Sharkbite U3370LFA 3/4 in Push Fit Slip Tee Lead Free 6-pack

Product Description

The SHARKBITE U3370LFA is a 3/4-inch x 3/4-inch x 3/4-inch lead-free push-fit slip tee designed for fast, tool-free connections in potable and hydronic water distribution systems. Constructed from DZR (dezincification-resistant) brass, this fitting is rated to 200 psi and 200 degrees F, making it suitable for a wide range of residential and light commercial plumbing applications. An integral tube liner is included, enabling compatibility with PEX and CPVC tubing in addition to copper. Licensed plumbers and pipe fitters install this fitting without solder, crimps, or clamps, reducing labor time on both new construction and repair work. This package contains 6 fittings.

The U3370LFA is used in residential and commercial water supply systems where a three-way branch connection is needed on 3/4-inch lines. Its push-fit design makes it well suited for tight spaces or retrofit work where torch access is limited or undesirable. The fitting is certified for underground applications as a manufactured joint and does not require an access panel when buried, which is a meaningful advantage in slab and below-grade installations. Suitable for use with copper tubing (copper tube size), CPVC, and PEX with the included integral tube liner.

Installation Notes

Installation is performed by licensed plumbers or qualified pipe fitters. Shut off the water supply and relieve system pressure before cutting into any existing line.

Verify tubing type and size compatibility before installation, and confirm that the correct tube liner is seated for PEX or CPVC connections.
