Product Description:
Product categories: NL Series: Standard Compression Fitting NutsNS series: Thickened or special specification ferrule nuts
A ferrule nut is a specialized fastener used in hydraulic and pneumatic pipelines. It is used in conjunction with a ferrule tube (ferrule), and tightening the nut generates a clamping force that causes the ferrule to engage with the outer wall of the steel pipe, thereby achieving a high-pressure sealed connection.

Features and advantages
Leakage prevention
The tight fit between the ferrule and the pipeline forms a reliable sealing structure, effectively preventing fluid leakage.
High pressure resistance
Suitable for high-pressure hydraulic systems, with stable sealing performance.
High temperature resistance
The stainless steel material can maintain the connection strength under high temperature conditions.
Easy installation
No welding is required; simply tighten with a wrench to complete the pipe connection.

Material
316 stainless steel
suitable for highly corrosive environments such as seawater and chemical plants.
304 stainless steel
suitable for general corrosive environments and food-grade requirements.
35# steel / 45# steel
carbon steel material, suitable for hydraulic systems with high pressure and high strength requirements, and the surface can be galvanized.
Appearance
Surface treatment
Stainless steel is its natural color, while carbon steel is usually galvanized (blue-white or yellow zinc).
Shape
It has a hexagonal shape, making it easy to operate with a wrench, and its surface is smooth and burr-free.
Design
The design features a precision internal conical surface, which ensures even pressure application when mated with the tubing. High thread precision guarantees a smooth tightening process and reliable sealing.

Quality control
Production process: Raw material inspection → Precision cold heading/machining → Threading → Deburring → Surface treatment → Inspection → Cleaning and packaging.
Key batches for quality control undergo hardness and tensile strength testing.
Quality commitment includes material certification
