cut it out if you ever need to open the run.
3) Will this PVC coupling work on a hot water line?
No. It is a PVC fitting, and PVC is for cold water and ambient-temperature pressure piping. For hot water distribution you want CPVC fittings instead. Spears builds both, so match the fitting material to the pipe material already in the run.
4) What is the difference between a deep socket PVC coupling and a standard coupling?
Socket depth. The Spears 479 coupling has an extended socket on each end, so more of the pipe wall sits inside the fitting and the solvent cement has a larger bonding surface. That yields a stronger, more leak-resistant joint than a shallow-socket coupling. Same in-line straight configuration otherwise, and it goes together with standard PVC solvent cement.
5) Can I use a Schedule 40 PVC coupling on Schedule 80 pipe?
The outside diameter of Sch 40 and Sch 80 PVC is the same at a given trade size, so a Sch 40 socket will accept Sch 80 pipe physically. But the fitting is a Schedule 40 part and carries Schedule 40 pressure performance, so on a Sch 80 system it becomes the weak point. If the system was specified Schedule 80, use a Schedule 80 coupling.
6) Can I use this coupling to splice a repair section into an existing PVC line?
That is one of its normal uses. Cut out the damaged section, square and deburr the pipe ends, then solvent weld a replacement length in with a coupling at each end. The deeper socket gives you more bonded surface on each side of the repair. Note that with both ends already cemented in place you may need a repair coupling or union on the final joint, since a deep socket coupling has to slide fully onto a pipe end to seat.
7) Does a deep socket coupling need a longer piece of pipe stubbed into it?
Yes, plan your cuts for it. Because the socket runs deeper than a standard coupling, each pipe end has to insert further to bottom out. When you are measuring a replacement length between two fixed points, add the extra take-up on both ends or the piece will come up short of full socket engagement.
8) How is the Spears 479 coupling packaged for stocking?
Fifty each per carton, which is why distributors and plumbing supply houses stock it by the box rather than the piece. Handy for crews doing repeated repair splices on the same size line.
9) What material is the Spears 479 coupling and how does it hold up to chemicals?
Molded PVC. It resists corrosion and chemical attack and does not degrade the way metal fittings do in wet or corrosive environments, which is why it turns up in commercial pressure piping as well as residential water and drain work.
