DELPHI FITTINGS
Part Number: 6805L-SS
SAE ORB Male x NPTF Female 90° Long Elbow (Stainless Steel)
Product Overview
The Delphi Fittings Part 6805L-SS is an extended length 90° elbow adapter, precision-machined from high-grade stainless steel (typically Grade 316 SS). This specialized fitting is 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, particularly in applications where additional reach or clearance is necessary for proper installation or accessibility. 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, with an extended dimension on one or both legs of the elbow. The inherent superior corrosion resistance of stainless steel makes this long elbow an essential component for demanding hydraulic systems in marine environments, chemical processing plants, food and beverage facilities, or pharmaceutical industries.
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) - potentially with extended dimension for reach. |
| End 2 Configuration | Female NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476) - potentially with extended dimension for reach. |
| Angle | 90 Degrees |
| Design Feature | Long pattern design providing extended reach or clearance compared to standard elbows. |
| Body Style | Long Elbow Adapter with hexagonal (hex) features for secure wrench engagement. |
| 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. 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. |
| 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 with extended reach 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 depend on the size of the adapter and the 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. |
Commonly Available Sizes (Part #6805L-SS Series)
Delphi Fittings offers the 6805L-SS Stainless Steel ORB Male to NPTF Female 90° Long Elbow in various common size combinations. Sizes are generally denoted by ORB dash numbers (for the male ORB end) and NPTF nominal pipe sizes (for the female NPTF end).
Examples include (Male ORB x Female NPTF Long):
- 6805L-04-04-SS: -04 (7/16-20 UNF) ORB Male x 1/4" NPTF Female Long
- 6805L-06-06-SS: -06 (9/16-18 UNF) ORB Male x 3/8" NPTF Female Long
- 6805L-08-08-SS: -08 (3/4-16 UNF) ORB Male x 1/2" NPTF Female Long
Note: Each ORB male end includes an appropriate O-ring (Viton® recommended for stainless steel use). The 'L' suffix denotes an extended length on one or both legs of the elbow compared to the standard 6805-SS. It's important to confirm specific dimensions if critical for your application. For unlisted size combinations, specific length requirements, or material grade needs (e.g., 316L), please contact our sales team.
Applications
The Part 6805L-SS Stainless Steel 90° Long Elbow is particularly beneficial for:
- Connecting components with male SAE O-Ring Boss (ORB) ports to male NPTF threaded pipes or fittings at a 90-degree angle, especially where the connection point is recessed, obstructed, or requires additional clearance for tools or adjacent components within a stainless steel system.
- Installations in demanding environments such as marine and offshore platforms, chemical processing plants, food and beverage manufacturing facilities, and pharmaceutical production lines where both superior corrosion resistance and the ability to navigate challenging port locations are essential.
- Use in complex machinery layouts where a standard length 90° elbow (like the 6805-SS) does not provide sufficient reach or clearance for a secure and accessible connection.
- Maintaining material consistency in all-stainless steel hydraulic systems to prevent galvanic corrosion and ensure system longevity and purity.
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 6805L-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 long 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, especially those with extended dimensions, 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.
