SONA Ikron HEK4420135ASSP010 Replacement Spin-On Filter

Our Ikron HEK4420135ASSP010 replacement spin-on filter is a direct replacement in form, fit, and function.
This means the filter will fit and you should expect performance to be equal to or greater than the OEM filter.
Made in America.

Filtration Media used in the Ikron HEK4420135ASSP010 Cross

Our filter media is backed by ISO 16889 multi-pass testing and other ISO/SAE test protocols and the filter is produced in an ISO Certified manufacturing facility.
An ISO Certified manufacturing facility is all about quality control, consistency, responsibility, and being true to the design. Optimized microglass media is used for fine filtration, just like the Ikron HEK4420135ASSP010 spin-on filter to be replaced. Our microglass filters use the optimal amount of media and pleats to ensure high dirt-holding capacity.
The correct number and design of pleats in the element will give you the lowest initial pressure drop. Therefore the filter will take longer to reach its change-out pressure drop which is usually 25 PSID.

Micron Rating for the Ikron HEK4420135ASSP010 direct interchange

This Ikron HEK4420135ASSP010 spin-on filter replacement element is beta-rated. The filter performance is outstanding.
The Beta X = 1000 number means that for every 1000 particles of x size in the fluid only one particle will pass through the filter on average.

  • 10 Micron equivalent to efficiency of 99.9%

Filter Collapse Pressure for the Ikron HEK4420135ASSP010 spin-on replacement

A filter collapse pressure of 304 PSI Burst; 145 PSID Collapse means that if the filter is completely clogged and the build up of pressure reaches or surpasses 304 PSI Burst; 145 PSID Collapse the filter may collapse and allow contamination downstream. Please use a satisfactory safety factor for the filter.

Compatible Fluids

This filter is compatible with the following fluids but pressure drop will vary depending on viscosity and temperature:

  • spin-on Fluid and Machining Fluids
  • Diesel and other fuels
  • Lubricating Oils and Synthetic Lubricants
  • Turbine and Compressor Lube Oils … And many more fluids
