Midland Industries FS68041212 Run Tee Hydraulic Adapter

Product Description

The MIDLAND INDUSTRIES FS68041212 is a steel hydraulic run tee adapter designed for use in high-pressure hydraulic plumbing systems. It connects three fluid lines using a combination of Male O-Ring Face Seal (ORFS) and Male Adjustable O-Ring Boss (ORB) end types, providing a leak-resistant inline tee configuration. Connection 1 and Connection 3 are 3/4-inch Male ORFS with a thread size of 1-3/16-12. Connection 2 is a 3/4-inch Male Adjustable O-Ring Boss with a thread size of 1-1/16-12. The center-to-end dimension measures 3.64 inches by 1.47 inches. Licensed hydraulic technicians and fluid power specialists typically install this fitting in mobile equipment, industrial machinery, and hydraulic power units.

This run tee is suited for steel hydraulic tube and hose assemblies operating in environments where reliable sealing and vibration resistance are required. The O-Ring Face Seal connections eliminate the need for thread sealant and provide consistent, metal-to-metal face sealing with O-ring compression, making them a standard choice for high-pressure hydraulic circuits. The adjustable O-Ring Boss port on Connection 2 allows for rotational positioning before the O-ring locknut is tightened, simplifying manifold and block porting alignment during assembly. This fitting is commonly specified in agricultural, construction, and industrial hydraulic systems.

Key Features

• Three-port run tee configuration for inline hydraulic line branching
• Male ORFS connections on ports 1 and 3 with 1-3/16-12 thread for leak-resistant face sealing
• Male Adjustable O-Ring Boss on port 2 with 1-1/16-12 thread for flexible port orientation
• Steel construction for durability in high-pressure hydraulic applications
• Center-to-end dimensions of 3.64 inches by 1.47 inches for compact routing
• No thread sealant required on ORFS connections due to O-ring face sealing design

Compatibility

Designed as an OEM-style steel hydraulic adapter for 3/4-inch ORFS and 3/4-inch Male Adjustable O-Ring Boss hydraulic plumbing systems requiring a run tee configuration.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and drain the hydraulic system completely before removing or installing any fittings. Inspect O-rings for damage before assembly and lubricate them lightly with clean hydraulic fluid prior to connection. Torque all fittings to the hydraulic fitting manufacturer specifications for the thread size and connection type being used.
