ABSTRACT:
A split gland having only three parts to obtain effective stability to relative motion of the constituent half-gland members. A large area clamping ring generates a clamping force effective to maintain the alignment between male and female mirror image half-gland members. Ease of manufacture and use result from the reduction in complexity of the present invention.
