Quick-Release Push-to-Connect Lubrication Fittings

Modern assembly lines demand speed, and traditional threaded compression fittings can be time-consuming to install. Quick-Release Push-to-Connect Fittings revolutionize the plumbing of low-to-medium pressure oil systems. Designed specifically for use with nylon tubing, the installer simply pushes the cleanly cut tube into the fitting. Internal stainless steel teeth instantly grip the tube, while an O-ring provides a perfect, leak-free seal. To remove, simply press the release collar and pull the tube out.

Key Advantages & Benefits:

  • Rapid Installation: Cuts plumbing assembly time by up to 70% compared to traditional nut-and-ferrule compression fittings.
  • Tool-Free Connection: No wrenches are required to secure the tubing to the fitting.
  • Reusable Design: Tubes can be connected and disconnected multiple times without damaging the fitting or requiring replacement parts.
  • Space Saving: Low-profile design is perfect for tight manifolds and compact machinery spaces.

Versatile Applications:

  • Automated multi-point oiling systems
  • Pneumatic control lines
  • Printing press secondary oil lines
  • Packaging machinery

Frequently Asked Questions (FAQ):

  • Q: Can these be used for high-pressure grease? A: No. Push-in fittings are generally rated for lower pressures (typically up to 15-30 bar) and are suitable for oil or very fluid grease. High-pressure grease will blow the tubing out of the fitting.
  • Q: Why is my push-in fitting leaking? A: The most common cause is a tube that was cut at an angle or has a scratched surface. Cut the tube perfectly straight with a specialized cutter and re-insert it.

FAQ

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation


Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.


Process Validation Before Mass Manufacturing


Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.


Integrated Heating and Degassing Process


The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
