Fusheng-specific lubrication system protection
Unlike air filters that only clean incoming ambient air, an oil filter operates inside the compressor’s closed lubrication loop to guard the high-value air end, bearings and rotors from abrasive wear. If you own or service Fusheng air compressors, you are likely familiar with the common tradeoff: genuine OEM oil filters carry premium price tags and long lead times that leave you stranded during emergencies, while cheap generic alternatives often have mismatched threads, poor sealing and subpar filtration that lead to slow oil leaks and accelerated internal component wear. Our SG-1294 oil filter is built as an exact drop-in solution to this problem, fully compatible with Fusheng compressor units and cross-reference 500386, RE174130, P574721, 03663870, 58488892 and HS7694. Every unit arrives brand new and fully pressure-tested, requiring no adapters or modifications for installation. It traps 99% of fine metal wear particles, carbon sludge and oxidation deposits from circulating lubricant, extends oil service life, and prevents costly premature failure of your compressor core components.
High-visibility yellow housing and practical 9-pack sizing
The bright yellow housing stands out clearly even in cluttered, oil-stained compressor rooms, making it easy to locate during routine checks and eliminating the mistake of grabbing the wrong filter part. Manufactured strictly to original Fusheng dimensional blueprints, this filter matches thread pitch, gasket diameter and overall height perfectly, so it seats tight every time and eliminates the persistent slow leaks that plague most ill-fitting aftermarket filters. Inside, high-efficiency blended filter media delivers consistent fine-particle filtration without restricting oil flow, maintaining steady lubrication pressure even during 24/7 full-load operation. It also features a built-in safety bypass valve that opens automatically if the filter becomes fully clogged, preventing oil starvation that can destroy a compressor air end in minutes. Packed 9 pieces per carton, it strikes the ideal balance for small repair shops and end users — enough stock for regular maintenance plus a few emergency spares, without tying up excess working capital or taking up valuable shelf space. It performs equally well for scheduled preventive upkeep and urgent on-site repair jobs.
Straightforward installation tips & reliable shipping service
Following a few simple best practices will dramatically extend the service life of your new oil filter. Always drain and replace your compressor oil at the same time you install a new filter — running old, contaminated oil through a brand new filter will cut its usable lifespan in half. Apply a thin coat of clean compressor oil to the rubber gasket before installation, tighten by hand until the gasket seats fully, then add only a 3/4 turn with a wrench; over-tightening will crack the housing or strip the threads on the filter head. Replace every 2000 operating hours under normal conditions, and shorten the interval to 1000 hours in dusty, high-temperature or heavy-duty industrial environments. We pack all orders in heavy-duty corrugated cartons measuring 38.5×38.5×40cm, with 9 filters per box, each individually sealed to keep out dust and moisture during transit. We keep large stock of this popular Fusheng-compatible model on hand, so 98% of orders ship the same business day, with flexible sea, air and express shipping options to fit your timeline and budget.
