China IP67 Waterproof Breathable Pressure Valve Breather from Reliable Suppliers - Factory Direct ECU Vent Plug
Introduce
The engine control unit (ECU) is the main component of the electronically controlled vehicle that continuously monitors and controls the operation of the engine. The ECU tests and calculates the air-fuel mixture ratio and engine ignition advance angle based on data input from multiple sensors (including MAP sensor, throttle position sensor, air temperature sensor, oxygen sensor, etc.). They monitor and control the engine's fuel supply, injection timing, ignition shutdown angle, engine idle operation and other vehicle ancillary systems in real time to maintain optimal energy conversion rates.
The ECU has a complex structure and is exposed to harsh environments during operation and requires special protection. For example, because heat dissipation from the controller's electronic components causes frequent temperature changes in the work area, breathable products that can both dissipate heat and equalize pressure are required.
The specific requirements for breathable products are as follows
- Great breathability
- High IP rating
- Long-term heat resistance
- Resistant to salt spray corrosion
A stable ECU is the basis for normal engine operation. The excellent performance of IPRO's weldable waterproof and breathable membrane can effectively improve its stability. The XZP snap-on waterproof and breathable valve has two interface types: SFVA and SFVS. The SFVA series corresponds to an opening size of 6.4mm, and the SFVS series corresponds to an opening size of 10.4mm. XZP snap-on waterproof and breathable membrane is made of high WEP and precision welding technology, which can achieve IP ratings of IP67, IP68 and IP69k; the shell is made of a combination of PBT and ePTFE, which has the characteristics of low water absorption, heat resistance, chemical corrosion resistance, etc. In addition, XZP has also launched two types of heat-resistant, waterproof and breathable membranes with working temperatures up to 120°C and 150°C to meet the temperature-resistant needs of different customers.

Frequently Asked Questions
The ECU acts as the main controller of an electronically controlled vehicle. It monitors and controls engine operations in real time, including fuel supply, injection timing, ignition shutdown angle, and idle speed, based on data from various sensors to maintain optimal energy conversion.
ECUs are exposed to harsh environments, and the heat generated by their electronic components causes frequent temperature fluctuations. Breathable products are essential to dissipate heat, equalize internal pressure, and prevent moisture entry.
ECU protective vents and membranes must offer great breathability, high IP ratings, long-term heat resistance, and excellent resistance to salt spray corrosion.
The SFVA series corresponds to an opening size of 6.4mm, while the SFVS series corresponds to an opening size of 10.4mm, allowing customers to choose based on their specific hardware dimensions.
XZP snap-on membranes achieve IP67, IP68, and IP69k protection levels. The shell consists of a PBT and ePTFE combination, offering low water absorption, heat resistance, and chemical corrosion resistance.
IPRO provides specialized heat-resistant, waterproof, and breathable membranes designed to operate reliably at working temperatures up to 120°C and 150°C.
