Abstract
An improved supply line fitting, installation method and technique for direct installation in the supply lines of a distribution system. An angularly flanged, resilient insert barb being force fitted into an opening in a supply line, seals the opening at three points upon being compressed by an external sealing washer and locking assembly. The locking assembly utilizes an intermediate pressure plate for smooth, distortion free compression, providing a positive internal and external seal of the supply line, and locks the fitting at any point along it's 360 degree rotational axis in preparation for interconnection to a final output device.
Claims12
An insert fitting for a supply line, comprising:
- a supply line defined by wall means and having an opening through the wall thereof;
- a housing having a first end which extends through said opening into a void in said supply line, said housing;
- having an expandable and contractible resilient barb means positioned on said housing and located near said first end and surrounding said first end for sealingly engaging said housing and said supply line, wherein said resilient barb means has a flange near one end of said resilient barb means which is contracted by engagement with said opening upon insertion through said opening and expands after entering said void for sealingly engaging an interior of said supply line, and wherein said resilient barb means has an upper end and said upper end of said resilient barb means extends from said flange through said opening in said supply line to an exterior of said supply line;
- and
- locking means positioned on said housing for causing said flange to sealingly contact said interior of said supply line and said barb means to sealingly engage said housing to seal an engagement of said housing to said supply line.
An insert fitting for a supply line, comprising:
- a supply line defined by wall means and having an opening through the wall thereof;
- a housing having a first end which extends through said opening into a void in said supply line, said housing having threads on an outside thereof and above said first end;
- an expendable and contractible resilient barb means positioned on said housing and located near said first end and surrounding said first end for sealingly engaging said housing and said supply line, wherein said resilient barb means has a flange which is contracted by engagement with said opening upon insertion through said opening and expands after entering said void for sealingly engaging an interior of said supply line, and wherein said resilient barb means has an upper end and said upper end of said resilient barb means extends through said opening in said supply line to an exterior of said supply line;
- and
- locking means which engages said threads of said housing, wehrein said locking means which is positioned by means of said threads to cause said flange to sealingly contact said interior of said supply line and said barb means to sealingly engages said housing to said supply line.
