Import Brass Screw-In Vents — Buy in Bulk from Supplier in China

Brass screw-in vents from Yongcun Electronics Co., Ltd. are pressure-equalisation devices manufactured from nickel-plated brass, designed for threaded installation into enclosures and equipment housings. The main body uses copper with nickel plating for structural strength and weather resistance, with thread-sealing design rated to IP68 protection against dust and water ingress. These vents incorporate a breathable membrane that permits air and moisture vapour passage while blocking liquid water, dust, and salt ingress. The supplier notes temperature range operation and compatibility with both imperial and metric thread sizes, with non-standard screw specifications accepted on request. Standard packaging is 500 pieces per box.

The nickel-plated brass construction offers typical corrosion resistance suitable for outdoor and industrial environments, with the plating providing a barrier against oxidation and galvanic degradation. The breathable membrane material is not specified in the source data, though industry-standard PTFE or ePTFE membranes are typical for this product category, offering microporous structure with pore sizes in the 0.1-10 micrometre range. The thread-sealing feature ensures gasketless waterproofing when properly torqued into a tapped hole. Protection grades beyond IP68 are selectable according to application requirements, with the understanding that IP68 defines prolonged submersion resistance at manufacturer-specified depths and durations. The vents balance internal and external pressure differentials caused by temperature fluctuations, preventing seal degradation and condensation accumulation within sealed enclosures.

Typical applications include household appliances, audio equipment, communications devices, sensors, outdoor lighting, large LED displays, computer equipment, automotive exterior lighting, and monitoring equipment. Buyers are typically OEMs and system integrators requiring environmental protection for electronic enclosures in variable climate conditions. The direct tapping installation method suits panels where through-hole mounting is impractical, though board thickness compatibility should be confirmed with the supplier. Metric and imperial thread options provide flexibility for global manufacturing supply chains. Buyers should verify thread pitch, major diameter, and minimum panel thickness requirements before specifying.

Yongcun Electronics Co., Ltd. is located at No. 232 Tang Long Zhong Road, Tangxia Town, Dongguan, Guangdong Province, China, with postal reference 5117000. The supplier holds an imported tier classification and a harbor trust tier designation, indicating basic marketplace presence without advanced verification or assurance levels. The response rate is recorded at 0.00 percent with zero average response hours, suggesting either a new listing, limited active engagement, or data capture timing rather than operational incapacity. The supplier's profile does not disclose manufacturing certifications, export licence details, or years in operation.

The listing positions Yongcun as a source of brass screw-in vents with custom thread and protection grade options, targeting electronics and lighting manufacturers requiring IP-rated enclosure ventilation. No information is provided about production capacity, in-house versus outsourced manufacturing, quality management systems, or client references. The contact point named is Ms. Jalila Tang. Buyers should conduct direct due diligence to verify manufacturing capabilities, quality control protocols, and export experience before committing to volume orders.
