The BRASSCRAFT 64-4X is a 64 Series compression tee fitting designed for use in plumbing and fluid distribution systems where a reliable branch connection is needed at a 1/4 inch line. Constructed from brass, this tee accepts compression-style connections on all three ports, allowing a technician to split or branch a supply line without soldering. It is a compact, no-flame fitting that suits tight service spaces. Plumbers and service technicians install this type of fitting in water supply, refrigeration drain, and light fluid-handling applications.
The 64-4X is suited for residential and light commercial plumbing installations where 1/4 inch compression connections are standard. Typical applications include ice maker supply lines, reverse osmosis system tubing, and similar small-diameter water or fluid distribution runs. The compression design makes it compatible with soft copper tubing and approved flexible plastic tubing of the corresponding outside diameter. No specialized equipment or open flame is required for installation, which makes it practical for service calls and retrofit work.
Designed as an OEM-style replacement and general-use compression tee fitting for 1/4 inch outside diameter tubing in residential and light commercial plumbing systems.
Installation is performed by a licensed plumber or qualified service technician. Shut off the water supply and relieve line pressure before disassembling any existing connections. Ensure tubing ends are cut cleanly and deburred before seating into the compression fitting to prevent leaks. Follow local plumbing codes, including applicable IPC requirements, for approved tubing materials and fitting use in potable water systems.
