Midland Industries FS68031212 Branch Tee Steel Orfs Orbs

Product Description

The MIDLAND INDUSTRIES FS68031212 is a steel branch tee fitting designed for hydraulic systems requiring a three-port junction in a compact, leak-resistant package. It features two Male O-Ring Face Seal (ORFS) ports and one Male Adjustable O-Ring Boss (ORBS) port, all sized at 3/4 inch. The ORFS connections use a flat sealing face and captive O-ring to achieve a high-integrity, vibration-resistant seal without thread sealant. The adjustable ORBS port allows for precise directional positioning of connected lines. This fitting is installed by hydraulic technicians and fluid-power mechanics working on industrial or mobile hydraulic circuits.

This branch tee is suited for hydraulic plumbing applications where a single supply or return line must be split into two directions, or where three circuit branches converge at one junction. Common installations include mobile equipment hydraulics, industrial power units, and agricultural machinery. The fitting belongs to the FS6803-NWO Series and is categorized under Steel O-Ring Face Seal Adapters. Its center-to-end dimensions of 2.94 inches by 2.67 inches make it practical in tight plumbing runs where space is limited.

Key Features

• Two Male ORFS ports (3/4 inch, 1-3/16-12 thread) provide flat-face sealing for leak-resistant hydraulic connections
• One Male Adjustable ORBS port (3/4 inch, 1-1/16-12 thread) allows directional adjustment of the connected line
• Steel construction for durability and compatibility with high-pressure hydraulic fluid service
• Compact geometry at 2.94 inches by 2.67 inches center to end suits confined installation spaces
• No thread sealant required on ORFS connections, reducing installation variables and contamination risk

Compatibility

Part of the MIDLAND INDUSTRIES FS6803-NWO Series Steel O-Ring Face Seal Adapters. Designed as an OEM-style hydraulic fitting for systems using 3/4 inch Male ORFS and Male Adjustable ORBS port configurations in steel hydraulic plumbing assemblies.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power mechanic. Depressurize and bleed the hydraulic system completely before removing any fittings or opening circuit connections. Inspect the O-ring seals for damage before assembly and replace if necessary - do not reuse compromised seals. Torque all connections per the equipment manufacturer or fitting supplier specifications; do not use pipe thread sealants on ORFS or ORBS connections.
