Our all-aluminum expansion sealing plugs are engineered for high-integrity sealing in critical processing holes. Manufactured from premium-grade aluminum alloy, these plugs utilize a unique expansion mechanism that creates a robust, permanent interference fit during installation. This design ensures superior leak-proof performance, achieving a sealing rating of up to IP68. Optimized for environments where reliability is non-negotiable, our plugs provide a clean, secure, and vibration-resistant seal without the need for additional sealants or threading.
The definitive solution for permanent, high-performance sealing:
NEV Battery Packs: Sealing coolant channels and air-tightness testing ports in battery enclosures.
Hydraulic & Pneumatic Systems: Reliable closure for cross-drilled holes in integrated manifolds.
Precision Machinery: High-integrity sealing for diagnostic and oil-passage holes.
Automotive Engineering: Critical for powertrain housings and lightweight structural components.
Core Value: Ideal for high-reliability process hole sealing where a permanent, non-detachable, and maintenance-free connection is required.
