A range of swivel adaptors that allow pressure gauges to be connected directly to the system with the dial in the correct orientation. These adaptors have a built in "O" ring seal for pressure gauges with sealing nipple to DIN 16288. The oil flow is restricted to the gauge to dampen any pressure shocks (snubber effect).
