Sealed Bolts

Product Description

High-Precision Self-Sealing Bolts (O-Ring Integrated) Our self-sealing bolts feature a seamless integration of high-strength fasteners with specialized elastomeric seals (such as O-rings). The unique under-head groove design is precision-engineered to prevent seal extrusion and deformation during installation. With a simple tightening process, these bolts provide a dual function of secure fastening and leak-proof sealing, effectively blocking liquid or gas ingress. It is a high-efficiency, reliable alternative to traditional thread-locking adhesives and liquid sealants.

Industry Applications

Widely utilized in New Energy Vehicles (Battery packs, Electric Drive Systems), Hydraulic Transmission Equipment, Outdoor Telecommunications Base Stations, and Underwater Precision Instruments. It is specifically engineered for sealing interfaces with stringent requirements for airtightness, hydraulic pressure resistance, and environmental durability, ensuring the long-term stable operation of core components in complex conditions.
