The NORMA GBS hose clamp leaflet details technical features, torque specs, corrosion resistance, and size options.
The GBS series of NORMA hose clamps are designed for sealing and retaining suction and pressure hoses with steel or plastic reinforcements and high shore hardness. They are suitable for commercial and special vehicle applications and feature a mechanically locked closure with no welding points.
The leaflet provides technical data such as recommended tightening torques, corrosion resistance times, band widths, and clamping ranges. It also lists the available clamp types (QR closure and multi‑part version) and gives ordering instructions, including required details like type, clamping range, band width, material, and parts.
| Corrosion resistance (salt spray, W1) | Min. 72 h |
|---|---|
| Surface treatment | No Chromium VI used |
In salt‑spray testing the W1 clamp shows a minimum corrosion resistance of 72 hours.
The GBS series is offered with a QR (Quick Release) closure and a two‑part (multi‑part) version.
Orders should specify the type, clamping range, band width, material, and parts (e.g., GBS QR 43‑47 mm W1).
