Komatsu Part TEE 21N-68-32280

—

Product Overview

The 21N-68-32280 TEE is a genuine Komatsu OEM replacement tee fitting. Tees split a single fluid line into two branches — allowing one hose or tube connection to feed two separate circuits, or to combine flows from two sources into one downstream line. They're simple components, but a leaking tee creates the same fluid loss and system contamination risk as any other fitting.

When to Replace

• Threads damaged or stripped on any of the three ports
• Cracked body — especially at the junction where the three branches meet, a stress concentration point
• Any sealing surface scored or pitted — O-ring face, flare seat, or cone
• The hex flats are rounded — proper tightening torque can no longer be applied
• The tee was overtightened during previous installation and shows deformation

Installation

1. Confirm 21N-68-32280 in your parts catalog
2. Clean threads and sealing surfaces on all three ports and the mating components
3. Install new O-rings or seals on every connection point
4. Apply thread sealant only to tapered threads — never to O-ring or flare face connections
5. Tighten to torque while holding the tee in the correct orientation — it must remain aligned with the branch connections
