Plastic oil and water pipe joints are the "precision locks" of fluid transmission systems. With lightweight, corrosion-resistant, and high sealing properties, they become the core components of connecting pipelines, achieving seamless connection of medium transmission in automotive, home appliance, industrial and other fields, making every interface stable and reliable.
Material segmentation, precise adaptation to media
According to the characteristics of different transmission media, customized material formula is adopted to ensure that the connector is "compatible" with the fluid:
Oil resistant joint: Based on reinforced nylon 66 and added with oil resistant modifier, it can withstand long-term immersion in engine oil and gear oil, with a dimensional stability error of ≤ 0.2mm in an environment of -40 ℃ to 130 ℃. It is suitable for automotive engine oil circuits and hydraulic equipment interfaces, and its oil swelling resistance is improved by 60% compared to ordinary plastics.
Waterproof connector: Made of food grade PP or PE material, the inner wall is smooth and does not scale, certified by FDA, and there is no odor when transmitting drinking water and coolant. The PE version can withstand high temperatures of 100 ℃ and is suitable for water heaters and air conditioning water circulation systems, ensuring fluid purity.
Chemical resistant joint: made of PVDF material, with an acid and alkali resistance of up to 99%, it can resist strong corrosive media such as sulfuric acid and sodium hydroxide, and has flame retardant properties (UL94 V0 level), suitable for complex scenarios such as industrial wastewater treatment and detergent production lines.
Structural innovation, strengthened sealing and durability
Multi layer sealing design: Built in dual silicone sealing rings (temperature resistant -50 ℃ to 200 ℃), combined with tapered threads or snap on structures, achieve "pressure adaptive sealing", withstand ± 0.8MPa pressure fluctuations without leakage, and have a leakage rate of less than 0.01ml/h.
Anti impact strengthening: The joint body is reinforced with a glass fiber layer, which has an impact strength of 15kJ/m ² and can withstand the axial force generated by pipeline thermal expansion and contraction. Its service life exceeds 100000 hours in vibration environments (such as car engine compartments).
Installation flexibility: The quick plug connector can be docked in 3 seconds, with a pulling and inserting force controlled between 30-50N, ensuring a secure connection and facilitating maintenance; The threaded joint adopts a fine tooth design, reducing the number of sealing tape wraps by 50% and increasing installation efficiency by 40%.
Full scene adaptation, covering multiple field needs
Automotive industry: Replace metal joints to reduce weight by 50%, lower vehicle energy consumption, resist engine compartment high temperature and oil pollution erosion, adapt to fuel pipe, coolant pipe, and transmission oil pipe interfaces, and maintain stable connections under bumpy road conditions.
Household appliances: the inlet and outlet pipe joints of washing machines and the evaporator joints of refrigerators are applicable. Food grade materials can prevent odor pollution, and the anti-aging design ensures no embrittlement and cracking for more than 8 years, reducing the hidden danger of water leakage.
Industry and Agriculture: In the hydraulic system of machine tools, the high pressure resistance (up to 4MPa) meets the requirements of working conditions; The interface of agricultural irrigation equipment is resistant to pesticide corrosion, and the UV stable formula is suitable for outdoor exposure, reducing maintenance frequency.
Plastic oil and water pipe joints, with their targeted materials, reliable structure, and convenient installation, build a strong defense line in the "last centimeter" of fluid transmission, balance cost and performance, and become the preferred solution for medium connections in various fields, ensuring safe and efficient transmission every time.
