will it reduce the airflow?
Marius F Not noticeable as far as my experience. Just one more piece of gear to take care of, some lubrication and o-ring changing now and than-no big trouble
PAUL F I did NOT notice any reduction in airflow when i used it
KENT M no, it is part of the second stage line about 140 psi. i found no restriction and would even accept some for the convenience of the comfort , and the less jaw fatigue by using it.
hope that helps, Bill...
STEPHEN K No it will not. Be careful i found this peice loosening up after a dive or two. Sometime the oring snaps if you tighten it to much. Also you might want to buy a longer low pressure hose for your regulator sometime with this adaption it tends to tug funny with a short stock reg hose. Just get one 6 to 8 inches longer. Thats the best tips for this.
Pete M I have not scientific data to answer this question but I can tell you that I installed it on the rig my girlfriend uses and after a week in Wakatobi she saw no reduction in performance.
