Title: BLOCK FITTING AND SEAL STRUCTURE
Abstract:
A block fitting for connecting components in a vehicular refrigeration system includes male and female blocks defining aligned bores that provide fluid communication between the assembled blocks. A primary seal member is disposed between the blocks in fluid tight relation. A separate secondary seal member spaced from the primary seal member is provided between the blocks. The seal members are pre-assembled onto one of the blocks to form a pre-assembled sub-assembly. In one form, the primary seal member is retained on the block by a polymeric guide ring.
