DELPHI FITTINGS
Product Overview
Delphi Fittings Part 1504 is a forged carbon steel 45-degree elbow featuring internal threads on both connections. Port 1 is an internal female NPTF Dryseal tapered pipe thread, while Port 2 is an integrated female NPSM straight-thread pipe swivel nut with an internal 30° cone seat. Part 1504 allows a 45-degree angular redirection from existing male-threaded piping without requiring full pipe disassembly, offering a stress-free transition into flexible hose lines.

Specific Applications & Hydraulic Circuit Routing
Part 1504 fittings provide essential non-twisting fluid connections in demanding industrial and mobile power systems:
- Rigid Pipe Drop Realignment: Redirecting vertical male pipe runs 45° toward mobile machine hydraulic reservoirs.
- Bulkhead Angle Clearance: Creating angled breakout points on hydraulic consoles where space limits straight hose entry.
- Cooler & Radiator Connections: Interfacing male heat exchanger ports with flexible rubber lines without tight bends.
- Stationary Plant Hydraulics: Connecting stationary fluid manifold lines to oscillating equipment cylinders.
Installation & Assembly Guidance
- Visual Inspection: Ensure all internal threads and the internal 30° cone face are free of foreign debris.
- Port 1 Makeup: Thread male mating pipe fitting into Port 1 female NPTF port using sealant; tighten securely.
- Port 2 Alignment: Align the mating male hydraulic hose fitting into the female NPSM swivel port.
- Nut Tightening: Hold the forged body with a backup wrench and tighten the swivel nut until the 30° cone firmly seals.
Why Source Part 1504 from Delphi Fittings?
- Precision Machined Seat Geometry: Concentric 30° seat turning ensures positive sealing without excessive tightening torque.
- Heavy-Duty Forged Steel: Forged body withstands continuous dynamic vibration and hydraulic pulsation.
- Zero Hose Torsion: Independent swivel nut rotation eliminates hose carcass twisting during assembly.
- OEM Export Packing: Each part is packaged with thread protectors in heavy corrugated boxes for global logistics.
