FAQ Fitting

Question: Why are they called "one-touch" Fitting?: Answer: "One-touch" fittings, often referred to as "push-to-connect" fittings or "quick-connect" fittings, are called so because they are designed for easy and quick installation. The name "one-touch" reflects the simplicity of the fitting process – you can connect tubing or pipes to these fittings with just one simple action, typically pushing the tubing or pipe into the fitting until it locks in place. There's no need for additional tools, clamps, or complicated procedures.
Question: How do one-touch fitting ensure a secure connection?: Answer: One-touch fittings ensure a secure connection through a combination of design features. These features typically include:
1.Push-to-Connect Mechanism: One-touch fittings have a mechanism that allows you to push the tubing into the coupling. This mechanism engages internal components to create a secure seal and connection.
2.Locking Mechanism: Inside the fittings, there are components that lock the tubing in place once it's pushed in. This prevents accidental disconnections due to vibrations or movement.
3.O-Rings or Seals: One-touch fittings often incorporate O-rings or other sealing mechanisms. These seals prevent air leakage and ensure that the connection remains airtight.
4.Release Ring: When you want to disconnect just pushing this ring, you disengage the locking mechanism, allowing you to easily remove the tubing.
Question: Why are fitting so crucial in machinery operations?: Answer: Pneumatic fittingห are essential in machinery because they facilitate quick and dependable connections between pneumatic components, enabling efficient operation, easy maintenance, and flexible system adjustments.
Question: What are the major types of fitting?: Answer: The Air fitting has various shapes and materials but can be divided into 2 major types:
1. ‘The quick connect fitting’ is 2 pieces connector. A ‘Female quick connect fitting’ is connected to the machine to receive or deliver air. And another one is the ‘Male quick connect fitting’ which is used to join the female quick connect fitting and the air hose. by using the tube that has a raceway at the end to lock with the locking ball inside the female quick connect fitting.
2. ‘One-Touch Fitting’ is the type of Fitting that is used to connect an air hose to another one to make it longer, reduce the size of the air hose or separate it from other machines.
Question: What is the significance of synthetic rubber in flexible fitting?: Answer: When compared to other fluids, Air has a small molecule that makes it able to leak out of the pneumatic system. Even a very small gap. So, the synthetic rubber inside the flexible fittings is used to seal those gaps to prevent air leakage. And make the pneumatic system work efficiently.
Question: Can fitting impact energy efficiency?: Answer: Of course, But in order to do that, the choosing of One-touch fittings is important. Because the proper fitting can help prevent air leakage. So the pneumatic system will be able to work efficiently. It also helps to reduce the workload of the air compressor pump as it relates to electricity consumption.
