• Reinforced nylon injection shell features high impact resistance, resistant to aging and deformation, can withstand collision and vibration in harsh construction environment.
• Multi-layer pleated composite filter media provides large filtration area, stable 100μm filtration accuracy, effectively traps sand, metal particles and rust debris mixed in new hydraulic oil.
• NBR nitrile rubber sealing ring has excellent oil resistance and aging resistance, prevents hydraulic oil leakage at the filler port and stops outside dust entering the tank through thread gap.
• Standard OEM thread size, easy to screw on and off manually without special tools, greatly simplifies oil change and filter replacement work during maintenance.
• Integrated anti-loosening thread design, the filter will not loosen or fall off under long-term machine vibration, maintaining stable sealing and filtering state.
• Low flow resistance design, no obvious flow restriction during oil filling, saves refilling time and improves maintenance efficiency for service technicians.

FAQ 

Q1：What signs indicate the oil filler filter needs replacement?
A1：Severe blockage, filter element damage, shell crack, sealing ring aging and oil leakage at filler port. Blocked filter will slow down oil filling speed significantly.

Q2：What should be noted during oil filler filter installation?
A2：Clean the thread and sealing surface of tank filler neck before installation. Check the old sealing ring for aging damage. Screw the filter gently and tighten properly, do not over-torque to avoid thread sliding or shell cracking.

Q3：What are the common causes of oil filler filter damage?
A3：Excessive tightening force during installation; filter medium clogged by large amount of impurities; impact damage from falling stones; long-term oil immersion leading to rubber seal aging.

Q4：Can clogged filter be cleaned and reused?
A4：Not recommended. Once the filter media is blocked by fine particles, the tiny pores cannot be fully cleaned. The filtration efficiency will drop sharply after washing, impurities will pass through and enter hydraulic system, it is better to install new filter directly.

Q5：How to inspect oil filler filter in daily maintenance?
A5：Check whether there is oil leakage at filler port, observe shell for cracks and damage. When refilling oil, judge if the filling speed is obviously slowed down to check filter clogging condition.

Q6：What trouble will failed oil filler filter bring?
A6：Impurities can directly enter hydraulic tank along with oil. These contaminants will abrade hydraulic pump, valve spool and cylinder seal, causing hydraulic pressure drop, slow movement and oil leakage of the whole machine, resulting in expensive hydraulic overhaul.
