Description & Features

Designed for straight bulkhead installations, the Steel Adapter, 11/16-16 Male O-Ring Face Seal To 11/16-16 Male O-Ring Face Seal, Straight Bulkhead is a same-size union fitting from Eaton Aeroquip's FF1994T Series. The O-ring face seal configuration on both ends provides a reliable, leak-resistant connection suited to demanding fluid system environments.

With overall dimensions of 2.09 inches (A) by 1.34 inches (B), this steel adapter is well suited for use across marine and military, chemical processing, pulp and paper, food and beverage processing, and off-shore drilling applications. Its bulkhead design allows installation through panels or bulkheads where a through-passage fitting is required, making it a practical choice for compact or space-constrained assemblies in industrial hydraulic circuits.

Question by: Scott H on Mar 5, 2026, 10:07 AM
got a bulkhead pass-through setup, is this the kind of fitting that goes through a panel and seals up on both sides?
Answer by: Customer Support on Mar 7, 2026, 6:40 AM
For a straight bulkhead install, this adapter is meant to pass through a panel or bulkhead where you need a through-connection. Both ends are 11/16-16 male O-ring face seal, so it mates ORS to ORS on each side for a leak-resistant hookup.
Question by: Shane B on Sep 28, 2025, 5:40 PM
Will this adapter work for a bulkhead fitting on my boat?
