The VNS-A4 is a 100mm (4”) straight single-plane cast aluminium swivel with 4” TTMA flanged ends allowing 360° rotation. It may be used on any application where another plane of rotation is required.
For example it may be used on loading arms instead of the coupler spool to enable rotation of the API coupler. Liquip’s grease relief system (grease nipple one side with relief valve mounted opposite for efficient removal of old grease and debris) extends the life of the swivel by ejecting old grease and wear particles. Dual O-Rings are for product seal and dust seal respectively.
