If your mower or compact equipment uses the Hydro Gear 52114 family of oil filters, this Kefly replacement provides a reliable, high-quality alternative engineered to trap contaminants and guard moving parts. Designed for easy thread-in installation, the filter fits a long list of OEM part numbers so you can service engines quickly and get back to work.

How does this filter protect my engine during operation?

The Kefly filter captures dirt, metal shavings and other debris before they circulate through the lubrication system, reducing abrasive wear and preserving performance. Built from durable materials, it helps maintain steady oil flow for cleaner, cooler operation under load.

• Efficient media captures fine contaminants and particles
• Durable construction resists collapse under pressure
• Maintains oil flow to prevent overheating and wear

What safety features are built into the filter?

This replacement includes both a bypass valve and a check valve to handle real-world service conditions. If the element becomes clogged, the bypass valve permits continued oil circulation to avoid starvation, while the check valve prevents oil backflow at shutdown to reduce dry-start wear.

• Integrated bypass valve for continued lubrication if clogged
• Check valve prevents oil backflow and dry starts
• Valve design reduces risk of sudden pressure loss
