{"product_id":"connector","title":"connector","description":"\u003cp\u003eCopper hose fittings are core connectors in fluid piping systems, primarily used for connection, branching, reversing direction, changing diameter, or sealing. They are compatible with fluids such as gases, water, oil, and refrigerants. The material is mainly brass alloy with surface treatment. Specific applications are as follows:\u003c\/p\u003e\n\u003cp\u003eI. Core Applications\u003c\/p\u003e\n\u003cp\u003e1. Pneumatic Systems (Most Mainstream): Connects air compressors to pneumatic tools such as jackhammers and grinders, or to cylinder\/solenoid valve lines in automated equipment. The quick-connect design supports frequent assembly and disassembly. H62 brass withstands 1.6MPa high pressure and is compatible with PU\/nylon hoses, covering scenarios such as factories, auto repair shops, and 3D printing.\u003c\/p\u003e\n\u003cp\u003e2. Refrigeration and Heating, Ventilation and Air Conditioning (HVAC): Connects air conditioner\/refrigerator copper pipes to compressors. Brass's thermal conductivity is suitable for refrigerant circulation. Conical\/threaded seals prevent leakage.\u003c\/p\u003e\n\u003cp\u003e3. Automotive and Transportation: Dedicated quick-connect fittings for truck brake hoses. Made entirely of copper, they are vibration-resistant, ensuring brake system stability. 4. Water Supply and Drainage \u0026amp; Instruments: Household\/commercial pipe branching\/reduction (e.g., water heater interfaces), laboratory instrument gas line connections; antibacterial properties suitable for drinking water; precision machining suitable for small-diameter pipes.\u003c\/p\u003e\n\u003cp\u003e5. Hydraulics \u0026amp; Machinery: Low-pressure hydraulic oil circuit auxiliary connections, or equipment lubrication\/cooling pipes; ductility and impact resistance.\u003c\/p\u003e\n\u003cp\u003eII. Materials and Processes\u003cbr\u003eMain Material: Industrial-grade brass (copper-zinc alloy), mainstream models H62 (62% copper, high ductility), HPb59-1 (lead-containing, easy to machine), C36000 (American standard, high pressure resistance), balancing strength, machinability, and corrosion resistance;\u003cbr\u003eSurface Treatment: Nickel\/chrome plating for anti-oxidation (silver-white, suitable for precision equipment), natural polishing (low cost, requires moisture protection), tin plating (enhanced conductivity, suitable for electro-pneumatic composite scenarios);\u003cbr\u003eSealing Components: Nitrile rubber (oil resistant), fluororubber (high and low temperature resistant), PTFE gaskets (acid and alkali resistant), combined with double-layer sealing rings or tapered pipe threads (with PTFE tape) to prevent leakage. III. Selection Guidelines: For pneumatic applications, choose quick-connect type (PC\/PL series); for refrigeration applications, choose flared\/compression fitting type; for low-pressure water\/oil applications, choose threaded type. For high pressure (\u0026gt;1MPa), H62 is preferred; for frequent disassembly and assembly, choose nickel-plated type; avoid unpainted type in humid environments. Regularly apply grease to sealing surfaces and avoid prolonged immersion in water to prevent corrosion.\u003c\/p\u003e","brand":"HENAN XINJUNYU","offers":[{"title":"PC4-01","offer_id":45470769971260,"sku":"CON-7412.20","price":10.0,"currency_code":"USD","in_stock":false},{"title":"PC4-02","offer_id":45470771740732,"sku":"CON-7412.20","price":10.0,"currency_code":"USD","in_stock":false},{"title":"PC4-03","offer_id":45470771773500,"sku":"CON-7412.20","price":10.0,"currency_code":"USD","in_stock":false},{"title":"PC6-01","offer_id":45470771806268,"sku":"CON-7412.20","price":10.0,"currency_code":"USD","in_stock":false},{"title":"PC6-02","offer_id":45470771839036,"sku":"CON-7412.20","price":10.0,"currency_code":"USD","in_stock":false},{"title":"PC6-03","offer_id":45470771871804,"sku":"CON-7412.20","price":10.0,"currency_code":"USD","in_stock":false},{"title":"PC6-04","offer_id":45470771904572,"sku":"CON-7412.20","price":10.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0719\/6282\/0668\/files\/FullSizeRender.jpg?v=1780815419","url":"https:\/\/henan-xinjunyu.myshopify.com\/products\/connector","provider":"HENAN XINJUNYU","version":"1.0","type":"link"}
