When connecting to the glad hands, at what angle should the two seals be positioned?

When connecting the glad hands, positioning the two seals at an angle of 90 degrees is crucial for ensuring a secure and airtight connection between the tractor and trailer. This correct angle allows the locking mechanisms to align properly, minimizing the risk of leaks and ensuring that the air supply for brake systems operates efficiently. A 90-degree alignment helps the seals to engage fully, enhancing safety by preventing air pressure loss that could lead to brake failure or other functional issues in a combination vehicle. Proper alignment also avoids unnecessary stress on the glad hand components, extending their lifespan and reliability during operations.
