High-Contamination Environments
In settings like mining or construction where hydraulic fluid is exposed to heavy particulate loads, the 50 µm wire mesh provides consistent protection. The robust media withstands high differential pressure, extending the life of pumps and valves while reducing unplanned downtime.
Continuous-Duty Hydraulic Systems
For machinery operating 24/7, such as in manufacturing plants, this filter maintains oil cleanliness without frequent change-outs. Its bypass valve prevents flow interruption during cold starts or when the element reaches capacity, keeping production lines running smoothly.
Preventive Maintenance Scheduling
Fleet managers can swap the SPM-HYD-1790 during routine service intervals as a cost-effective alternative to OEM. The predictable performance of the wire mesh media simplifies maintenance planning and helps avoid emergency repairs.
Inventory Standardisation
Since this single part number replaces cartridges from multiple brands including Hydac, it consolidates inventory for workshops servicing mixed fleets. This reduces storage complexity and procurement costs while ensuring a quality filter is always on hand.
Yes, the SPM-HYD-1790 is a direct dimensional replacement for Hydac hydraulic filter elements. It matches the required inner and outer diameters, height, and flow direction. Please verify your existing part dimensions against our listed specifications to confirm compatibility.
This element uses wire mesh media with a 50 µm absolute filtration rating. The mesh construction provides excellent strength and is suitable for retaining larger contaminant particles while allowing high flow rates, ideal for hydraulic oil and lubrication circuits.
The filter has an outer diameter of 114.5 mm, a largest inner diameter of 68.4 mm, and a smallest inner diameter of 65 mm. There are no threaded connections on the element itself; it is a drop-in cartridge designed to seat precisely in the housing of compatible Hydac units.
Our SPM-HYD-1790 is built to match OEM specifications for fit, form, and function. It delivers the same filtration performance and mechanical integrity as the Hydac original but at a more competitive price, supported by our 30-day money-back guarantee.
Installation follows the standard procedure for hydraulic spin-off or in-line housings. Ensure the system is depressurised, remove the old cartridge, clean the housing, insert the new element in the correct flow direction (Out-In), and re-secure the housing. Always replace seals if provided.
Spare Part Mart provides a 30-day money-back guarantee and a price-beat guarantee on this filter. We ship worldwide with full tracking, ensuring you receive your order securely and quickly. Our team is available to assist with any post-purchase questions.
