Abstract
A fluid fitting includes a nut, a sleeve, and a union. The union and the nut may include corresponding stops and corresponding markings. Corresponding stops and corresponding marking may engage with each other when the nut is sufficiently connected with the union. A method of connecting a fitting includes connecting a sleeve of the fitting with a nut of the fitting, connecting the nut with a union, rotating at least one of the nut and the union until a stop of the nut engages a stop of the union, restricting over torque via the stop of the nut and the stop of the union, and verifying a sufficient connection if first markings of the nut align with second markings of the union.
Claims12
A fluid fitting, comprising:
- a nut;
- a sleeve;
- and
- a union, wherein:
- the union includes a stop and the nut includes a stop, together comprising corresponding stops,
- the union and the nut include corresponding markings configured to provide a visual indication of a connection of the nut with the union,
- the markings of the union and the nut have different circumferential widths, and
- a difference in the circumferential widths between the markings of the union and the nut correspond to an expected amount of deformation.
A fluid fitting, comprising:
- a nut;
- a sleeve;
- and
- a union, wherein:
- the union includes a stop and the nut includes a stop, together comprising corresponding stops,
- the corresponding stops contact or engage with each other when the nut is connected with the union in a first connection,
- the corresponding stops provide a first visual indication of a sufficient connection between the nut and the union,
- the nut and the union include corresponding markings configured to provide a second visual indication of a connection of the nut with the union, and
- the corresponding markings of either or both of the nut and the union includes a plurality of visual indicators to indicate a sufficient connection between the nut and a union has been reached for at least one subsequent connection;
- wherein the markings of the union and the nut each has a circumferential width, and a difference in circumferential widths corresponds to an expected amount of deformation;
- and
- wherein the circumferential widths of the markings of the union and the nut define a difference between a minimum rotational position and a maximum rotational position of the union relative to the nut in which the nut and the union are connected,
- a first circumferential edge of the markings corresponds to the minimum rotational position,
- a second circumferential edge of the makings indicates the maximum rotational position, and
- wherein in the minimum rotational position, a gap exists between the nut and the union.
A fluid fitting, comprising:
- a nut;
- a sleeve;
- and
- a union, wherein:
- the union includes a stop and the nut includes a stop, together comprising corresponding stops,
- the union and the nut include corresponding markings configured to provide a visual indication of a connection of the nut with the union,
- the markings of the union and the nut have different circumferential widths, wherein:
- the union and the nut extend along and rotate about a central axis,
- an intersection point is defined where threads of the union intersect with a plane perpendicular to the axis of the fluid fitting,
- a stop angle is defined between the stop of the union and the intersection point, and
- the stop angle is determined based, at least in part, on the expected amount of deformation.
