Sealing Washers & O-Rings
Sealing washers are used to create a reliable seal at the face of the female port. O-rings require a chamfer in the female port to provide a seat for the O-ring. Flat faced ports should use some form of crush washer.

Aluminum Stat-O-Seals are more reliable than steel stat-o-seals. If the rubber inner seal fails to make contact at the port, the aluminum acts as a crush washer for a secure metal-to-metal seal.
