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

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.
