Part Number: 6805-SS

SAE ORB Male x NPTF Female 90° Elbow (Stainless Steel)

Product Overview

The Delphi Fittings Part 6805-SS is a 90° elbow adapter, precision-machined from high-grade stainless steel (typically Grade 316 SS). This fitting is specifically engineered to create a secure, right-angle connection between a male SAE O-Ring Boss (ORB) port and a male NPTF (National Pipe Taper Fuel / Dryseal) threaded pipe or fitting. It features a male SAE O-Ring Boss thread with an O-ring groove on one end, and a female NPTF pipe thread on the other, oriented at 90 degrees to each other. The superior corrosion resistance offered by stainless steel makes this elbow an essential component for demanding applications in environments such as marine, chemical processing, food and beverage production, or pharmaceutical industries, where system integrity, purity, and longevity are critical.

Key Features & Specifications

Material	High-Grade Stainless Steel (Typically 316 SS for optimal corrosion resistance)
End 1 Configuration	Male SAE O-Ring Boss (ORB) (conforming to SAE J1926-1 / ISO 11926-1)
End 2 Configuration	Female NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476)
Angle	90 Degrees
Body Style	Elbow Adapter with hexagonal (hex) features for secure wrench engagement during installation.
Sealing Mechanism	ORB End: Utilizes an elastomeric O-ring (Viton® recommended for stainless steel) which seals effectively against the chamfered boss of the mating female ORB port, providing a high-integrity, leak-proof seal. NPTF End: Designed to seal with a mating male NPTF pipe fitting (Dryseal). If connecting to a standard NPT male fitting, the use of a compatible thread sealant is recommended for an optimal seal.
Corrosion Protection	Inherent to the stainless steel material; typically passivated to enhance surface integrity and corrosion resistance.
Primary Function	To provide a 90-degree, leak-proof connection from a male SAE ORB port to a female NPTF pipe or fitting, offering the enhanced durability and superior corrosion resistance of stainless steel.
Working Pressure	Suitable for high-pressure hydraulic systems. Specific pressure ratings are dependent on the size of the adapter and the particular application conditions.
O-Ring Material (for ORB end)	Viton® (FKM) is strongly recommended for stainless steel applications to ensure compatibility with a wide range of aggressive fluids and extreme temperatures. The O-ring is typically supplied with the fitting.

Applications

The Part 6805-SS Stainless Steel 90° Elbow is essential for:

Connecting components with male SAE O-Ring Boss (ORB) ports (such as pumps, valves, cylinders, or manifolds) to pipes, hoses, or other fittings that are terminated with male NPTF threads, especially in systems requiring the corrosion resistance of stainless steel and a right-angle change in fluid direction.
Interfacing stainless steel ORB-ported equipment with stainless steel NPTF piping systems to maintain material consistency and prevent issues like galvanic corrosion.
Use in demanding environments including marine and offshore installations, chemical processing facilities, food and beverage manufacturing equipment, and pharmaceutical production lines, where exposure to corrosive substances, saltwater, or frequent cleaning protocols is common.
Applications requiring high levels of system purity where the inert nature of stainless steel is advantageous.

Installation & Usage Guidelines

Thoroughly clean all ORB threads, the O-ring groove on the adapter's male ORB end, the female NPTF threads, and all mating surfaces (female ORB port and male NPTF fitting). Ensure they are free from any damage, debris, or contaminants.
Verify that the O-ring material (Viton® is recommended for stainless steel and demanding applications) for the ORB end is correct for the specific system fluid, temperature, and pressure. Ensure the O-ring is correctly lubricated with a system-compatible fluid or an appropriate O-ring lubricant.
Carefully install the lubricated O-ring onto the ORB male end of the 6805-SS elbow, ensuring it is properly and evenly seated in its groove without being twisted, cut, or pinched.
Thread the ORB male end of the elbow into the mating female ORB port by hand. Before fully tightening, orient the elbow to the desired 90-degree angle to ensure correct alignment of the NPTF end for the connecting line.
Once oriented, use a wrench on the elbow's hex body to tighten the ORB connection to the manufacturer's recommended torque specification for that specific ORB size and stainless steel material.
For the female NPTF end of the adapter, thread a mating male NPTF pipe or fitting into it. It is highly recommended to apply a suitable thread sealant (such as PTFE tape or a liquid pipe sealant specifically formulated for use with stainless steel and compatible with the system fluid) to the male NPTF threads. This is particularly important if mating with standard NPT male threads or to ensure an optimal seal in high-pressure NPTF connections. Tighten to the recommended specification for the NPTF connection size.
Always use appropriate backup wrenches on the elbow's hex body and the mating components during the tightening process to prevent distortion or damage. When working with stainless steel fittings, using a thread lubricant or anti-seize compound (compatible with stainless steel) on both the ORB male threads and the mating male NPTF threads is crucial to prevent galling during assembly.
