An industrial hose is usually the first thing that comes to mind when you think about hydraulic plumbing—and for good reason. Well-engineered industrial hose assemblies offer enhanced durability and customization, making them useful for a wide variety of applications.

Then you have tubing that requires a little more foresight but is a straightforward option if you have the correct bending and flaring tools.

Another option that has popped up recently is weldless, threadless plumbing. This plumbing system is designed using specialized equipment that crimps together different parts of the tubing rapidly.

If you’re unaware of how weldless, threadless plumbing works, explore these FAQs below for details:

How does weldless, threadless plumbing stay connected?

Currently, weldless, threadless plumbing comes in two varieties. The crimping technique uses a connector that has a soft sealing mechanism within the ID. Two pipe heads are brought close together, and the connector is slid over the pipes and placed against the tubes to produce an effective seal.

The flange technique involves sliding a flared neck flange over the pipe end and activating it with a cold forging tool. The combination of these processes results in massive contact pressures that form a seal on the pipe.

What diameter is recommended?

Crimped style plumbing works best with pipes less than 5 inches in diameter because very few manufacturers offer large connectors. The flared joint system can be used in tubing sizes up to 10 inches in diameter. It should be noted that the larger the diameter, the less effective the joint because pressure capacity falls substantially in larger tubes.

What is the pressure rating?

Pressure rating depends on the tube wall thickness, tube diameter, and nature of the system. With smaller bore plumbing, you can find assemblies with 6,000 psi or more.

How does weldless, threadless plumbing fare against industrial hoses?

Threadless, weldless plumbing is easier to set up and often requires fewer safety inspections during installation. However, it has limited applications compared to industrial hoses. Additionally, since the technology is relatively new, it’s also more expensive to install.

If you’re looking for premium-quality industrial hoses assemblies, we offer a wide selection of custom hose products, including corrugated metal hoses, high-pressure PTFE hoses, and industrial hose fittings.
