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.
If you are not sure what size you need, check our Threaded Fitting Guide.
