NORMA GBS Heavy Duty T Bolt Hose Clamp – W2 Stainless Steel Band

The NORMA GBS Heavy Duty T-Bolt Hose Clamp – W2 Stainless Steel Band is built for strength, reliability, and long-lasting performance in demanding environments. With a band and housing made from AISI 430 stainless steel and a tough galvanised steel bolt, this clamp offers strong corrosion resistance and a solid, secure hold—perfect for heavy-duty use across a wide range of industries.

Designed to handle high pressure and vibration, the NORMACLAMP® GBS series delivers outstanding band tensile strength and torque capacity. It’s a trusted choice for securing suction and pressure hoses with plastic or steel inserts, especially where high Shore hardness is required. From commercial vehicles and industrial machines to custom vehicle builds and agricultural equipment, this clamp gets the job done—safely and efficiently.

Features

Durability – The W2 stainless steel band provides excellent resistance to corrosion, UV exposure, and wear, delivering a long-lasting and reliable performance in harsh environments.

High Clamping Force – The T-bolt design ensures strong, uniform pressure around the hose, preventing slippage and leaks even under high pressure or vibration.

Versatility – Available in a wide range of sizes to suit various hose diameters and a broad spectrum of industrial and commercial applications.

Temperature Resistance – Designed to withstand extreme temperature changes, making it suitable for both hot and cold fluid systems.

Enhanced Seal – Offers superior sealing performance compared to standard clamps, reducing the risk of leaks and securing critical connections with confidence.
