REPLACEMENT SWIVEL T-END AIR SPOOL FOR DIVING GAUGE
High Pressure Hose T-End Air Spool with Viton O-rings for Swivel Gauge.
An air-spool sits inside the high pressure hose at the SPG / computer swivel neck.
It is the heart of the swivel mechanism. Yet it is often neglected in gear rinsing and maintenance which allows salt crystal and dirt build-up around the o-rings overtime, making them dried and deformed. And when the o-rings are dried, turning the SPG can break it. That is disaster waiting to happen. This simple yet important part can make or break a diving vacation. Don't leave for a vacation without a spare one, especially if you have not serviced your SPG for a long time. Great item for your save-a-dive kit. This air-spool is Nitrox compatible. It is also compatible with most modern pressure gauges except some old models that can not accept one with a center bushing.
