SharkBite U088LF 3/4" x 3/4" FNPT Push-Fit Adapter, Lead-Free

The SharkBite U088LF is a 3/4" x 3/4" FNPT push-fit adapter built for rough-in plumbers who need a fast, code-friendly transition between push-fit tubing and female iron pipe thread without soldering, clamps, unions, or glue. This lead-free fitting connects copper tubing, CTS CPVC, and PEX in any combination on the push-fit end, while the 3/4" FNPT end threads directly onto standard male pipe connections. Fittings in this SharkBite line are certified to 200 PSI and 200 degrees F (93 degrees C), making them suitable for hot and cold water rough-in work behind walls, under floors, and in mechanical rooms where quick, reliable connections matter.

Key Features

  • Trade Size: 3/4" x 3/4" FNPT connection for standard rough-in transitions to threaded fixtures, valves, or fittings.
  • Multi-Pipe Compatibility: Push-fit end accepts copper tubing, CTS CPVC, and PEX, and connects all three pipe types to one another in any combination.
  • No-Tool Installation: Instant push-fit connection requires no soldering, clamps, unions, or glue, cutting install time on rough-in jobs.
  • Removable & Reusable: Stainless steel teeth grip the pipe and an O-ring seals the joint; the connection disassembles quickly with a simple disconnect tool so fittings and valves can be changed and reused.
  • Rotatable After Assembly: The push-fit end can be rotated after installation, giving plumbers flexibility to align fittings in tight wall or floor cavities.
  • Pressure & Temperature Rated: Certified to 200 PSI and 200 degrees F (93 degrees C) for demanding rough-in supply line applications.
  • Lead-Free Construction: Manufactured as a lead-free fitting for potable water rough-in use.

Why SharkBite?

Rated to 200 PSI and 200 degrees F and built lead-free, this adapter is a dependable choice for professional rough-in work where speed and a secure, code-appropriate connection both matter.

SharkBite U088LF – Frequently Asked Questions

1) Will the SharkBite U088LF push-fit adapter connect 3/4 inch PEX to a threaded male pipe nipple?
Yes. The U088LF has a 3/4 inch push-fit socket on one end and a 3/4 inch FNPT female thread on the other, so it threads straight onto a standard 3/4 inch male pipe connection and takes 3/4 inch PEX on the push side. The push end also accepts copper tubing and CTS CPVC, so you can transition any of those three to iron pipe thread with one fitting.
2) Can I use a SharkBite U088LF adapter on a hot water line or at a water heater?
Yes. The U088LF is certified to 200 PSI and 200 degrees F (93 degrees C), which covers hot and cold potable supply, including water heater and supply line connections. It is a lead-free fitting, so it is appropriate for potable water rough-in.
3) Do I need a crimp tool, solder, or glue to install a 3/4 inch SharkBite push-fit adapter?
No tools are needed to make the joint. The U088LF is an instant push-fit connection, no soldering, clamps, unions, or glue. Stainless steel teeth grip the pipe and an O-ring seals it. You will want a SharkBite disconnect clip or tongs to take it apart, and the pipe still has to be cut square and deburred before insertion.
4) Can the SharkBite U088LF be taken apart and reused, or is it a one-time fitting?
It comes apart and goes back on. The push-fit end releases with a simple disconnect tool, so the adapter can be pulled off, moved, and reused, which is useful when you are swapping a valve or re-aligning a run rather than scrapping the fitting.
5) Will the U088LF push-fit adapter join copper to PEX in a repipe?
Indirectly, yes. The push-fit side takes copper, CTS CPVC, or PEX, and SharkBite fittings in this line connect all three pipe types to one another in any combination. The U088LF itself has only one push socket, the other end being 3/4 inch female NPT, so for a straight copper-to-PEX splice with no thread involved you want a push-fit coupling instead.
6) Does the SharkBite U088LF meet lead-free requirements for potable water?
The U088LF is built as a lead-free fitting and carries a no-lead designation, which is what inspectors look for on potable water rough-in in residential and commercial work.
7) Can I rotate a SharkBite push-fit adapter after it is pushed on to line up a fixture?
Yes, the push-fit end rotates after assembly. That matters in tight wall and floor cavities where you need to swing the threaded side into alignment with a valve or fixture without pulling the joint apart.
8) Is the SharkBite U088LF a single fitting or sold in a pack?
The U088LF 3/4 inch FNPT adapter is packaged 6 each, so a single order covers a multi-fixture rough-in rather than one connection.
