70-92mm Constant Tension perforated hose clamp with washers and liner
TECHI INDUSTRIAL Constant‑Tension Hose Clamps are engineered to maintain steady sealing force under wide temperature‑fluctuating working conditions. The built‑in Belleville spring washers automatically compensate for hose thermal expansion and contraction, preventing loose joints and potential leakage to achieve reliable, long‑term‑sealing performance. Perfect for automotive cooling systems, industrial machinery, heavy‑duty engines, marine equipment and HVAC piping.

Constant Tension perforated hose clamp Component:
15.8mm High-Tensile Stainless Steel Band: The specified width provides an optimal balance between high surface contact area (for secure sealing on medium to large-diameter hoses) and material efficiency. The band is typically fabricated from AISI 304 or 316 stainless steel for corrosion resistance.

Torque-Calibrated Constant-Tension Mechanism: At the core is a pre-loaded spring assembly (often Belleville washers) housed within the clamp’s take-up mechanism. This assembly is engineered to deliver a consistent, predefined clamping force when the drive screw is torqued to its specified “collapse point.” This ensures uniform installation force across all clamps in a system.
