Core Functions & Types
According to application and sealing requirements:
1. Pipe end-sealing cap:
For end closure of PVC water supply & drainage pipes, electrical conduits. Available in cap-on type (fitting over pipe exterior) and plug-in type (inserted inside pipe).
2. Threaded sealing plug:
With internal or external threads for threaded fittings, valves and hydraulic parts. Used with PTFE tape or sealant for better tightness.
3. Drain valve / Special-purpose plug:
Custom-made for special equipment such as farm drain valves and large-bore drain pipes. Made of thickened material with rubber gasket for leak-free performance under high pressure.
4. Combination / Universal plug:
Made of flexible rubber or silicone, with tapered / elastic profile. Fits a range of pipe diameters for easy installation and removal.
Material & Performance Benefits
· Corrosion & ageing resistance:
Excellent acid-alkali resistance, ideal for humid and chemically-exposed environments for long-term service.
· High strength & toughness:
Good impact resistance, anti-brittlement, withstands certain internal pipe pressure.
· Reliable sealing:
Leak-tight performance via solvent cement, threaded connection or built-in rubber gasket, against liquid and gas leakage.
· End-protection:
Protects pipe threads and inner surface from physical damage and contamination during production,
