47604405001 Elbow Fitting 90 Degree Union for Rotary Screw Air Compressor

Detailed Product Description

Routing Efficiency & Sealed Connection

Unlike straight fittings that force linear alignment, this elbow union creates an efficient 90-degree turn in the pipeline. The male end features a built-in green O-ring (face-seal) that compresses against the port to prevent air or oil leaks, while the female nut provides a reliable mating connection. This combination allows for slight angular adjustment during installation, reducing torque stress on the compressor’s internal manifolds and extending the life of connected hoses.

Key Benefits

• Leak-Proof Seal: O-ring face seal design resists high-pressure air and oil permeation.
• Space Optimization: 90-degree geometry navigates tight compressor enclosures effortlessly.
• Vibration Resistance: Metal-to-metal threading with swivel nut absorbs operational movement.
• Fluid Versatility: Suitable for compressed air, lubricant oil, and separator lines.
• Also Called: elbow fitting, 90 degree fitting, union elbow, compression elbow, pneumatic elbow, air compressor pipe fitting.

Common Applications

• Rotary screw air compressor air discharge and intake routing
• Lubrication oil line connections and separator tank plumbing
• Industrial compressed air system retrofits and skid assemblies
• Compressor maintenance, hose replacement, and spare-parts inventory

When To Replace

Swap out the fitting if the green O-ring hardens, cracks, or flattens causing visible leaks (oil mist or air hissing). Thread stripping, external corrosion, or physical deformation from impact also necessitate replacement. Frequent vibration loosening at the joint often traces back to a worn seal or damaged elbow body.

Installation & Order Note

• Verify thread size, O-ring diameter, and female nut specifications against the original part.
• Isolate power, relieve system pressure, and drain relevant lines before disassembly.
• Do not over-tighten; the O-ring seals by face contact, not by deep thread biting.
• Inspect adjacent hoses for abrasion; route carefully to avoid kinking post-installation.
• Confirm part 47604405001 (D53) matches your machine’s plumbing layout via the old label.
