Adaptor - TEE - JIC (M) x BSPP (M) x JIC (M)

This is a T-shaped hydraulic fitting that connects three lines:

• Two ends with JIC male threads
• One end with a BSPP male thread

Thread Types Explained

JIC (Joint Industry Council) Male

• 37° flare fitting (SAE J514 / ISO 8434-2 standard)
• Seals via metal-to-metal contact between the flare and a matching female seat
• Common in hydraulic systems, especially in North America
• Sizes range from 1/8" to 2"

BSPP (British Standard Pipe Parallel) Male

• Parallel thread (ISO 228 standard)
• Requires a bonded seal (O-ring) or washer to seal against a flat face
• Common in European and Australian hydraulic and pneumatic systems

Applications

• Hydraulic systems where North American (JIC) and European (BSPP) components need to be integrated
• Industrial machinery, agricultural equipment, mining, and construction
• Fuel delivery, fluid power, and compressed air systems

Materials & Pressure Ratings

• Common materials: 316L stainless steel, carbon steel, brass
• Pressure ratings vary by size and material:
  • Up to 5000 PSI for smaller sizes (e.g., 1/4", 3/8")
  • Lower for larger sizes (e.g., 1", 1-1/4")

Installation Tips

• JIC ends: Tighten until the flare seats firmly; avoid over-tightening to prevent cracking.
• BSPP end: Use a bonded seal washer and torque to spec for a leak-free seal.
• Always check for thread compatibility and sealing method before installation.
