SharkBite UIP4020 PVC Coupling, 1" CTS x 1" IPS

The SharkBite UIP4020 is a 1" CTS x 1" IPS PVC coupling built for rough-in plumbers who need a reliable transition fitting between copper tube size (CTS) and iron pipe size (IPS) PVC pipe runs. Molded from durable PVC, this coupling is designed to join two differently-sized PVC pipe ends into a single continuous line without the need for solvent welding at this connection point. It ships in a 3-piece pack, making it a practical stock item for contractors and service plumbers who regularly encounter CTS-to-IPS transitions on residential and light commercial jobs. As a behind-the-wall rough-in component, this fitting is intended to be installed within the wall cavity, under a floor, or in a mechanical space as part of a larger PVC piping system, not as a visible or decorative plumbing part.

Key Features

  • Trade Size: 1" CTS x 1" IPS, sized to transition between copper tube size and iron pipe size PVC pipe runs.
  • Durable Construction: Molded PVC body for use in standard PVC pipe systems.
  • Coupling Configuration: Straight coupling design joins two pipe ends of differing size classifications (CTS to IPS) into one continuous run.
  • Job-Ready Pack Size: Supplied 3 pieces per package, allowing plumbers to stock multiple fittings for a single job or service truck inventory.
  • Manufacturer Documentation: Backed by SharkBite spec sheet, warranty, and installation documentation for reference during planning and installation.

SharkBite UIP4020 – Frequently Asked Questions

1) What does the SharkBite UIP4020 coupling actually connect?
The UIP4020 is a straight PVC coupling that transitions 1 inch CTS (copper tube size) pipe to 1 inch IPS (iron pipe size) pipe. Both ends are nominally 1 inch, but CTS and IPS pipe have different outside diameters, so a standard 1 inch coupling will not join them. This fitting bridges that size mismatch in a single part.
2) Do I need to solvent weld the SharkBite UIP4020, or does it push on?
It's a push-fit connection, so no solvent cement, primer, or cure time is needed at this joint. That matters on repairs where the line is still damp or where you can't wait on glue to set.
3) Can I use the UIP4020 PVC coupling on an exposed or finished plumbing run?
No. It's a behind-the-wall rough-in component, meant for inside a wall cavity, under a floor, or in a mechanical space. It isn't a trim or decorative fitting, so for anything visible you want a chrome or finished transition instead.
4) Is the SharkBite UIP4020 made of plastic or brass?
PVC. It's a molded PVC body for use in standard PVC pipe systems, not a brass push-fit fitting, so it belongs in a PVC run rather than as a copper or PEX transition.
5) What part number should I order for a 1 inch CTS to 1 inch IPS PVC transition from SharkBite?
SharkBite UIP4020. That's the manufacturer part number, and it's the single model offered for the 1 inch CTS x 1 inch IPS PVC coupling.
6) Will the UIP4020 work for a repair on existing PVC pipe, or only new construction?
Both. It's used for repair and replacement of existing PVC piping as well as new construction supply and drain line installation. The push-fit ends are what make it workable on a repair, since there's no cement cure to wait on.
7) How many couplings come in a pack of the SharkBite UIP4020?
Three pieces per pack. That's a truck-stock quantity rather than a single fitting, so if you only need one transition you'll still have two spares.
