Seamless, Pinch & Ear Clamps

Seamless Pinch Clamps

Seamless Pinch Clamps (KVGT)
These “Tongue and Groove” clamps offer 360° seamless fastening. Due to their seamless design and uniform compression sealing, these clamps are often used in the beverage, automotive, marine, and motorcycle industries. They are manufactured using 300 Series stainless steel and are perfect for poly and braided tubing.

Many of our Pex (PEX) and Seamless (KVGT) clamps and Keystone (KSC) offer our patented crimp lobe technology. This feature ensures that the crimping tool is properly positioned to help eliminate miscrimps . Miscrimps often lead to leaks.
