Jubilee® Superclamp 316 Stainless Steel Heavy-Duty Hose Clamps

Jubilee® 316 stainless steel Superclamps are engineered for demanding hose installations where high clamping force, dependable retention and excellent corrosion resistance are required. They are also known as GBS, barrel-hardware or T-bolt-style clamps.

The all-316 stainless steel construction makes this range particularly suitable for marine, offshore, food-processing, oil and gas and aggressive industrial environments where zinc-plated mild steel or standard 304 stainless steel may not provide sufficient long-term corrosion resistance.

Strong, even hose retention

A wide, smooth band distributes clamping pressure across a larger section of the hose without perforations that could cut into the material. The shaped bridge piece spans the gap beneath the fastening assembly, helping maintain continuous contact around the hose and reduce potential leakage points.

The solid trunnion supports the bolt assembly and allows controlled tightening using the correct socket or spanner. Recommended torque, maximum torque, band width and band thickness depend on the selected clamp diameter.

Typical applications include:

Marine pumps, hoses and onboard equipment
Offshore installations and oil and gas equipment
Industrial suction and delivery hoses
Food-processing and production machinery
Pumps, compressors and vacuum systems
Agricultural, manufacturing and heavy engineering equipment
Reinforced automotive and machinery hose connections

Selecting the correct size

Measure the outside diameter of the hose after it has been fitted over the pipe, connector or spigot. Select a Superclamp whose adjustment range contains the installed diameter. These clamps have closely graduated adjustment ranges, so accurate measurement is essential before ordering.

Tighten only to the recommended torque shown for the selected size. Excessive tightening may damage the clamp, hose or underlying fitting. Pressure suitability also depends on the hose construction, fitting, operating temperature, fluid, installation method and equipment manufacturer’s requirements.

This product is primarily designed for heavy-duty hose connections. Suitability for rigid exhaust pipes or high-temperature exhaust systems must be independently confirmed before installation.
