ABSTRACT:
Elastomeric pipe separators (14) are interlocked with an internal stop collar (10a) of a pipe coupling (10) to enable pipes (16 and 18) to be inserted as far as they will readily go into the pipe coupling (10) and yet allow for thermal expansion of the pipes (16 and 18) without damage to the pipes (16 and 18) or coupling (10).
