SERVICE INFORMATION
When servicing the O-ring on an A/C high or low pressure hose, please be aware that there are now two types of hose flange pilots, and the O-rings are
not interchangeable between the different types of hose flange pilots.
As shown in the drawing below, the current style hose flange pilot is straight and uses a large cross-section O-ring. The new style hose flange pilot
features a built-in O-ring groove, and uses a small cross-section O-ring.
