Safety Notes

• The Swivel should be packed such that the surfaces coming in contact with the fluid being handled are compatible with that fluid. In case of the use of the swivel in submerged service, this would include the dust seals and ball bearings. We always recommend the use of the stainless steel ball bearings when building a swivel for submerged service, since should the standard carbon steel ball bearings rust together, they make it possible to dissemble the swivel and may affect operation.
• Lubrication should be performed periodically, depending on service and operating conditions. Twice yearly is normally sufficient.
