What are the types and models of hydraulic plugs to choose from

There are a wide variety of types and models of hydraulic plugs to meet the needs of different hydraulic systems and application scenarios. The following are some common types and models of hydraulic plugs:
Material classification:
Plastic plugs: This type of plug is widely used in low-pressure hydraulic systems and is usually made of polypropylene (PP) or polyurethane (PU) materials. They are lightweight, corrosion-resistant, and cost-effective.
Metal plugs: including stainless steel plugs, copper plugs, aluminum plugs, etc. Metal plugs have high strength and pressure resistance, making them suitable for high-pressure and high-temperature environments.
Alloy plugs: such as nickel based alloy plugs, they have excellent corrosion resistance and high temperature resistance, especially suitable for harsh working environments.
Structural classification:
Internal thread plug: suitable for connecting pipes or equipment with internal threads, achieving sealing through threaded connections.
External thread plug: suitable for connecting pipes or equipment with external threads, and also achieves sealing through threaded connections.
Flange plug: used to connect pipes between two flat flanges, sealed by bolts and flange gaskets.
Specification and model:
Common specifications include M5 M6, M8, M10, M12, etc. These specifications indicate the diameter size of the plug.
In addition, there are some special specifications of plugs, such as G1/8 G1/4, G3/8, G1/2, G3/4, etc. are determined based on the size of the connection port of the pipeline or equipment.
Special type:
Magnetic plug: This type of plug is equipped with a magnet inside, which can adsorb ferromagnetic impurities in the pipeline, playing a role in filtering and protecting the system.
Hydraulic magnetic plug: Combining the functions of hydraulic and magnetic, it not only has a sealing effect, but also controls the flow of liquid through a magnetic field.
When selecting hydraulic plugs, it is necessary to comprehensively consider factors such as specific hydraulic system requirements, working environment, pipeline or equipment connection size, etc. It is recommended to consult a professional hydraulic engineer or supplier for more accurate advice and choices.
