This Sonar Swivel-Pin Air-Spool with Standard O-Rings and Short Bullet Design, with chrome plated brass construction, is typically required as a swivel between your high pressure (HP) hose and some types of surface pressure gauges (SPG), or some air integrated console dive computers.
Length: 20 mm
It's also typically used with the AHA-5 adapter to fit some computer transducers with a 15 cm (6 inch) long high pressure hose to a high pressure port on your first stage regulator. Technical divers sometimes need this type of bullet swivel-pin air-spool without shoulders when connecting an SPG on a short 15 cm (6 inch) long high pressure hose to their stage/pony cylinder first stage regulator.
This bullet style air-spool is made from Brass with a Chrome Plated Finish and comes with two standard O-Rings. This air spool should not be used with Enriched Air Nitrox (EAN). It's bullet design enables it to be used with a Surface Pressure Gauge that doesn't require an airspool with a centre bushing.
Essential Save-a-Dive Kit Item
You just set up your equipment for the first dive of your vacation in Saint Somewhere, as you pressurise your scuba regulator system you hear air leakage. As you examine your rig you find that the source of the leak is your Surface Pressure Gauge (SPG) or Air Integrated Computer Console. The worst thing that can happen on a tropical vacation has just happened — No SPG or Dive Computer. Don't leave on a vacation without spare parts that can quickly and easily fix a problem.
Between the High Pressure Hose and the Pressure Gauge/Computer is a small brass pin with an O-Ring on each end called a swivel-pin air-spool. This simple, yet important part can make or break a diving vacation. Don't leave on a vacation without a spare airspool. Why ruin a great holiday because of a few dollars in spare parts.
