Part Number: FS2408

SAE ORFS Plug

Product Overview

The Delphi Fittings Part FS2408 is an SAE O-Ring Face Seal (ORFS) Plug. This fitting is designed to securely seal an unused female ORFS swivel fitting or port, effectively preventing leakage and protecting the hydraulic system from contamination. It features a male ORFS connection with the characteristic flat face and an O-ring groove that houses the sealing O-ring. The FS2408 plug is typically manufactured with an external hex head for easy installation and removal with a standard wrench. Made from high-quality carbon steel and zinc-plated for corrosion resistance, this ORFS plug is built to SAE J1453 / ISO 8434-3 standards, ensuring reliable performance in high-pressure hydraulic applications.

Key Features & Specifications

Material	High-Grade Carbon Steel
Configuration	Male SAE O-Ring Face Seal (ORFS) Plug (conforming to SAE J1453 / ISO 8434-3)
Head Style	External Hexagonal (Hex) Head for wrench tightening.
Sealing Mechanism	Utilizes an elastomeric O-ring (seated in the groove on the plug's flat face) which compresses against the flat face of the mating female ORFS swivel fitting or port, creating a high-integrity static face seal.
Corrosion Protection	Standard Zinc Plating for enhanced durability and resistance to environmental corrosion.
Primary Function	To securely seal and close off unused female SAE O-Ring Face Seal (ORFS) ports or fittings in hydraulic systems, preventing fluid leakage and ingress of contaminants.
Working Pressure	Designed to safely withstand the pressure ratings of the corresponding female ORFS ports, often suitable for pressures up to 6000 PSI or higher depending on size.
O-Ring Material	Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request for specific fluid or temperature compatibility. The O-ring is supplied with the plug.

Applications

The Part FS2408 SAE ORFS Plug is essential for:

Securely sealing unused female O-Ring Face Seal ports on hydraulic components such as manifolds, valves, pumps, cylinders, and filter housings.
Temporarily or permanently capping off hydraulic lines or hoses that are terminated with female ORFS swivel fittings during system maintenance, modification, storage, or when certain circuits are not in use.
Preventing fluid leakage from open ports and protecting the internal components of high-pressure hydraulic systems from contamination by dust, dirt, and moisture.
Use across diverse industries including mobile equipment (construction, agriculture), industrial machinery, manufacturing plants, and any fluid power application where ORFS connections are utilized for their superior sealing.

Installation & Usage Guidelines

Ensure the female ORFS port or fitting to be sealed and the Part FS2408 plug (including its threads, O-ring groove, and O-ring) are meticulously clean, undamaged, and entirely free from any contaminants or debris.
Verify that the O-ring supplied with the plug is the correct size and material (e.g., Buna-N, Viton®) for the application's fluid, temperature, and pressure. Ensure the O-ring is correctly lubricated with a system-compatible fluid or an appropriate O-ring lubricant.
Carefully install the lubricated O-ring into the groove on the plug's flat face, ensuring it is properly and evenly seated without being twisted, cut, or pinched.
Thread the ORFS plug into the female ORFS port or fitting by hand until the O-ring makes contact with the mating flat face.
Use an appropriately sized wrench on the external hex head of the plug to tighten it to the manufacturer's recommended torque specification for the specific ORFS size. This ensures correct O-ring compression and a secure, leak-proof seal.
After system pressurization, check the plugged port for any signs of leakage.
