Threaded ports are standard reserved connections on air receivers and pneumatic equipment for auxiliary components installation. Compact threaded connections become irreplaceable for small-bore instrument ports, supporting stable operation of the whole air compression system.
Compact structure for small auxiliary fittings
Threaded ports (NPT, G, BSPP) are designed for small-diameter accessories: pressure gauges, safety valves, drain valves, blowdown taps and sensor connectors. They occupy less space compared with flanges, perfect for scattered small interfaces on tank shells.
Fast assembly & on-site maintenance
Direct threaded screwing needs no welding or flange bolt sets. Operators can mount, replace or disassemble valves and instruments quickly for routine maintenance, pressure calibration and drain operation without shutting down the whole pipeline for long.
Good air tightness under medium-low pressure
With PTFE tape or thread sealant applied on threads, the joint achieves reliable sealing for compressed air. It adapts to normal pressure fluctuation of air storage tanks and avoids continuous air leakage.
Flexible function expansion
Reserved thread ports allow later addition of pressure transmitters, moisture separators or branch air pipelines without cutting or welding the pressure vessel body, realizing flexible function upgrade.
Cost control
Thread machining has lower manufacturing cost than flange welding and assembly for tiny ports, effectively controlling the overall production cost of air receivers and pneumatic equipment.
Key Installation Note
Avoid over-tightening to prevent thread cracking on stainless steel tanks; use dedicated thread sealant instead of ordinary raw tape for high-temperature or coastal anti-corrosion conditions.
Thread ports realize quick installation of pneumatic auxiliary parts, convenient maintenance and flexible expansion for air receivers. YCZX reserves standard international thread ports on all air receivers for direct fitting of standard pneumatic accessories to match your system layout.
