AÂ TEE adaptor with ORFS (M) x ORFS (F) x ORFS (M)Â threads is a high-performance hydraulic fitting designed for leak-free connections in high-pressure systems. Here's a detailed breakdown:
Adaptor - TEE - SAE ORFS (M) x ORFS (F) x ORFS (M)
Thread Type: ORFS (O-Ring Face Seal)
Standard: SAE J1453
Seal Type: O-ring face seal
Thread Form: Straight thread (UN/UNF)
Sealing Mechanism:
Male ORFS: Has a machined flat face with an O-ring seated in a groove.
Female ORFS: Has a flat face that compresses the O-ring on the male fitting to form a leak-proof seal.
Design & Configuration
Shape: T-shaped fitting
Ends:
Two male ORFS ends (typically inline)
One female ORFS branch (perpendicular)
Purpose: Connects three hydraulic lines with ORFS fittings, allowing integration of male and female connections in a single unit.
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 and temperature range. Â
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 properly seated 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.
