Adaptor - TEE - SAE Specification - ORFS (M) x ORFS (M) x ORFS (M)

A TEE adaptor with ORFS (M) x ORFS (M) x ORFS (M) configuration is a robust hydraulic fitting designed for high-pressure, leak-free applications. All three ends use SAE J1453-compliant O-Ring Face Seal (ORFS) male threads, making it ideal for systems requiring strong, vibration-resistant connections.

Adaptor - TEE - SAE ORFS (M) x ORFS (M) x ORFS (M)

Thread Type: ORFS (O-Ring Face Seal) Male

• Standard: SAE J1453
• Thread Form: Straight UN/UNF threads
• Seal Type: O-ring face seal
  • Male ORFS fittings have a flat face with an O-ring seated in a groove.
  • Seals against a flat face on a female ORFS fitting.

Design & Configuration

• Shape: T-shaped fitting
• Ends:
  • All three ends are male ORFS
  • Typically, two inline and one perpendicular
• Purpose: Used to split or combine fluid flow in systems using ORFS connections

Materials

• Carbon steel (zinc-plated) – standard for industrial use
• 316 stainless steel – for corrosive or sanitary environments
• Brass – for lower pressure or non-corrosive systems
• O-Ring Materials: Typically Buna-N (NBR) or Viton (FKM) depending on fluid compatibility

Applications

• Hydraulic systems in:
  • Construction and agricultural machinery
  • Industrial automation
  • Marine and aerospace
• High-pressure fluid transfer
• Vibration-prone environments where leak resistance is critical

Installation Tips

• Ensure the O-ring is clean, seated properly, and undamaged.
• Do not use thread sealant—the seal is made at the face, not the threads.
• Tighten to manufacturer-recommended torque to ensure proper compression of the O-ring.
