product description:

The steel single tube joint is a new and reliable pipe connector widely popularized at home and abroad. It does not need welding when connecting with the steel pipe, and the pipeline installation is extremely convenient. Good sealing and repeatability. This series of pipe joints is a connection method in measurement, hydraulic and pneumatic signal pipelines, and is given priority in engineering design.

working principle:

The steel single tube fitting consists of three parts: the fitting body, the nut and the ferrule. The ferrule is a metal ring with a tapered surface on the outside of the front and rear ends, and a cutting edge on the inside of the front end. The radial shrinkage of the front part of the sleeve changes, and the middle part has a slightly arched protrusion. Continue to rotate the nut to force the cutting edge to cut into the steel pipe, thus realizing the sealing and tightening effect between the steel pipes of the joint body.
