In a situation where theadjustment is quite difficult to achieve,use the recommended torques to change the direction ofthe tubing.

Review: Perfect fittings no issues just make sure when your installing the airline to have a Perfect cut so you have no issues or leaks
Review: High quality. They have No center post so I was able to connect two 1/4” OD air lines together even though they had different ID measurement. One had double the thickness wall so the ID was very small and would not work with a center post.
