  • System, method and apparatus for plumbing fitting with removable sampling valve
    Patent number: 9342077
    Abstract: A plumbing assembly includes a plumbing fitting having a body. The body includes a main body portion having a main bore extending there through. A peripheral body portion extends from the main body portion. The peripheral body portion includes a distal end and a sampling bore extends through the peripheral body such that the sampling bore is in fluid communication with the main bore. The plumbing assembly further includes a sampling valve threadably coupled to the distal end of the peripheral body portion of the plumbing fitting.

  • Tolerance ring assembly
    Patent number: 9206853
    Abstract: A tolerance ring has a band (16) with outwardly extending corrugated protrusions forming waves (2) which engage a surface (8) of the bore (4) in a housing (5). At one end of the tolerance ring is an outwardly flared guide surface (15a) extending axially from the band (16). The guide surface (15a) acts as an enlarged entrance to the band (16) from a shaft (3) to be mounted in the bore (4) by insertion into the tolerance ring. The use of the guide surface (15a) assists assembly and reduces or eliminates particle production. It is also possible for the corrugated portions to extend inwardly, for the guide surface to be inwardly flared, and for the tolerance ring to be mounted on the shaft prior to insertion in the bore.
