V-BAND CLAMPS/COUPLINGS Made-to-Order Clampco V-Band Couplings, also known as V-Band Clamps or V-Clamps, join flanges with V-shaped profiles. A V-Band Coupling operates by exerting a wedging load, which squeezes the flanges together. The V-Band Couplings can be designed to work with or without gaskets and O-rings. The material gauge, latch style, and number of retainer segments all vary depending on the requirements for each application. V-Band Couplings eliminate the need for cumber some bolted flange designs and costly welded flange designs. Because V-Band Couplings can be easily assembled and disassembled, they are often used on equipment that requires frequent service or maintenance. Typical V-Band applications include pumps, engines, exhaust systems, filters, and food and chemical processing equipment. How to Determine Your V-Band Clamp/Coupling Description Code Clampco’s description code contains 7 segments, each representing a different part of the clamp/coupling. CLAMPCO LATCH STYLES T-BOLT LATCH The Clampco T-bolt latch is used for permanent or semipermanent applications and/or safety on pressurized systems. The T-bolt latch is our most economical latch. QUICK RELEASE LATCH The Clampco quick release latch is used for ease of disassembly and is required where the ability to replace bolts is desired. SADDLE QUICK RELEASE LATCH The saddle quick release latch is also used for ease of disassembly and where the ability to replace bolts is desired. It is not recommended for diameters larger than 10 in. [254 mm] due to trunnion/band interference. Below is a sample description code: V01-3-52-00-N-0588-S2 It’s easy to create your made-to-order V-Band Clamp/Coupling description code, just follow these 7 easy steps: 1. Determine Latch & Band or Strap Style Code V01-3-52-00-N-0588-S2 2. Determine Number of Retainer Segments LIGHT-DUTY OVER CENTER LATCH The light-duty over center latch is used on applications that require frequent assembly or disassembly. No tools are required for opening and closing the clamp after initial installation. This latch style is ideal for light-duty applications on small diameters and requires a 3⁄16 in. diameter T-bolt. (Note: Not recommended for pressurized applications) 3. Determine Retainer Series Code V01-3-52-00-N-0588-S2 4. Determine Product Design Code V01-3-52-00-N-0588-S2 5. Determine Bolt Code MEDIUM-DUTY OVER CENTER LATCH The medium-duty over center latch is well suited for heavier applications and on larger diameters. No tools are required for opening and closing the clamp after initial installation. It is available with either a 1⁄4 in. or 5 ⁄16 in. diameter T-bolt. (Note: Not recommended for pressurized applications) 6. Determine Retainer Inside Diameter Code V01-3-52-00-N-0588-S2 7. Determine Nut, Knob, or T-Handle Code HEAVY-DUTY OVER CENTER LATCH The heavy-duty over center latch is well suited for heavy-duty applications and large diameters. It is available with 3⁄8 in. diameter T-bolt. (Note: Not recommended for pressurized applications)

SPECIFICATIONS 1. DETERMINE LATCH & BAND OR STRAP STYLE CODE (Sample Description Code) Clampco offers several latch styles and latch combinations for your convenience. Choose the code that corresponds with the best design for your application. FULL BANDS: SINGLE LATCH Full Band Styles are recommended where greater strength is required.

V-BAND CLAMPS/COUPLINGS Made-to-Order 3. DETERMINE RETAINER SERIES CODE V01-3-52-00-N-0588-S2 (Sample Description Code) Clampco is currently tooled for over 20 standard retainer shapes. These retainer shapes mate with the most common industrial flange profiles. To arrive at the proper retainer series for your application, please consider the following factors: the design and dimensions of the mating flanges; operating pressure and temperature; whether or not gaskets or O-rings will be used; and what the system will carry (fluid, dry bulk solids, air, etc.). WARNING: The pressure ratings...

DESIGN CONSIDERATIONS Application Loads See the V-Band Clamp/Coupling load formulas on page 36 for applications involving bending moments and/or axial loads in addition to pressure loads. Safety Factor Choose the thinnest material for the application that still meets the performance requirements, including your appropriate safety factor and material and temperature corrections. Retainer Series Retainer series are available in 301/302/304 annealed stainless steel. Other materials are available upon request. To use a standard retainer series the flange apex width (including compressed flat...

V-BAND CLAMPS/COUPLINGS Made-to-Order 4. DETERMINE PRODUCT DESIGN CODE V01-3-52-00-N-0588-S2 (Sample Description Code) The standard design code is “00” for all V-Band Couplings. A unique design code is assigned to custom parts. Custom parts include variations such as different band and retainer materials, non-standard hardware, special retainer profiles, custom markings, and more. Parts with different over center latch designs, along with their corresponding safety features, are also custom items and will receive a special design code. (See pages 30–34 for more information regarding custom...

6. DETERMINE RETAINER INSIDE DIAMETER CODE V01-3-52-00-N-0588-S2 (Sample Description Code) The retainer inside diameter (I.D.) must be specified in .01 in. increments. It is determined by adding the flange outside diameter (O.D.) plus the recommended air gap for the retainer series. The last 2 digits of the code are represented as a two place decimal number without the decimal point. For Example: You have a flange with an O.D. of 5.750 in. designed for use with a 52 series retainer. See 52 series chart to determine what should be added to flange O.D. to get retainer I.D. 1. ADD FLANGE O.D....
