Tee, Straight-Thread, #6, O-Ring
Freightliner

A straight-thread three way branch with O rings built for higher pressure environments and compact routing. All three ends use 9/16-18 threads and the zinc chromate black finish provides corrosion resistance in engine bays and underframes where road salt and oil exposure are routine. The O ring seals enhance leak protection in vibrational and thermal cycling conditions, enabling reliable performance when lines are pressed into tight spaces or subjected to frequent disconnections for maintenance. This fitting supports small bore lines and hoses in cooling, fuel, or lubrication systems while maintaining a low profile that reduces interference with nearby components. Its robust construction helps sustain long service life in demanding fleets, contributing to fewer downtime events due to leaks or fittings failure. Source One Parts Center.
