NPTF Pipe 45° Female Elbow (Stainless Steel) - Part 5505-SS

Part Number: 5505-SS

NPTF Pipe 45° Female Elbow (Stainless Steel)

Product Overview

The Delphi Fittings Part 5505-SS is a 45° female pipe elbow designed to connect two male NPT (National Pipe Taper) or NPTF (Dryseal) threaded pipes or fittings at a 45-degree angle. Manufactured from premium stainless steel (typically Grade 316 SS), this elbow offers exceptional resistance to corrosion, chemicals, and extreme temperatures. Its NPTF (Dryseal) threads on both female ends are machined to higher tolerances to create a reliable metal-to-metal seal with male NPTF fittings, making it an excellent choice for demanding applications in marine, chemical processing, food and beverage, and other harsh environments where a durable, corrosion-resistant 45-degree connection is required.

Key Features & Specifications

Material High-Grade Stainless Steel (Typically 316 SS for superior corrosion resistance)
End 1 Configuration Female NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476)
End 2 Configuration Female NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476)
Angle 45 Degrees
Body Style 45° Female Elbow, typically with hex features or flats for wrench engagement.
Galling Warning: Stainless steel threads are prone to galling (cold-welding). Using a thread lubricant or anti-galling paste compatible with stainless steel on the mating male threads is highly recommended to prevent thread damage during assembly.

Commonly Available Sizes (Part #5505-SS Series)

Delphi Fittings offers the 5505-SS Stainless Steel NPTF 45° Female Elbow in a range of common nominal pipe sizes, with both ends typically being the same size.

Examples include (Female NPTF x Female NPTF):

  • 5505-02-SS: 1/8" NPTF x 1/8" NPTF
  • 5505-04-SS: 1/4" NPTF x 1/4" NPTF
  • 5505-06-SS: 3/8" NPTF x 3/8" NPTF
  • 5505-08-SS: 1/2" NPTF x 1/2" NPTF

Applications

The Part 5505-SS Stainless Steel 45° Female Elbow is ideal for:

  • Creating a 45-degree connection between two male NPTF or NPT pipes or fittings in environments where superior corrosion resistance is critical.
  • Use in marine and offshore hydraulic systems, chemical processing plants, food and beverage facilities, pharmaceutical production, and water treatment systems.
  • Applications involving corrosive fluids, high humidity, saltwater spray, or frequent cleaning cycles where carbon steel fittings would degrade.
  • Providing a strong, durable, and leak-resistant 45-degree connection for stainless steel piping systems, offering a smoother flow path than a 90-degree elbow.

Installation & Usage Guidelines

  • Ensure all mating male NPTF threads and the female NPTF threads of the elbow are meticulously clean and free from any damage or contaminants.
  • Thread the male fittings into each end of the elbow by hand until snug.
  • Use appropriate wrenches on the hex body of the elbow and on the mating fittings to tighten securely. Tighten until a leak-proof seal is achieved, but avoid over-tightening.

Why Choose Delphi Fittings Part 5505-SS?

  • Optimized 45° Routing: Provides a robust 45-degree connection for routing NPTF threaded lines around obstructions or for smoother flow paths.
  • Dryseal Performance: NPTF threads provide a robust metal-to-metal seal, minimizing the risk of leaks in critical applications.
  • Wide Chemical & Temperature Compatibility: Stainless steel is suitable for a broader range of fluids and temperatures than carbon steel.
