Sharkbite/cash Acme U648LFA 1/2 in 45 Degree Push-connect Elbow

Product Description

The SHARKBITE/CASH ACME U648LFA is a 1/2 inch push-to-connect 45 degree elbow fitting designed for plumbing and radiant heating systems. It forms a 45 degree directional change in the pipe run without soldering, clamps, unions, or glue. A specially formulated O-ring creates the seal when the pipe is inserted to the correct depth. Rated to 200 degrees F and 200 psi, this fitting is built for potable water and radiant heating service. Licensed plumbers and experienced trade installers handle this type of fitting in both new construction and retrofit applications.

The U648LFA is suited for residential and light commercial plumbing and hydronic radiant heating installations. It is rated for potable water systems and requires no access panels after installation. The 45 degree angle makes it the right choice when a 90 degree bend creates too sharp a turn for the pipe layout. It connects any combination of copper, PEX, CPVC, or PE-RT pipe, making it highly versatile across mixed-pipe systems.

Key Features

• Push-to-connect design — no soldering, clamps, unions, or glue required
• Connects copper, PEX, CPVC, or PE-RT pipe in any combination
• Rated to 200 degrees F and 200 psi for potable water and radiant heating service
• 45 degree elbow angle for pipe runs where a 90 degree bend is impractical
• Specially formulated O-ring seal seated on pipe insertion
• No access panel required after installation

Compatibility

Designed for use with 1/2 inch copper, PEX, CPVC, and PE-RT pipe in potable water and radiant heating applications.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and depressurize the line before cutting into any existing pipe run. Ensure pipe ends are cut square, deburred, and clean before insertion — debris or out-of-round cuts can compromise the O-ring seal. Verify insertion depth marks on the pipe to confirm full engagement before restoring pressure.
