Short Comoression Coupling, also known as compression couplers or compression joints, are designed to connect two pipes of the same diameter. They consist of three main parts: a body, a compression nut, and a compression ring.
Single couplings, also known as slip couplings, are another type of coupling used to connect pipes. They consist of two main parts: a body and a slip nut.
Aesthetics – Larger profile may be less aesthetically pleasing while Single coupling compact design suitable for tight spaces.
Installation – requires tightening of compression nut while single coupling requires tightening of slip nut.
