Blackened Hex Socket Oil Plug

Product introduction

The blackened hexagonal oil plug is a key seal widely used in the lubrication system of mechanical equipment. Its core design combines functionality, durability and convenience. The main body of the product is made of high-quality steel and undergoes precise machining to ensure thread accuracy and consistency, thereby achieving excellent sealing effects and effectively preventing lubricant leakage. The "blackening" treatment on the surface is a common anti-rust process. By generating a dense ferric oxide film on the surface, it significantly improves the corrosion resistance and wear resistance of the product, and can bring a beautiful black matte appearance. The oil plug adopts an internal hexagonal (Allen key) drive design, which has a compact structure and can withstand greater tightening torque. It is very convenient to install and remove, and is especially suitable for installation locations with limited space. To sum up, with its reliable sealing performance, excellent anti-rust ability and convenient installation method, this black hexagonal oil plug has become an ideal choice for oil drain and oil filling holes in various equipment such as gearboxes, engines, reduction boxes, etc. It is a high-quality accessory to ensure long-term stable operation of equipment.

 

Product features

1. Excellent rust and corrosion resistance

The surface of the product has been professionally "blackened" to form a dense and stable protective film of ferric oxide. This film can effectively isolate water vapor and corrosive substances, significantly improve the anti-rust ability and corrosion resistance of the product, and extend the service life under harsh working conditions.

 

2. Reliable sealing performance

Precision-machined from high-quality steel, with precise thread dimensions, and combined with standard sealing washers (such as copper washers or rubber rings), it can achieve excellent sealing effects, effectively prevent the leakage of lubricating oil and grease, and block the intrusion of external impurities.

 

3. Convenient installation and disassembly

The internal hexagonal (Allen key) drive design has a compact structure, which allows the wrench to receive even force and can withstand large tightening torques. At the same time, this design is not easy to slip and requires little installation space. It is especially suitable for operation in narrow or grooved locations and is easy and quick to maintain.

 

4. Durable, economical and practical

The core material has good mechanical strength to ensure that the oil plug body is not easily damaged. The blackening treatment process is mature and cost-effective. It provides sufficient protection while maintaining a high cost performance, making it an ideal choice for industrial equipment.

 

Product application

1. Vehicles and Transportation

Automotive industry: Widely used in oil drain holes and oil filling holes in engine oil pans, gearboxes, differentials, transfer cases, etc. Motorcycles: Lubricating systems for engines and gearboxes. Engineering machinery: gearboxes, hydraulic tanks, axle housings and other parts of heavy-duty trucks, excavators, loaders and other equipment.

 

2. Industrial transmission equipment

Reducer/Gearbox: It is the standard configuration of oil filling and oil drain ports for various types of reducers (such as cycloid reducers, gear reducers). Machine tool equipment: Used in spindle boxes, slides, hydraulic systems and other parts that require lubrication or oil replacement.

 

3. Other general industrial fields

Water pumps and compressors: used for sealing the lubrication chamber. Electrical equipment: such as gearboxes for wind turbines. Agricultural machinery: transmission systems for tractors, harvesters, etc.

 

FAQ

Q: What is the function of the "blackening" treatment of this oil plug?

A: "Blackening" is a surface treatment process that generates a dense layer of ferric iron oxide film on the surface of steel. Its main function is to prevent rust and corrosion. It can also improve the aesthetics of the product and have a certain degree of wear resistance.

 

Q: Do I need to use gaskets during installation?

A: Highly recommended. Usually it needs to be used with sealing gaskets (such as copper gaskets, aluminum gaskets or rubber O-rings). Gaskets fill the tiny gap between the threads and the mounting surface, creating a resilient seal that is key to preventing leaks. Reusing an old gasket may result in a loose seal.

 

Q: Can this oil plug be reused?

A: The oil plug body can be reused if the threads are intact and not damaged. However, it is strongly recommended to replace the sealing gasket with a new one every time to ensure the best sealing effect.
