Can the Band clamp with compensation spring FLEX-GEAR HD, 841 series, stainless steel maintain a leak-free seal during large temperature fluctuations and hose shrinkage?

Yes. The Band clamp with compensation spring FLEX-GEAR HD, 841 series, stainless steel is designed to maintain a leak-free seal during large temperature fluctuations and hose shrinkage. The built-in compensation spring.a stack of 10 disc (washer) springs under the screw head.automatically adjusts the clamp diameter while keeping consistent radial grip, compensating for hose shrinkage from cold flow or thermal cycling. This spring action preserves sealing around the full circumference and prevents loosening-related leaks. Intended for heavier applications and significant temperature changes, the clamp also features an internal insert to protect the hose surface. Proper installation (screw end protruding beyond the housing and flattened disc springs) and correct tightening torque (nominal 8.5 Nm, max 14.1 Nm) are required to ensure optimal, leak-free performance.

How does the Band clamp with compensation spring FLEX-GEAR HD, 841 series, stainless steel compensate for hose shrinkage and temperature-induced changes?

The Band clamp with compensation spring FLEX-GEAR HD, 841 series, stainless steel compensates for hose shrinkage and temperature-induced changes using an integrated spring mechanism: under the screw head there is a stack of 10 disc (washer) springs that act as a resilient element. As the hose diameter reduces (due to cold flow, shrinkage, or thermal contraction) the springs compress or extend, allowing the clamp to automatically reduce its diameter while maintaining constant radial pressure and sealing around the hose. This prevents leaks across the entire circumference. Proper clamping is visible when the screw end protrudes beyond the lock housing and the disc springs are flattened. An internal insert protects the hose surface; recommended for large temperature variations and heavier applications. Installation torque: 8.5 Nm (max 14.1 Nm).

Is the Band clamp with compensation spring FLEX-GEAR HD, 841 series, stainless steel suitable for high-vibration applications?

Yes. The Band clamp with compensation spring FLEX-GEAR HD, 841 series, stainless steel is suitable for highâvibration applications. The builtâin spring pack (10 disc/washer springs under the screw head) provides continuous radial compensation, automatically maintaining clamp grip and seal despite dimensional changes from vibration, thermal cycling or material cold flow. This keeps sealing pressure around the entire hose circumference and helps prevent loosening or leaks under dynamic conditions. The stainless steel band and internal insert protect the hose, and correct installation (screw end protruding beyond the housing and flattened disc springs) plus tightening within specified torque (8.5 Nm, max 14.1 Nm) ensure reliable performance in heavier, highâvibration environments.

Additional information

Material	SS – stainless steel

Band clamp with a worm-drive lock, equipped with a spring to compensate for dimensional changes in the connection (hose shrinkage due to cold flow of the material or due to large temperature changes). The spring is a set of 10 disc (Belleville) springs – washers under the screw head. This maintains the clamp’s grip and sealing around the entire circumference of the hose, preventing leakage from the installation. The clamp’s spring mechanism automatically increases or decreases its diameter while maintaining the clamp’s grip. Particularly recommended in the case of large temperature changes for heavier applications. Correct clamping is indicated by the screw end protruding beyond the lock housing and by the flattened disc springs. The clamp’s inner insert protects the hose surface from damage. Installation tightening torque 8.5 Nm (max. 14.1 Nm). Screw/lock material: galvanized carbon steel. Band material: stainless steel 300. Band width: 16 mm (5/8″).
