How to install a screw-in vent correctly - Wuxi Sinceriend New Material Technology Co., Ltd.

Correct installation of a screw-in vent is vital for system safety, efficiency, and long-term reliability. This component eliminates trapped air, regulates internal pressure, and prevents operational disruptions across fluid handling applications. Precision during mounting ensures leak-free performance and protects connected equipment from undue stress.

Confirm system deactivation: Ensure the entire system is fully deactivated and isolated. Verify all internal pressure has been safely dissipated through designated relief procedures.
Prepare workspace: Organize a clean area with lint-free cloths, appropriate hand tools, and selected sealing materials.
Clean and inspect: Thoroughly clean the threaded mounting port, removing every trace of debris, old sealant, or residue. Inspect the vent unit, examining threads for damage, corrosion, or imperfections.
Confirm compatibility: Verify thread compatibility between the vent and port to guarantee seamless engagement.
Apply sealing method: Choose a method suited to the system media and environmental conditions. For thread seal tape, wrap it smoothly and evenly along external threads following the natural spiral direction. For liquid sealant, apply a thin uniform layer to the central thread area.
Alignment and threading: Carefully align the vent with the port and initiate threading by hand. Rotate slowly and steadily, maintaining perfect straight alignment to prevent cross-threading.
Secure tightening: When natural resistance indicates secure hand engagement, employ a suitable wrench with moderate, consistent force. Cease tightening immediately upon firm resistance.
Pressure restoration and inspection: Gradually restore system pressure. Conduct a meticulous visual and auditory inspection around the installation site, watching for moisture seepage, unusual sounds, or other leakage signs.
System stabilization: Allow the system to stabilize under normal operating conditions while maintaining observation. Should any irregularity appear, promptly depressurize and reevaluate the assembly.

A properly installed screw-in vent operates silently and dependably, supporting overall system health. Always prioritize personal safety, consult manufacturer guidance, and approach every installation with patience, expertise, and unwavering attention to detail.
