8000 Series Endura Split Flange Swivels
Overview
Its advanced redundant sealing technology incorporates multiple layers of protection, including a primary seal, backup seal, and environmental seal. This unique design helps prevent product leakage and provides early leak detection, significantly enhancing operational safety and environmental protection.
Built with heavy-duty construction and deep-groove bearing technology, the Endura™ DSF delivers smooth operation, simplified maintenance, and reduced downtime. The innovative split flange design allows quick access to seals without removing ball bearings, minimizing maintenance costs and maximizing system availability.

8000 Series Frequently Asked Questions
The Endura™ DSF is specifically designed for loading arms handling hazardous fluids such as acids, solvents, petrochemicals, and other toxic products.
The swivel incorporates a primary seal, backup seal, and environmental seal, providing three levels of protection against product leakage and emissions.
If the primary seal experiences wear or leakage, product is directed to the leak detection port, allowing operators to identify issues before a secondary seal is compromised.
For critical applications, inert gas can be introduced through the purge port at a pressure higher than the product pressure to help prevent fugitive emissions.
The split flange design provides direct access to seals without removing ball bearings, reducing maintenance time and minimizing downtime.
