DIN 3402 is the German standard for semicircular-head grease fittings. Grease fittings are devices for the supply of oil or other fluid to machine parts for lubrication or cooling. Grease nipples come in various shapes and head sizes, and DIN 3402 describes the technical characteristics of semicircular head grease nipples.
Semicircular-head grease fittings have a semicircular shape at one end, which allows them to be inserted conveniently into a bore that is shaped like a semicircle or semicircular plane. The head has a threaded portion for connection to the oil pipeline that supplies lubricant to the machine.
Materials for the manufacture of DIN 3402 grease nipples
The DIN 3402 grease fittings are made of steel that is additionally coated with zinc. Zinc (Plated) protects against corrosion if the fastener is to be used in aggressive environments.
Areas of application for DIN 3402 grease fittings
Grease fittings with a semicircular head according to DIN 3402 can be used in various fields of technology and industry where it is necessary to ensure the supply of grease or other liquids to machine parts. The main areas of application for semicircular grease fittings are as follows:
- Automotive: semicircular head grease nipples are used in automotive engine lubrication systems to ensure accurate and efficient lubrication of various engine parts.
- Mechanical engineering: semicircular head grease nipples are used in various mechanisms and machine parts that require lubrication or cooling.
- Energy: semicircular head grease nipples are used in the hydropower and wind power industries to lubricate various parts and mechanisms.
