POL（BOTTLED GAS） Manufacturers

POL connectors are mainly used in LPG systems to connect gas cylinders, regulators, barbecues, fryers and other equipment. They are usually made of high-quality brass or copper alloy materials, with strong corrosion resistance, high temperature resistance and excellent mechanical properties. The main function of POL connectors is to connect gas cylinders and gas equipment through threads to ensure that the gas can be safely and stably delivered to the target equipment. The common design of POL connectors is that they have different types of threads on both ends. The male head is usually an external thread that can be connected to the female head or connector, while the female head is usually used to connect to the gas cylinder. When designing POL connectors, it will ensure that they have excellent sealing performance. Usually, O-rings or other sealing devices are installed inside the connector to prevent gas leakage and ensure the safety of the system. Since LPG systems are often exposed to outdoor environments, especially when barbecues or camping in the open air, the high temperature resistance and corrosion resistance of POL connectors are particularly important. High-quality brass or copper alloy materials can ensure that the connector will not lose stability due to corrosion even in high temperature or humid environments.

Most POL connectors are made of high-quality brass or copper alloy materials, which have excellent physical and chemical properties and can effectively resist corrosion from gases and the external environment. Brass materials have excellent corrosion resistance and can effectively prevent erosion by LPG and external moisture, salt and other substances. Even in marine or humid environments, POL connectors can maintain their structural integrity and extend their service life. And they have good high temperature resistance and can work stably under high temperature conditions. Especially during the combustion of LPG, the connectors need to withstand high temperatures, and brass can ensure that the connectors still maintain good mechanical properties under such conditions. High-quality brass is also very resistant to pressure and can withstand the high pressure that may occur in the LPG system. At the same time, its good sealing performance effectively avoids gas leakage and ensures safety during use.

As a professional Chinese POL connector manufacturer, Legines Industrial Machinery Inc. is equipped with complete production equipment and has strong production capacity. The company's annual production capacity reaches 2.5 million sets, which can meet the needs of large-scale production. Legines produces a variety of POL connectors, including BRASS POL MALE THREAD NUT 2001, PROPANE LP TANK POL SERVICE VALVE 2005, and BRASS FEMALE POL CAP 2004.

BRASS POL MALE THREAD NUT 2001 is an adapter that is mainly used to convert POL female connectors to 1/4-inch male threaded pipe fittings. It has excellent corrosion resistance and high temperature resistance, ensuring long-term use in harsh environments. Its simple design makes it easy to install and provide long-lasting durability. It is suitable for various LPG systems, including connections for RVs, barbecues, fish cookers and other equipment.

PROPANE LP TANK POL SERVICE VALVE 2005 adapter allows larger capacity LPG tanks to be connected to new regulators, facilitating more efficient connection and disconnection. It is made of high-quality brass material, which is corrosion-resistant and leak-proof, ensuring long-term safe use. This product is mainly used for the connection between liquefied petroleum gas tanks and regulators, and is widely used in outdoor activities such as camping and barbecue.

BRASS FEMALE POL CAP 2004 is used for connections in liquefied petroleum gas systems. It uses brass and nickel electroplating surface technology, has extremely strong corrosion resistance and high temperature resistance, and can effectively resist the erosion of the external environment. Its internal O-ring provides a tight seal to ensure the safety of the gas system. This type of cap is suitable for the end of liquefied petroleum gas pipelines that need to be sealed.

The manufacture of POL connectors not only needs to meet strict safety standards, but also requires them to have strong corrosion resistance and high temperature stability to ensure that no failure occurs during long-term use. According to relevant industry standards, POL connectors generally have high corrosion resistance, high temperature performance, sealing and safety. Liquefied petroleum gas is composed of a variety of chemicals, especially common natural gas and propane gas. Materials such as brass and copper alloys are widely used in the manufacture of POL connectors due to their good corrosion resistance, ensuring that they are not corroded by gas during long-term use. POL connectors need to maintain reliable performance at high temperatures, especially in high temperature environments such as cooking, camping and heating. POL connectors need to have excellent sealing performance to prevent gas leakage. This is especially important for liquefied petroleum gas systems, as any leakage may cause safety accidents.
