316L Stainless Steel Precision CNC Machined Female Threaded Connector

1. Product Overview

This product is a precision CNC-machined female threaded pipe fitting made from a single piece of 316L stainless steel bar stock. It offers excellent corrosion resistance, high structural strength, and long-term stability, making it ideal for demanding applications such as oil & gas pipelines, chemical processing systems, hydraulic equipment, water treatment, and high-pressure fluid transfer systems.

As shown in the images, the surface features a uniform, fine-machined finish with a clean metallic luster. Bulk parts are packed with protective cushioning to prevent scratches and impact damage during transportation.

2. Key Structural Features

✔ Precision NPT Female Thread

• One end machined with NPT 1-1/2 tapered female thread

• Each thread is inspected using go/no-go plug gauges

• Accurate thread profile and taper ensure reliable high-pressure sealing

• Suitable for critical sealing pipeline systems

✔ Multi-Groove Outer Diameter Design

• Multiple circumferential machined grooves on the outer body (as shown in images)

• Used for positioning, anti-rotation, and sealing element placement

• Improves concentricity and assembly stability

✔ Stepped Ends with Chamfered Edges

• Double-end stepped structure for precise alignment and assembly

• All edges chamfered and deburred to prevent seal damage

• Smooth internal bore ensures efficient fluid flow

✔ Wrench Flats for Easy Installation

• Symmetrical machined flat surfaces on the outer body

• Enables easy tightening and disassembly using standard tools

• Prevents slipping during installation, improving field efficiency
