Ask A Question

Description & Features

Manufactured by Eaton Aeroquip, this steel tee adapter features 3/8-18 NPTF internal pipe threads on all three ports, making it well suited for grease, instrumentation, and general hydraulic system connections. The 2090 Series Steel Adapter, 3/8-18 Female NPT Tee provides a reliable branch connection point where a single line must be split into two parallel paths using standard tapered pipe thread fittings.

With an A dimension of 1.02 inches and full steel construction, this fitting is built for the demands of industrial fluid power applications. The NPTF thread form provides a pressure-tight mechanical seal without requiring additional sealant, though thread sealant is commonly used in practice.

Question by: Diane K on Sep 10, 2025, 2:59 PM
Will this tee fitting hold up okay in a standard hydraulic setup?
Answer by: Customer Support on Sep 12, 2025, 11:49 AM
This Eaton Aeroquip adapter is suitable for most hydraulic systems, along with grease and instrumentation applications.
Question by: Stan J on Mar 14, 2026, 1:19 PM
what all is this tee adapter rated for? grease lines, hydraulic, or just one or the other?
Answer by: Customer Support on Mar 16, 2026, 6:41 AM
Grease, instrumentation lines, and most hydraulic systems all fall within the intended application range for this adapter. It covers a pretty broad range of uses, which makes it handy when you're not running a single dedicated system type.
Question by: Jean J on Nov 29, 2025, 9:20 PM
trying to split one 3/8 npt line into two, is this the right tee for that?
Answer by: Customer Support on Dec 1, 2025, 1:08 PM
For splitting a line, it’s a tee adapter with female NPTF threads on the ports, so it’s meant to join NPTF male pipe ends in a T arrangement.
