Teittinen hydraulic sintered filter

Product Introduction
Teittinen hydraulic sintered filter

Teittinen hydraulic sintered filter

This is a G1/4 specification sintered bronze micro filter designed specifically for hydraulic systems. It integrates a threaded installation interface and a high-precision sintered filter element, which can be directly installed in front of the hydraulic nozzle to efficiently filter the oil and protect the throttle hole from impurity blockage. It is the core protective component of small hydraulic circuits.

1、 Structural and dimensional parameters

Interface specification: G1/4 external thread, compatible with standard hydraulic joints

Installation edge: A/F 8mm, easy to tighten with standard wrench

Overall length: 27 ± 1mm

Internal interface: M5 internal thread, can be directly connected to the nozzle

Key dimensions: internal channel diameter of Φ 5~Φ 7mm, filter outer diameter of Φ 8.6mm

Recommended tightening torque: 25 Nm

Sealing structure: The original 55 ° sealing edge is pressed into a 45 ° angle at the factory to ensure reliable sealing after installation

2、 Core filtering performance

Filter material: Powder metallurgy sintered bronze (filter grade 4)

Powder particle size: 0.250-0.355 mm

Average pore size: 40 μ m

Theoretical maximum aperture: 75 μ m

Filtering effect: It can effectively intercept impurity particles in hydraulic oil, prevent nozzle orifice blockage, and improve system stability and component life.

3、 Design and Advantages

Integrated structure: The filter element and metal body are pressed into one, with no risk of loosening, compact structure, and saving installation space.

Efficient filtration protection: With an average filtration accuracy of 40 μ m, it is specially designed to protect precision components such as hydraulic nozzles and throttle valves, avoiding flow abnormalities and system failures caused by impurity blockage.

Easy installation: Standard G1/4 external thread+8mm edge, compatible with universal tools, can be directly installed in the hydraulic circuit in front of the nozzle.

Durable and reliable: The sintered bronze filter element is resistant to high temperatures, impacts, and corrosion, and can work stably in hydraulic systems for a long time with low maintenance costs.
