Filter driers with o-rings (set of o-rings attached to each supplied Danfoss DML-FS and DCL-FS filter driers). Dehydrator filters with a set of rubber ring gaskets absorb substances contaminating refrigeration ...systems (such as water that can create acids) and, of course, have the role of physical filtration against impurities that can enter the refrigerant circuit.
In the Danfoss DML and DCL range you find face-seal filter driers fitted with a rubber ring for both connections. This type is used in stationary refrigeration systems. Driers with round rubber seals and face seals are normally used in transportation or automotive refrigeration systems and are often referred to as "O-ring" (rubber o-ring) driers.
A face seal filter dryer is actually a standard dehydrator, but with a different type of threaded connection than flared models. The seal between the filter drier and the pipe connection is provided by temperature-resistant o-rings, rubber rings or O-rings using a face seal (face seal - FS, abbreviation that also appears in the product code).
