Product Overview
The Delphi Fittings Part 2606 is a specialized run tee adapter designed for hydraulic systems that require branching a male NPTF (National Pipe Taper Fuel / Dryseal) component from a JIC (Joint Industry Council) 37° flare main line. This fitting distinctively features two male JIC 37° flare ends on the run (in-line portion) and one female NPTF pipe thread on the 90-degree branch. This configuration allows for the connection of two female JIC swivel fittings or flared tubes in a continuous run, while providing a female NPTF take-off point for connecting a male NPTF pipe or fitting. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2606 tee ensures robust and leak-free connections in various industrial and mobile applications where mixed fitting types are present.
Key Features & Specifications

Specific Applications & Hydraulic Circuit Routing
Part 2606 fittings provide reliable, high-integrity connections across demanding mobile and stationary fluid power applications:
- Industrial Hydraulic Machinery: High-pressure hydraulic circuits, power packs, and hydraulic manifolds utilizing Part 2606 for reliable fluid conveyance.
- Mobile & Construction Equipment: Excavators, agricultural machinery, and heavy equipment subject to vibration, pressure pulsations, and harsh operating conditions.
- Fluid Routing & Manifold Transition: Facilitates smooth tube-to-hose or port-to-tube connections without imposing residual mechanical stress on hydraulic lines.
Installation & Assembly Guidance
- Surface & Thread Inspection: Ensure all male 37° flare surfaces, mating female cones, and thread flanks are clean, smooth, and free of burrs or contaminants.
- Finger-Tight Alignment: Align the mating connections coaxially and thread the connection by hand until fully seated finger-tight.
- Flats From Finger Tight (F.F.F.T.): Tighten the nut or hex body using the recommended SAE flats-from-finger-tight (FFFT) method or calibrated torque wrench to achieve proper metal-to-metal cone engagement.
- Dual-Wrench Backup Practice: Always support the fitting body hex with a backup wrench while tightening the mating nut or pipe connection to prevent inadvertent loosening.
