Applicable Models of Oil System Parts

Auxiliary Oil Tank Assembly

The model is equipped with a sealed oil tank, and the Auxiliary Oil Tank Assembly can be used as an additional oil storage space for the main oil tank to store a sufficient amount of lubricating oil. Suitable for 8420, 9820 and other models.

8420 Oil Tube Fitting

The 8420 Oil Tube Fitting connects the oil pipe of the bartack machine's lubrication system with the oil tank and oil supply components to realize the sealed connection of the lubricating oil circuit and ensure the stable delivery of machine oil. Suitable for 8420 bartack machines.

8420 Oil Tube Clamp

The 8420 Oil Tube Clamp is used to fix the oil pipe of the bartack machine's lubrication system, avoiding the oil pipe from loosening and bending due to vibration and displacement generated by the high-speed operation of the equipment, ensuring the smoothness of the lubricating oil circuit. Suitable for 8420 bartack machines.

8420 Oil Cap

The 8420 Oil Cap is usually designed with a sealing ring, which can tightly seal the oil filling port of the oil tank. Bartack machines mostly work in workshop environments with more dust such as garment factories. Suitable for 8420 bartack machines.

Oil System Parts: Common Materials of 8420 Oil Tube Fitting

PA6 is a polyamide made from caprolactam, forming long and durable molecular chains that give the material its characteristic strength, toughness, and heat resistance.

Its balance of mechanical performance, processability, and cost efficiency makes it one of the most widely used engineering plastics across multiple industries.

It's strong, reliable, and easy to manufacture — which is why engineers rely on it for such a wide range of applications.

Oil System Parts: Material Advantages of PA6

Strong And Mechanically Reliable

Performs well under load, especially when reinforced with glass fiber, carbon fiber, mineral fillers, or hybrid reinforcements.

Great Toughness

Handles impact and vibration better than many engineering plastics.

Good Heat Resistance

Suitable for under-the-hood and industrial environments.

Excellent Chemical Resistance

Resistant to oils, fuels, coolants, and lubricants.

Highly Customizable

Performance can be tuned with GF, impact modifiers, mineral fillers, or lubricants.

Our Service Advantages

FAQ

Q: What are oil system parts used for in sewing machines?

A: Oil system parts support lubrication storage and oil flow control, helping bartack machines maintain smooth movement and reduce wear during long production cycles.

Q: How do oil system parts affect machine lifespan?

A: Properly designed oil system parts ensure stable oil delivery, reducing friction and heat, which helps extend the service life of critical machine components.

Q: Do oil system parts require regular inspection?

A: Basic checks of oil system parts help detect loose fittings or aging seals early, supporting stable machine operation.

Q: Can oil system parts handle high-speed sewing conditions?

A: Industrial-grade oil system parts are built to remain stable under vibration and continuous high-speed bartack sewing.

Q: How do oil tube clamps support lubrication stability?

A: Oil tube clamps in oil system parts secure oil lines, preventing movement or bending that could interrupt oil flow.

Q: What role does the oil cap play in oil system parts?

A: The oil cap in oil system parts seals the oil tank opening, protecting lubricating oil from dust and debris.

Q: Are oil system parts suitable for bulk spare supply?

A: Yes, oil system parts are commonly stocked as replacement components, making them ideal for long-term wholesale purchasing programs.
