The Model 64910 coupler is the latest coupler design and it supersedes Models 64900 and 60700-1. It is used for air reference pressure control systems.
The lower half of Model 64910 has been completely redesigned. This new lower half incorporates three (3) detent pins, an internal collar locking device and collar lifting handles [both “short” (standard) or “tall” (option “T”)], providing improved ergonomics and operational handling during disconnect.
Two additional coupler models that include this new lower half are also available, Model 64912 for digital pressure control systems, and Model 64913, which is electro-hydraulically controlled.
Earlier coupler Models 64900 and 60700-1 can be retrofitted to gain these new features by changing only the lower half.
