Claims
- 1. A one-piece water tight connector for flexible non-metallic conduit comprising:
- a generally cylindrical inner body section with a smooth bore therethrough, said inner body section having an exterior end and an interior end and an outer surface;
- an integral ferrule projecting out from said inner body section approximate the midpoint between said exterior and interior ends;
- an integral collar extending from said ferrule toward said exterior end, said collar having an inner surface, said collar furthermore defining an annular channel between said inner surface of said collar and said outer surface of said inner body section;
- integral threads extending from said outer surface of said inner body section, said threads of such a shape and pitch to create a pulling action on an appropriately sized flexible non-metallic conduit that is threaded thereon; and
- a tapered surface on said inner surface of said collar, said tapered surface located at the innermost end of said annular channel where said collar joins said ferrule, said tapered surface forcing any conduit guided therein by said annular channel and said threads to be compressed against said inner body section thereby creating a liquid tight seal.
- 2. The water tight connector of claim 1 wherein the outer diameter of said inner body section is slightly less than the inner diameter of the conduit, the inner diameter of said collar is slightly greater than the outer diameter of the conduit, the outer diameter of said threads is greater than the inner diameter of the conduit, and the inner diameter of said tapered surface at the greatest point of taper is less than the outer diameter of the conduit.
- 3. The water tight connector of claim 1 wherein said threads have a sharp slope on the side of the threads facing the interior end of said connector, said threads have a gradual slope on the side of the threads facing said exterior end of connector, and said threads have a pitch of about five threads per inch.
- 4. A one-piece water tight connector for flexible non-metallic conduit comprising:
- a generally cylindrical inner body section with a smooth bore therethrough, said inner body section having an exterior end and an interior end and an outer surface;
- an integral ferrule projecting out from said inner body section approximate the midpoint between said exterior and interior ends;
- an integral collar extending from said ferrule toward said exterior end, said collar having an inner surface, said collar furthermore defining an annular channel between said inner surface of said collar and said outer surface of said inner body section;
- integral threads extending from said outer surface of said inner body section, said threads of such a shape and pitch to create a pulling action on an approximately sized flexible non-metallic conduit that is threaded thereon; and
- a tapered surface located at the innermost end of said annular channel, said tapered surface forcing any conduit guided therein by said annular channel and said threads to be compressed into the innermost end of said annular channel thereby creating a liquid tight seal.
