Determine Nut, Knob, or T-Handle CodeV01-3-52-00-N-0588-S2 Made-to-OrderClampco V-BAND Couplings, also known as V-BAND Clamps or V-Clamps, join flangeswith V-shaped profiles. A V-BAND coupling operates by exerting a wedging load,which squeezes the flanges together.

2 The V-BAND Couplings can be designed to workwith or without gaskets and O-rings. The material gauge, latch style, and numberof retainer segments all vary depending on the requirements for each application. V-BAND Couplings eliminate theneed for cumber some boltedflange designs and costly weldedflange designs. Because V-BandCouplings can be easily assembledand disassembled, they are oftenused on equipment that requiresfrequent service or V-BAND applica tionsinclude pumps, engines, exhaustsystems, filters, and food andchemical processing equip LATCHThe Clampco T-bolt latch is used for permanent or semi-permanent applications and/or safety on pressurizedsystems. The T-bolt latch is our most economical OVER CENTER LATCHThe light-duty over center latch is used on applicationsthat require frequent assembly or disassembly. No toolsare required for opening and closing the clamp afterinitial installation. This latch style is ideal for light-dutyapplications on small diameters and requires a 3 T-bolt.

3 (Note: Not recommended for pressurized applications)MEDIUM-DUTY OVER CENTER LATCHThe medium-duty over center latch is well suited forheavier applications and on larger diameters. No toolsare required for opening and closing the clamp afterinitial installation. It is available with either a 1 4in. or5 16in. diameter T-bolt.(Note: Not recommended for pressurized applications)HEAVY-DUTY OVER CENTER LATCHThe heavy-duty over center latch is well suited forheavy-duty applications and large diameters. It isavailable with 3 8in. diameter T-bolt.(Note: Not recommended for pressurized applications)SADDLE QUICK RELEASE LATCHThe saddle quick release latch is also used for easeof dis assembly and where the ability to replace bolts isdesired. It is not recommended for diameters larger than10 in.

[ mm] and larger). One-segment retainers are difficult to install 1due to their inherent stiffness. Therefore, they should be used on permanent applications.

5 One-segment retainers can only be used with latch & band styles V01, V02, V03, V07, V09, V01T, V02T, V03T, V07T,and retainers are also generally used forV- band Couplings 8-10 in. [203-254 mm] and , they provide increased installation and2removal flexibility. Two-segment retainers areprimarily recommended for double latch clamps butcan be used with single latch clamps. Please note:Two-segment retainers CANNOT be used with latch& band styles V01T, V02T, V03T, V07T and V09 TNUMBER OFLATCH DESCRIPTIONSEGMENTST hree-segment retainers are used for all couplingdiameters, especially those 8-10 in.

Three-segment retainers can onlybe used with latch & band styles V01, V02, V03,V07 and retainers are only recommendedfor exceptionally large couplings where two orthree segments are not adequate.
