About the product

In con­trast to those of our com­pet­it­ors, the col­lars we man­u­fac­ture have key flats on the out­er cas­ing. This makes it easi­er to assemble and dis­as­semble the col­lars using a wrench. Our col­lars are inter­change­able with almost all com­mon high-pres­sure fit­tings. Fur­ther­more, our col­lars are made of 1.4404.
