SharkBite U070LF 3/8" x 1/2" FNPT Push-to-Connect Connector

The SharkBite U070LF is a 3/8" x 1/2" FNPT push-to-connect connector designed for rough-in plumbers and contractors who need a fast, tool-free transition from push-fit tubing to female iron pipe thread (FNPT) connections. This fitting lets you join 3/8" push-to-connect tubing directly to a 1/2" FNPT threaded connection without soldering, clamps, or unions, making it a practical choice for repairs, retrofits, and new installations where speed and reliability behind the wall or under the floor matter. Each unit ships in a carton quantity of 6 ea, making it easy for plumbing contractors and service trucks to keep stock on hand for common supply-line and fixture connections.

Key Features

  • Trade Size: 3/8" push-to-connect end x 1/2" FNPT threaded end for transitioning between tubing sizes and threaded fittings.
  • Connection Type: Push-to-connect on one end for tool-free installation onto compatible tubing, with a 1/2" FNPT threaded end for mating to standard male iron pipe (MIP) threaded fixtures, valves, and stops.
  • Configuration: Reducing connector design bridges a 3/8" push-fit tubing run down to a 1/2" female threaded connection point, useful where fixture supply threads differ from the tubing size in the wall.
  • Rough-In Application: Suited for behind-the-wall and under-floor plumbing connections where a quick, dependable transition fitting is needed without opening the wall for soldering.
  • Packaging: Supplied 6 ea per pack for contractors and plumbing supply houses stocking common transition connectors.

SharkBite U070LF – Frequently Asked Questions

1) What does the SharkBite U070LF connector actually connect to on each end?
The U070LF is a two-end transition fitting: one end is a 3/8 inch push-to-connect socket for tubing, the other is a 1/2 inch FNPT female thread. The threaded end screws onto a male iron pipe (MIP) thread, so it mates with standard MIP stops, valves and fixture nipples. The push end goes onto 3/8 inch tubing with no solder, no clamps and no unions.
2) I have 1/2 inch tubing in the wall. Will the U070LF work?
No. The push-fit end on the U070LF accepts 3/8 inch tubing only, and the 1/2 inch dimension refers to the female pipe thread, not a tubing size. If your tubing run is 1/2 inch, you need a push-fit fitting whose socket is sized 1/2 inch. Reading the size as 3/8 push x 1/2 FNPT is the thing buyers most often get backwards on this part.
3) Will the 1/2 inch FNPT end thread onto a standard 1/2 inch angle stop or valve?
Yes, if that stop or valve has a 1/2 inch male iron pipe thread. The connector's female end is 1/2 inch FNPT and is intended to mate with standard MIP threaded fixtures, valves and stops. Check whether your stop is MIP or compression first, because a compression-inlet stop has no thread for this fitting to grab.
4) Do I need a tool or a crimper to install a SharkBite U070LF push-fit connector?
No tool is needed on the push-to-connect side. You push the fitting onto the 3/8 inch tubing and it grips and seals. The 1/2 inch FNPT side is threaded, so that half is made up like any female iron pipe connection with thread sealant and a wrench on the male part. No soldering or clamping is involved, which is why it works for repairs inside a wall cavity or under a floor where you cannot get a torch in.
5) Can I use a push-to-connect transition fitting behind drywall or under a floor, or does it have to stay accessible?
The U070LF is described for rough-in work behind the wall and under the floor, which is exactly where its advantage shows up: you get a dependable transition without opening a wall to run a torch. It is used in residential and commercial rough-in, supply line repairs and retrofits, and new construction. Local code still governs what you may conceal, so follow your inspector on concealed fittings.
6) Why would I use a push-fit FNPT connector instead of a compression or soldered adapter?
A compression adapter needs a nut and ferrule set correctly and a soldered adapter needs heat, flux and a dry line. The U070LF's push end makes up with hand pressure, so on a repair or retrofit where you are working in a cramped bay with water still in the system nearby, it is the faster transition. Where you are already sweating copper in open space and have the torch out, a soldered adapter is the conventional choice. The U070LF earns its place on the truck for speed on fixture and supply-line transitions.
7) How many SharkBite U070LF connectors come in a pack?
They ship 6 each per carton. That quantity suits a service truck or a shop stocking common transition fittings rather than a one-off repair, so plan on buying the full pack of six.
8) What is the SharkBite part number for the 3/8 x 1/2 FNPT push-fit connector?
The manufacturer part number is U070LF. It is the 3/8 inch push-to-connect by 1/2 inch FNPT connector in the SharkBite line, and that single MPN covers the item as sold.
