A Bunn 42573 3-Way Fitting routes liquid through connected lines to maintain steady flow within the system.
The fitting directs liquid through three connected 1/2-inch lines so the machine can maintain proper routing between internal tubing paths. Its barbed tee design creates a secure hose grip and consistent branch connection, which matters for reducing leaks, preserving flow and supporting reliable operation.
The fitting may need to be replaced if the machine shows reduced liquid flow, uneven distribution or leaking around the connected tubing. Common indicators include cracks, wear at the barbed ends, loosened hose retention or damage from heat, cleaning chemicals or long-term moisture exposure.
