Gland Design for a Static Application; for O-rings in Dovetail Grooves, INCHES
Dovetail grooves are used to hold the O-ring in place during installation or maintenance. This groove design is relatively uncommon as it is expensive to machine and should not be used unless absolutely required. The dovetail groove construction is only recommended for O-rings with cross sections of .139 inch (3,53 mm) and larger.
