Adaptor - TEE - SAE Specification - JIC (M) x JIC (M) x BSPT (M)

A TEE adaptor with JIC (M) x JIC (M) x BSPT (M) threads is a hybrid hydraulic fitting designed to connect two SAE JIC male lines with one British Standard Pipe Taper (BSPT) male line. 

Adaptor - TEE - SAE JIC (M) x JIC (M) x BSPT (M)

Thread Types

• JIC (Joint Industry Council) Male:

  • Standard: SAE J514 / ISO 8434-2
  • Thread Form: UNF (Unified National Fine)
  • Seal Type: 37° flare metal-to-metal seal
  • Common Sizes: 1/4", 3/8", 1/2", etc.

• BSPT (British Standard Pipe Taper) Male:

  • Standard: ISO 7-1 / BS 21
  • Thread Form: Tapered
  • Seal Type: Thread interference (requires PTFE tape or thread sealant)
  • Common Sizes: 1/8", 1/4", 3/8", 1/2", etc.

Design & Configuration

• Shape: T-shaped fitting
• Ends:
  • Two JIC male ends (typically inline)
  • One BSPT male branch (perpendicular)
• Purpose: Integrates systems using SAE JIC and British BSPT standards

Materials

• Commonly made from:
  • 316L stainless steel (for corrosion resistance 
  • Carbon steel (zinc-plated)
  • Brass (for lower pressure or non-corrosive systems)

Applications

• Hydraulic systems in industrial, mining, and agricultural equipment
• Fuel and oil lines
• High-pressure fluid transfer
• Cross-standard integration (e.g. North American and British systems)

Installation Tips

• JIC ends: Do not use sealant; ensure clean flare contact and torque to spec.
• BSPT end: Use PTFE tape or thread sealant; do not over-tighten to avoid thread damage.
• Always verify thread compatibility and pressure ratings.
