The PEX Compression Fitting is mainly composed of three parts: the joint body, the sleeve and the nut.

Introduction

When the sleeve and nut sleeve are inserted into the joint body on the steel pipe and the nut is tightened, the outer side of the front end of the sleeve is fitted to the cone of the joint body, and the inner edge evenly bites into the seamless steel pipe to form an effective seal. It is easy to install and can withstand high pressure, so it is widely used.

Advantage

They are reliable in connection, high in pressure resistance, good in temperature resistance, sealing and repeatability, convenient in installation and maintenance, and safe and reliable in operation.

Working principle

The working principle of the ferrule joint is to insert the steel pipe into the ferrule, lock it with the ferrule nut, touch the ferrule, cut into the pipe and seal it. It does not need to be welded when it is connected with the steel pipe, which is beneficial to fire prevention, explosion prevention and high-altitude operation, and can eliminate the disadvantages caused by inadvertent welding. Therefore, it is a relatively advanced connector in the pipelines of automatic control devices in oil refining, chemical, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. It is suitable for pipeline connection of oil, gas, water and other media.
