Crafted in-house to ensure the highest quality and performance. Our boom swivels, also known as ‘slewing rings’ or ‘rotating seals’ are used in many industries wherever a gear-operated rotating seal is needed. Available in a variety of sizes and designed for extreme weight and high-stress operation. We focus on manufacturing our products to fit perfectly with your tank and vacuum truck needs.

We build many different custom boom swivels for our customers and have been doing so for years. Our slewing rings and swivel assemblies’ benefit from years of purpose-built design tested by trial and error in the field. Each boom swivel slewing ring is specifically designed with a custom-built moving wiper seal which maintains high vacuum under heavy loads while moving and pivoting.
