At Assentech, we proudly distribute OPW’s wide range of swivel joints, extensively employed across numerous industries including chemical, petroleum, petrochemical, refining, mining, distilling, brewing, as well as ink and paint sectors, not forgetting farm irrigation and fertilisation. Design, plant, and maintenance engineers commonly utilise OPW’s swivel joints in applications such as flexible piping systems, loading arms, hose reels, sewer rodding, and wastewater treatment equipment, among various types of process machinery. Their use extends to machine tool coolant transfer, drum filling tasks, and a multitude of in-plant fluid and dry bulk transfer applications.
The key to OPW swivel joints is their versatility. They facilitate the use of rigid metal piping for the loading and unloading of fluids and dry products under pressure or vacuum, removing the complications or risks associated with managing hefty, unwieldy hoses.

- Secure Seals
- Shielded Bearing Chamber
- Long-lasting Bearings
