ABSTRACT:
A coupling for interconnecting adjacent ends of spiral corrugated pipe includes a generally cylindrically shaped body having generally tubular ends extending axially outwardly from a circumferential stop. One of the tubular ends defines a substantially continuous spiral or thread which is adapted to threadably connect to one of the adjacent ends of spiral corrugated pipe. The other tubular end of the coupling defines a sleeve which is adapted to slidably receive the other of the adjacent ends of spiral corrugated pipe within the sleeve to thereby interconnect the adjacent ends of pipe. Gaskets may be provided within the coupling to further reduce infiltration or exfiltration at the coupling. In an alternative embodiment, the coupling includes a generally cylindrically shaped body having generally tubular ends which each define a substantially continuous spiral or thread. The tubular ends are adapted to be threadably connected to adjacent ends of corrugated spiral pipe to form an interconnection therebetween.
