Quick connect arrangements for securing together first and second tubular members. A securing sleeve helps secure the connection together and include locking arrangements which ensure that the securing sleeve cannot be inadvertently unthreaded.

An industrial process transmitter includes a main housing, a sensor body, and a flange member. The main housing contains transmitter circuitry and includes a first threaded portion. The sensor body includes a process sensor and a second threaded portion in threaded engagement with the first threaded portion. One of the first and second threaded portions includes a threaded cylindrical projection, and the other includes a threaded cylindrical bore. The flange member is received within a groove of the projection. Movement of the sensor body relative to the housing along an axis of the bore is restricted to an axial distance through engagement between the flange and the first or second threaded portion that includes the threaded cylindrical bore, and engagement between the main housing and the sensor body. Rotation of the sensor body relative to the housing about the axis is limited by the axial distance.

Example aspects of a nozzle cap spacer for a hydrant nozzle cap, a spaced nozzle cap assembly, and a method for adjusting a rotational indexing of a nozzle cap are disclosed. The nozzle cap spacer for a hydrant nozzle cap can comprise a spacer body defining an outer body edge; and a resilient first spacer spring arm extending from the outer body edge, wherein the first spacer spring arm is biased away from the spacer body in an extended orientation.

A connector element is disclosed in accordance with one embodiment of the present disclosure. The connector element is for coupling a first tubular element to a second tubular element, wherein the second tubular element is having an end configuration selected from a threaded end configuration and a non-threaded plain configuration. The connector element is having a threaded element complementary to the threads of the threaded end configuration of the second tubular element, a tube lock that is co-axially arranged with respect to and disposed downstream of the threaded element for holding the second tubular element, and a guide element that is co-axially arranged with respect to and disposed down-stream of the tube lock for guiding the second tubular element.

A hydraulic adapter unit includes a hose connecting member and a pipe member. The hose connecting member is a substantially cylindrical hose connecting member, and includes: a hose fixing portion positioned at one end side of the hose connecting member and to which the hose is fixed; a first combining portion positioned at the other end side of the hose connecting member; and an intermediate portion linking the hose fixing portion and the first combining portion. The pipe member includes: a substantially tubular pipe body; a second combining portion disposed at the one end side of the pipe body and separably combined to the first combining portion of the hose connecting member; and a flange portion disposed at the other end side of the pipe body and formed so as to project outward in the radial direction of the pipe body and fixed to a hydraulic device.
