Key Features
✔ Permanent, High-Pressure Seal – Once crimped, they maintain constant tension.
✔ Vibration & Slip-Resistant – Ideal for high-movement environments.
✔ Lightweight & Compact – Low-profile design fits in tight spaces.
✔ Corrosion-Resistant – Typically made from stainless steel for durability.
✔ Tamper-Proof – Must be cut off for removal, ensuring security.
