Spin-On Filters
Integrated filtration solution for oil, fuel, and hydraulic systems | Quick installation, reliable performance, and easy replacement
Product Introduction
Spin-On filters are one of the most common and reliable filtration solutions in automotive, construction, agricultural, and industrial equipment industries. With an integrated design (cartridge and metal housing in one assembly), this filter type provides quick and safe installation, and replacement is done without needing to open the housing. The compact structure, reliable sealing, and stable performance have made Spin-On filters a standard choice in many lubrication, fuel, and hydraulic systems.
Design & Construction Features
Resistant Metal Body
Steel Canister with high working pressure tolerance and resistance to impact and corrosion
Advanced Filtration Media
Cellulose paper or multi-layer synthetic fibers with high efficiency in capturing fine particles
Calibrated Bypass Valve
Ensures oil/fluid flow during clogging or cold start conditions
Anti-Drain Back Valve
Prevents fluid drainage after engine shutdown
Precise Sealing
Heat and chemical-resistant O-ring to prevent leakage
Uniform Quality Control
Pressure, leakage, and separation efficiency testing in each production batch
