SAE ORB Male x SAE ORB Female Reducer/Expander - Part 6410

Part Number: 6410

SAE ORB Male x SAE ORB Female Reducer/Expander

Product Overview

The Delphi Fittings Part 6410 is an SAE ORB Male x SAE ORB Female Reducer/Expander adapter. This versatile straight fitting is designed to connect two SAE O-Ring Boss (ORB) components of different thread sizes. It features a male SAE ORB thread on one end and a female SAE ORB port (with internal boss for O-ring sealing) on the other. Depending on the specific configuration, this adapter can function as a reducer (e.g., larger male ORB to smaller female ORB) or an expander (e.g., smaller male ORB to larger female ORB). Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 6410 provides a reliable, leak-proof solution for adapting ORB port sizes in hydraulic systems.

Key Features & Specifications

Specific Applications & Hydraulic Circuit Routing

Part 6410 fittings provide leak-free fluid power conveyance in demanding mobile and stationary equipment circuits:

  • Hydraulic Valve Manifolds & Blocks: Provides zero-clearance, leak-tight port connections on mobile and industrial hydraulic manifold blocks utilizing Part 6410.
  • Pumps, Motors & Cylinders: Connects fluid power lines directly to SAE straight-thread ORB ports on gear pumps, piston motors, and hydraulic cylinders.
  • Thermal Cycling & High Vibration Systems: Elastomeric O-ring maintains full seal integrity where tapered pipe threads might back off or weep under intense machine vibration.

Installation & Assembly Guidance

  • O-Ring Lubrication: Always inspect and lightly lubricate the elastomeric O-ring with clean system hydraulic fluid prior to thread engagement to avoid pinching or tearing.
  • Straight Fitting Engagement: For straight fittings, hand-thread into the port until the hex shoulder bottoms firmly against the spotface, then torque to SAE J1926 specifications.
  • Adjustable Fitting Orientation: For elbows and tees, back off the locknut and washer completely. Thread fitting into port until washer contacts face, then back out counter-clockwise (max 360°) to align, and tighten locknut.
  • Dual Wrench Security: Hold the adapter body firmly with a backup wrench while securing mating hose swivel nuts or tube connections.

Why Source Part 6410 from Delphi Fittings?

  • SAE J1926 & ISO 11926 Compliance: Precision CNC machined with precise O-ring retaining undercuts to ensure complete interchangeability with North American and European hydraulic equipment.
  • ASTM B117 Superior Corrosion Resistance: Heavy trivalent zinc clear finish delivers exceptional protection against white and red rust in demanding outdoor and mobile environments.
  • 100% Optical Thread Verification: All male and female threads undergo strict go/no-go optical gauge inspection to guarantee flawless field threading without binding.
  • Factory-Direct OEM & Distributor Programs: Manufactured directly at our ISO 9001:2015 certified facility in Yuhuan, China, backed by mill test reports (MTR) and volume distributor pricing.
