DELPHI FITTINGS
Product Overview
Delphi Fittings Part 5504 is an SAE 130238 90-degree female pipe elbow designed to connect two male NPT or NPTF threaded lines or nipples at a right angle. Hot-forged from structural carbon steel with thick wall geometry, Part 5504 provides high hoop strength to resist internal thread expansion under severe pressure surges. Internal NPTF Dryseal threads on both ports ensure leak-free performance in rigid piping installations.

Specific Applications & Flow Routing
Part 5504 fittings serve critical fluid-routing roles where robust, leak-free performance is essential:
- Rigid Piping Corner Turns: Joining two male pipe lines at 90° corners along factory wall headers.
- Pump Skid Manifolds: Connecting rigid male pipe spools around power-unit frame perimeters.
- Gauge Panel Plumbing: Adapting male instrument stems around right-angle panel bulkheads.
- Pneumatic Ring Mains: Forming rigid 90° corner drops for airline service points.
Installation & Assembly Guidance
- Thread Cleaning: Inspect internal threads and mating male threads for metal burrs.
- Hand Makeup: Hand-thread male pipes into each port 2 to 3 turns to confirm clean engagement.
- Wrench Tightening: Use an open-end or adjustable wrench on body flats, tightening 2 to 3 turns past finger-tight.
- Dual Wrenching: Always use a backup wrench on the elbow body when tightening the second male pipe.
Why Source Part 5504 from Delphi Fittings?
- Heavy Wall Section: Thick forged walls prevent thread dilation under repeated pressure impulses.
- Precision CNC Tapping: Internal threads tapped with L1 and L3 ring-gauged precision tooling.
- Zinc Plating: Trivalent clear plating delivers durable corrosion protection without hazardous chemicals.
- Complete Size Range: Standard production from 1/8" up to 1" NPTF in steel and 316 stainless.
