Plug GN 749-M30x1,5-B Z035811

Threaded plug GN 749-M30x1.5-B – reliable sealing in hydraulic systems

The GN 749-M30x1.5-B plug is an element used to seal threaded holes in hydraulic and pneumatic systems. Made of galvanized steel, it provides high corrosion resistance and mechanical strength. This plug, thanks to the use of an FPM (Viton®) rubber seal, is particularly recommended for applications requiring resistance to high temperatures and aggressive media.

Design and materials

The plug is made of galvanized steel grade 5.8, which guarantees a tensile strength of up to 500 N/mm². It is subjected to ultrasonic tests, which confirm the absence of internal defects. A key element is the seal made of synthetic FPM (Viton®) rubber, characterized by exceptional chemical and thermal resistance – up to 180°C. The plug design with a groove for the seal prevents it from shifting during tightening, ensuring stable and reliable sealing.

Application and benefits

The GN 749-M30x1.5-B plug finds wide application in:

• Hydraulic systems: Provides a tight seal for hydraulic lines and components.
• Machines and equipment: Used as a closing element for technological holes.
• Industrial equipment: Ideal for applications requiring resistance to high temperatures and aggressive media.
• Pneumatic systems: Can be used in compressed air systems where high chemical resistance of the seal is required.

Using the GN 749-M30x1.5-B plug translates to:

• High tightness: The Viton® seal guarantees reliable sealing even in difficult conditions.
• Resistance to external factors: Galvanized steel protects against corrosion, and FPM rubber provides chemical and thermal resistance.
• Durability: Made of high-quality materials and precision machining ensure a long product life.
• Safety: Ultrasonic tests confirm the absence of internal defects, which increases safety.
• Easy installation: Standard M30x1.5 thread allows for quick and easy installation of the plug in the appropriate hole.

Remember to choose the appropriate plug depending on the medium and operating temperature of the system!
