Abstract: A multi-positionable sediment trap for use with a vapor delivery pressure system. The main body of the adaptor is tubular with the opposite ends extending into end caps. A diverter tube is sealingly and fixedly mounted to one end cap, whereas an outlet control tube is sealingly and fixedly mounted to the opposite end cap. Each tube is located off center relative to the longitudinal axis of the main body forming a sediment chamber into which is directed the gas and sediment from the diverter tube with the gas then flowing from the sediment chamber to the outlet tube. A flared cone filter is mounted within the outlet tube.

Abstract: A vapor delivery pressure test adapter for integral installation at the outlet of a vapor delivery pressure regulator within a self-contained vapor delivery system, comprising a vapor pipe nipple compatible with such system, with vapor filter means internally and fixedly mounted within the nipple, and delivery pressure test adapter means externally and piercingly mounted to the nipple to permit intermittent external measurement of vapor delivery pressure within the system.

Abstract: An O-ring seal for installation in an LP gas cylinder valve with a method and tool for installing the seal in the valve. The LP gas valve includes an outlet passage opening into a chamber within the main body of the valve which in turn is connected to a passage which opens into a cylinder tank. The outlet passage threadedly receives a hollow cylinder through which a stem projects. The stem includes an enlarged bullet shaped end projecting through an annular seat within the outlet passage and into a tapered portion of the outlet passage. An O-ring seal is installed on the annular seat effecting a seal between the valve and stem while spacing the enlarged bullet shaped end of the stem from the tapered portion of the outlet passage. A plate wrench has a hexagonally shaped hole through which a hexagonally shaped nut on the hollow cylinder projects. The wrench is used to tighten the stem with respect to the O-ring seal. Means are provided on the plate wrench for storing spare O-ring seals.

Abstract: A fitting for connection between two locations in a transfer system whereby fluid or gaseous substances pass from one point to another through the fitting. The fitting comprises a hollow cylinder, a hollow stem with an enlarged bullet-shaped head and slidably extending through the cylinder, a passageway providing an escape path of least resistance to leaks occurring between the bullet-shaped head and corresponding fitting in a unit into which it is placed and an annular depression at one end of the hollow cylinder, at which leaks can be detected and, if desired, a leak-test location label can be applied. The hollow stem includes a circumferential groove which is located adjacent to the annular depression, the combination providing a means for retention of leak-test solution.
