Steel Adapter, 9/16-18 Male SAE O-Ring Face Seal Run To 9/16-18 Female SAE O-Ring Face Seal Branch, Tee

Description & Features

Configured as a tee fitting, this Steel Adapter, 9/16-18 Male SAE O-Ring Face Seal Run To 9/16-18 Female SAE O-Ring Face Seal Branch, Tee provides a run-and-branch connection point within hydraulic lines using matching 9/16-18 thread sizing on both ports. The male O-ring face seal run port and female O-ring face seal branch port share the same thread specification, making this a symmetrical tee suitable for splitting or combining flow in a single plane.

Manufactured by Om Industrial Products Corp and also catalogued under the Brennan Industries brand, this fitting is constructed from steel and is sized for 0.25 in. OD tubing. The O-ring face seal design minimizes the risk of thread-initiated leakage, a common consideration in high-pressure hydraulic circuits. It fits within the broader O-Ring Face Seal to O-Ring Face Seal Adapters product line and is an appropriate choice for compact tee configurations where leak integrity is a priority.

So this is a tee, but both sides are the same thread size, right? Just making sure before I order.

Answer by: Customer Support on Jan 28, 2026, 5:01 PM

That's correct, this tee adapter has a 9/16-18 thread on both the male run and female branch ports, allowing for a symmetrical connection.
