Continuous-duty operations
In plant or machinery running around the clock, filter changes can go from routine to urgent. SPM-OIL-1375 helps you schedule servicing on your own terms, thanks to its robust construction and consistent 25 µm performance under sustained working pressures. The predictable element life supports less frequent shutdowns and maintains oil cleanliness between intervals.
Dusty or contaminated environments
Equipment operating in quarries, mines, or agricultural settings faces a relentless load of airborne particulates. The inorganic microfibre media captures fine contaminants while the 1.75 bar bypass valve ensures oil continues to circulate even if the element becomes heavily loaded, preventing catastrophic starvation. This pairing of efficiency with a safety mechanism keeps engines protected in harsh conditions.
Inventory consolidation across brands
For workshops servicing fleets that cross-reference multiple filter part numbers, SPM-OIL-1375 covers a wide range of brands including Alco, Hengst, Knecht, and Purolator. Stocking one reliable aftermarket option instead of numerous brand-specific filters simplifies procurement and reduces shelf space, without locking you into a single OEM supplier.
Preventive maintenance planning
When you standardise replacement cycles to avoid unplanned downtime, SPM-OIL-1375 offers predictable performance. The combination of a 23 bar burst pressure and a 10 bar collapse resistance gives maintenance planners confidence that the filter will hold up to normal pressure spikes, letting you change elements on a calendar or hour-based schedule rather than reacting to failures.
Compare the specifications to your current filter. SPM-OIL-1375 has a UN 1.1/2-inch female bottom thread, a total height of 305 mm, and an outer diameter of 137 mm. It replaces many branded part numbers from Baldwin, Donaldson, Fleetguard, Mann-Filter, and others. Always verify the thread size and canister dimensions against your housing before ordering.
The filter element is made of inorganic microfibres and is rated at 25 µm. This media is designed to trap particles at that size efficiently while maintaining adequate oil flow. The bypass valve opens at 1.75 bar to ensure lubrication continues if the element becomes restricted, which is a key feature for cold starts or heavy contamination loads.
The canister features a UN 1.1/2-inch female thread located at the bottom. The thread type is UN, and the orientation is female bottom. This is a spin-on style, so you screw it onto the corresponding male threaded spigot on the engine or filter head. No additional adapters are required when the housing matches these dimensions.
An aftermarket filter like SPM-OIL-1375 is built to match the OEM specifications for fit and function. It uses the same filtration rating and comparable materials, so it integrates directly into your existing system. While it does not carry the original brand logo, it delivers reliable protection at a lower cost. We back it with a 30-day money-back guarantee so you can test it with confidence.
Yes, if your machine uses a canister with a 1.1/2-inch female bottom thread, replacement is straightforward. Always depressurise and drain the system per the equipment manual, remove the old filter, lightly oil the new gasket, and spin on the new SPM-OIL-1375 until the gasket contacts, then tighten a further turn. Recheck for leaks after restarting. No special tools are needed beyond a strap wrench.
We supply SPM-OIL-1375 with worldwide shipping and tracking, so you will always know where your order is. Every purchase is covered by our price-beat guarantee and a 30-day money-back guarantee. If the filter does not meet your expectations, you can return it for a full refund within that period.
