Pressure and Sampling Adapters
The versatile Jet Test QD® has many uses other than those shown on Bulletin 14. This permanently installed, impact resistant, quick disconnect is unique because only its stainless steel hex is exposed.
Standard Jet Test QD®s require the long actuator. Refueling nozzles such as those made by Avery Hardoll (now known as Meggitt) use a shorter actuator because the long version would interfere with the nozzle strainer. Short versions have suffix S or AH in the model number.
See below for components and variations of these two assemblies.
