Finally, simply reinstall the dust cap to complete the installation.
• Practical Function: This automotive air conditioning valve core kit focuses on system protection as its core function. It achieves excellent leak prevention through the combination of tapered surfaces and sealing gaskets. Additionally, this kit filters impurities and stabilizes pressure relief, reducing the risk of system damage to the compressor.
