compression coupling

compression coupling

[kəm′presh·ən ‚kəp·liŋ]
(mechanical engineering)
A means of connecting two perfectly aligned shafts in which a slotted tapered sleeve is placed over the junction and two flanges are drawn over the sleeve so that they automatically center the shafts and provide sufficient contact pressure to transmit medium loads.
A type of tubing fitting.

compression coupling

A coupling used to connect sections of hubless pipe (i.e., pipe without a hub), acid-resistant cast-iron pipe, or glass-pipe; consists of an inner elastomeric gasket and an outer metallic sleeve, with an integral bolt used to tighten and compress the seal.
