Spring – High Strength and Stability
Spring is key component of spin-on fuel and oil filters. It is used to spin-on filter and fix filter element in the iron shell when it is vibrated and the oil is flowing.
- High precision
- Fatigue resistance
- Corrosion resistance.

Metal end caps are mainly used for the end closure of paper (filter cloth) and filter screens of heavy-duty vehicle air filter. The two ends of the filter paper and the filter screen are sealed to ensure that all the gas passes through the filter paper (filter cloth) without short circuit.
- Material: galvanized steel plates.
- Thickness: 0.4/0.5/0.6/0.7 mm
- We can customize metal end caps according to original part number.
Spiral Perforated Metal – Center or Outer Tubes
Bypass valve is installed on the spin-on fuel and oil filter. When the filter element is blocked and the oil pressure reaches 100±20 kPa, the bypass valve will automatically open to allow the oil to flow through.
- Stable function throughout the service life
- Valve pressure is suitable for engine parameter requirements
- The bypass valve can also play a role at low temperatures (anti-frost) and keep it completely sealed;
- Provide the best fuel supply for the engine.
Cured and Uncured Filter Papers for Air Filters
Filter Paper, Filter Paper, Filter Paper, Filter Paper, Filter Paper, Filter Paper, Filter Materials, Process Management
Filter paper is processed by mixing plant fiber pulp and a little cotton pulp. Because of its fiber structure, leaving numerous tiny holes for liquid particles passing through and leaving solid particles out, which is the basic principle of solid and liquid separation.
- The filter paper can separate impurity particles from the liquid and extend engine and auto service life.
- High filtration efficiency. 98% filtration efficiency of 4 µm particles and 99% filtration efficiency of 6 µm particles.
- Up to 800 L/m2/s air permeability.
- Oil filter paper can withstand up to 600 kPa pressure.
- Up to 70 70 mN/m high stiffness of cured filter paper.
