T-Bolt Clamps

T-Bolt Band Clamps are frequently installed on coolant and air-intake systems for construction, truck, and bus engines. They are also widely used on duct systems, baghouse equipment, irrigation systems, medical equipment, precleaners, and more.

 

T-Bolt Band Clamps provide leak-proof connections in a wide variety of industrial, commercial, and military applications. We manufacture our clamps from 300 series stainless steel with rounded band edges to protect soft hose materials. Our T-Bolt Clamps provide higher tensile strength, durability, and corrosion resistance than typical worm gear clamps, and are the perfect choice for medium- and heavy-duty applications.
We use 20 mm wide stainless steel band in the production of our clamps. The T-Bolts we use are M6 – 8.8 quality. The nuts used with these clamps are zinc-plated steel, which are self-locking and have nylon insert.
We produce T-Bolt Clamps in two types (regular and spring-loaded) and in various sizes. Spring-loaded T-Bolt Clamps are designed compensate for the thermal expansion in hose and fitting connections. They are especially preferred in applications such as charge air cooling systems.
Below is an overview of the standard T-Bolt Clamps sizes we produce. The values are for regular type and do not include our whole product range.
