Import 300373 Hydraulic Coupler Filter — Buy in wholesale FOB from Supplier in China

The 300373 Hydraulic Coupler Filter is a replacement filter element designed for fluid power systems, specifically for use in hydraulic coupler applications where contamination control directly affects coupling performance and service life. This filter cross-references multiple industry part numbers including FRT4701ELG2G, FRT9701ELC6G, FRT9702ELC6G, FRT9702GDC4G, FRT4701GDE1G, FRT6201GDD2G, FRT9001GDC5G, and FRT9801GDF1G, as well as A8061-14-01, 8021-13-04, and the LX series (LX-600, LX-730, LX-DLA-920, LX-DLA-790, LX-DLA-620) and SLXA series (SLXA-900/240, SLXA-700/240, SLXA-800/280, SLXA-900/280, SLXA-600/240). The manufacturer also produces variants under codes 8061-13-04, 8061-14-01, 8051-13-08, 8051-14-02, A8021-13-04, and A8021-14-05. Filter media construction, nominal micron rating, and collapse pressure differential are not stated in the source data and should be confirmed directly with the supplier.

Hydraulic coupler filters of this type typically employ multi-layer glass fibre or cellulose-based media with a wire mesh support layer to withstand cyclic flow and pressure pulsation common in transmission and torque converter systems. The LX and SLXA prefixes in the cross-reference list suggest compatibility with major Chinese OEM hydraulic systems, including construction machinery, mining equipment, and agricultural tractors. Standard industry practice for such filters specifies a beta ratio of at least 1000 for critical systems, though the exact beta ratio and ISO contamination cleanliness target (typically ISO 4406 18/16/13 or better) for this element require supplier confirmation. The filter housing interface, seal material (usually Viton or nitrile depending on fluid compatibility), and bypass valve setting (if fitted) are structural details that vary by application and must be matched to the specific coupler model.

Buyers for the 300373 filter include hydraulic system rebuilders, construction machinery parts distributors, mining equipment maintenance contractors, and agricultural machinery service centres. The filter is sourced in replacement aftermarket channels rather than as original equipment, with demand driven by machine-hour-based maintenance schedules. Typical procurement involves cross-referencing the failed element part number against interchange lists, then verifying dimensional compatibility of the seal groove and thread or bolt pattern. The supplier operates from Xinxiang City in Henan Province, a concentration area for China's filtration industry. No MOQ, lead time, packaging specification, or incoterms are stated in the listing, so buyers must negotiate these terms directly.

Xinxiang Shunhe Filter Equipment Co., Ltd. is located at 800 metres west of the intersection of Hongli Avenue and Weiyuan Road in Makino District, Xinxiang City, Henan Province, China, postal code 453002. The company's trust tier is classified as harbor, with a response rate of 0.00 percent and an average response time of zero hours. These response metrics indicate that direct communication through the platform has not yet been established, so buyers should expect to initiate contact through alternative channels and verify responsiveness before relying on quoted lead times.

The supplier's product range focuses on hydraulic and industrial filter elements, as evidenced by the extensive cross-reference list spanning construction machinery, mining, and agricultural equipment applications. No information is provided about year of establishment, factory size, annual output, number of employees, revenue, export markets, specific certifications (such as ISO 9001 or ISO 2941), or named customers. Buyers should request a factory profile, quality management system certificates, and test reports for filter element performance (including multi-pass test data to ISO 4548 or equivalent) during initial due diligence. The concentration of filter manufacturers in Xinxiang may offer logistics advantages for consolidated shipments, but this should be confirmed with the supplier directly.
