Clampco Products

T-Bolt Band Clamps

T-Bolt Band Clamps provide leak-proof connections in a wide variety of applications. T-Bolt Band Clamps provide high tensile strength, durability, and corrosion resistance using 300 Series Stainless Steel bands with rounded edges to protect soft hose materials.

Clampco also offer T-Bolt Band Clamps to Military specification MS21920 manufactured in accordance to MIL-DTL-8783 for use on various aircraft applications including ducting, hose and flexible tubing.

V-Band Clamps

Sometimes known as Masrman Couplings, V-Band Clamps are frequently installed on heavy duty exhaust systems, diesel engines and turbo chargers. V-Band Clamps have 300 Series Stainless Steel bands and retainers come with standard T-Bolt latches.

The V-shaped retainer profile operates by exerting a wedging load, which in turn compresses the flanges together. V-Band Clamps are designed to work with or without gaskets and O-rings.

Barrell Hardware Clamps

When space constraints prohibit the use of a T-Bolt Band Clamp, Barrell Hardware Clamps offer an alternative, low-profile design. With excellent product performance and attractive appearance, Barrell Hardware Clamps are popular on appearance driven applications such as motorcycle exhausts and race cars.

Straps & Strap Assemblies

For applications which require the secure mounting of custom shapes, heavy-duty Stainless-Steel Straps and Strap Assemblies can be specified to suit in this fully customizable range.

Custom Aerospace & Defence

In Addition to the MS21920 Clamps and legacy Aerospace/Defence part numbers registered against NSNā€™s, Clampco offer the ability for custom solutions including alternative materials, plating, reduced weight, high-temperature, and additional strength options. Materials can include 316, 321, A286, Inconel, Hastelloy, Aluminum, Titanium and 17-7PH.
