DELPHI FITTINGS
Part Number: FS304C-SS
SAE ORFS Cap (Stainless Steel)
Product Overview
The Delphi Fittings Part FS304C-SS is a high-quality cap designed to securely seal the end of a male O-Ring Face Seal (ORFS) fitting. It features a female ORFS swivel nut with an integrated, solid flat face that seals against the O-ring of the male fitting. Manufactured from 316-grade stainless steel, this cap provides a robust, leak-proof termination, protecting the hydraulic system from contamination and fluid loss. It is the ideal choice for capping lines in corrosive or sanitary environments where system integrity is crucial.

Applications
The FS304C-SS cap is an essential component for system maintenance, testing, and storage in demanding industries:
- Securely terminating the end of a hydraulic hose or tube that is fitted with a male ORFS end.
- Sealing off unused male ORFS ports on adapters, manifolds, or other components during system modifications or repairs.
- Protecting hydraulic systems from the ingress of dust, moisture, and other environmental contaminants through open lines.
- Shielding the critical threads and flat sealing face of male ORFS fittings from damage during transport or storage.
- Indispensable in marine, chemical, food processing, and pharmaceutical applications.
Installation & Usage Guidelines
- Ensure the O-ring on the male ORFS fitting is clean, lubricated, and undamaged.
- Inspect the internal flat sealing face of the cap to ensure it is clean and free of debris or scratches.
- Thread the female swivel nut of the cap onto the male fitting until it is finger-tight.
- Use one wrench to hold the male fitting or hose assembly stationary and another wrench to tighten the cap to the manufacturer's recommended torque.
