  • Patent number: 3995888
    Abstract: The pipe connector is fabricated from a deflectible type of plastic material and may be easily removed and cleaned when this is necessary. Both the initial construction of the plumbing system and the subsequent removal and repair are facilitated by the specialized construction of the two free ends of the bend portion, each of which has associated with it a resilient clamp which is loosened or tightened through the operation of an associated threaded fastener. The material from which the connector is fabricated is preferably a high density polyprophylene of the clear or transparent type which admits light and permits the homeowner or plumber to inspect the plumbing system and to readily determine whether removal and cleaning is necessary.
