Oil Filter
_____
Both oil filters and filter cartridges are designed to restrict the amount of by-products generated during engine operation. We are dealing with soot and metal particles that are formed during the abrasion of working components.
The most important elements of JSL oil filters, which are subject to examination during production - apart from the filter medium - are valves and seals ensuring internal and external tightness and pressure valves. The opening and closing parameters of pressure valves directly affect the proper filtration and prevent the dry start of the engine by limiting the oil flow to the sump after the engine is stopped.
During the laboratory tests, as in case of the other filters, filtration parameters, flow rate and performance are measured (as filter capacity and pressure differences).
Every production batch of JSL filters must successfully pass a rigorous inspection process; each spin-on filter is also checked for leaks.

Spin-on Oil Filter
Heavy-duty Case of drawn steel provides longer life and improved durability.
Anti-Drain Back Valve - keeps oil in filter to prevent engine from destructive “dry starts”. It stays flexible in extreme temperatures.
Mounting Plate made of heavy gage steel prevents deflection (movement) at the gasket sealing surface and provides strong threaded attachment to the engine.
Plate Spring is used instead of the commonly used coiled spring. That allows an increase in the size of the element within the same size of filer canister.
O-Ring Gasket exterior seal in between the filter and the engine body. Usage of height quality rubber ensures leakage free environment even in extreme temperatures.
By-pass Valve is a spring-loaded valve assembly calibrated to a certain pressure to prevent the engine from becoming dry in case of high contamination of media or extremely low temperatures.
