NPTF Pipe 45° Male Elbow (Stainless Steel) - Part 5501-SS

Part Number: 5501-SS

NPTF Pipe 45° Male Elbow (Stainless Steel)

Product Overview

The Delphi Fittings Part 5501-SS is a 45° male pipe elbow designed to connect two female NPT (National Pipe Taper) or NPTF (Dryseal) threaded ports 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 male ends are machined to higher tolerances to create a reliable metal-to-metal seal with female NPTF ports, 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 Male NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476)
End 2 Configuration Male NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476)
Angle 45 Degrees
Body Style 45° Male Elbow, typically with hex features for wrench tightening.
Galling Warning: Stainless steel threads are prone to galling (cold-welding). Using a thread lubricant or anti-galling paste compatible with stainless steel is highly recommended to prevent thread damage during assembly.

Commonly Available Sizes (Part #5501-SS Series)

Delphi Fittings offers the 5501-SS Stainless Steel NPTF 45° Male Elbow in a range of common nominal pipe sizes, with both ends typically being the same size.

Examples include (Male NPTF x Male NPTF):

  • 5501-02-SS: 1/8" NPTF x 1/8" NPTF
  • 5501-04-SS: 1/4" NPTF x 1/4" NPTF
  • 5501-06-SS: 3/8" NPTF x 3/8" NPTF
  • 5501-08-SS: 1/2" NPTF x 1/2" NPTF
  • 5501-12-SS: 3/4" NPTF x 3/4" NPTF

Note: For unlisted sizes, different stainless steel grades (e.g., 304), or other custom requirements, please contact our sales team.

Applications

The Part 5501-SS Stainless Steel 45° Male Elbow is ideal for:

  • Creating a 45-degree connection between two female NPTF or NPT ports 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, often allowing for smoother flow than a 90-degree elbow.

Installation & Usage Guidelines

  • Ensure all mating female NPTF threads and the male NPTF threads of the elbow are meticulously clean and free from any damage or contaminants.
  • While NPTF threads are designed for a dry seal, it is highly recommended to apply a thread lubricant or anti-galling paste suitable for stainless steel to both male threads. If mating with standard NPT female ports, a compatible sealant (like PTFE tape) is also required.
  • Thread one end of the elbow into the first female port by hand until snug.
  • Use appropriate wrenches on the hex body of the elbow and on the mating components to tighten securely. Tighten until the elbow is correctly oriented and a leak-proof seal is achieved, but avoid over-tightening.

Why Choose Delphi Fittings Part 5501-SS?

  • Superior Corrosion Resistance: Manufactured from high-grade stainless steel (typically 316 SS), offering maximum durability in harsh chemical, marine, or sanitary environments.
  • 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.
  • Durable Construction: The solid one-piece design ensures high mechanical strength and integrity.
  • Wide Chemical & Temperature Compatibility: Stainless steel is suitable for a broader range of fluids and temperatures than carbon steel.
  • Standard Compliance: Conforms to ANSI B1.20.3 / SAE J476 standards.
  • Quality-Assured Manufacturing: Produced under Delphi Fittings' rigorous ISO 9001:2015 certified quality management system.
