NORMA GBS Heavy Duty T Bolt Hose Clamp – W4 Full Stainless

The NORMA GBS Heavy Duty T-Bolt Hose Clamp – W4 Full Stainless is built tough for demanding environments where strength and reliability are critical. Made from high-quality AISI 304 stainless steel, this clamp delivers exceptional durability and resistance to corrosion, making it ideal for use with suction and pressure hoses that have plastic or steel inserts or high shore hardness. It provides a secure, leak-proof hold that performs under pressure – perfect for commercial vehicles, heavy machinery, and specialised industrial applications.

Engineered for both performance and ease of use, the clamp features a smart design that simplifies installation with manual, pneumatic or electric tools. Its bolt comes with an integrated spacer for better clamping force, while the mechanically locked closure eliminates weld points and helps prevent contact corrosion. The band has smooth, rounded edges to avoid hose damage, and its hollow trunnions reduce tension stress, ensuring long-lasting protection and performance. This is a professional-grade solution you can count on, no matter the job.

Applications: This clamp is ideal for use in machine building, agriculture, mining, engines, pumps, filters, irrigation, rail, shipbuilding, and the chemical industry.

Features

Security - Doubling of failure torques for unmatched security.

Reliable - Tripling of band tensile force levels for superior hold.

Durable - Full stainless steel construction for maximum durability and corrosion resistance.
