The VNI-A4 is a single plane cast aluminium swivel commonly mounted on outboard end of bottom loading arm, allowing movement of the drop hose and loading coupler relative to the tanker API adaptor.

It has flanged 100 mm (4”) TTMA ends.

The swivel bolts on to the outboard end of the horizontal pipe, above the drop hose, to provide a swing action to enhance the maneuverability of the loading coupler beyond what the hose can do on it's own.

A ball and needle bearing system provides optimum axial and radial load bearing with minimum friction.

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 removing old grease and wear particles. Dual o-rings for product seal and dust seal respectively.
