Plumbing fittings and methods of manufacturing plumbing fittings for use in drain-waste-vent systems are described herein. The plumbing fittings include a housing having at least one receiving member defining a cylindrical bore for receiving a piping member therein, at least one annular seal fittingly inserted in a receiving member, and an annular locking member dimensioned for receiving the piping member therethrough. The annular locking member includes teeth extending inwardly for locking the piping member within the receiving member. The plumbing fittings also include an annular releasing member inserted within the receiving member and movable between a locking position and a releasing position whereat the beveled portion of the annular releasing member presses against the teeth for releasing the piping member.

A pipe connection compensation device by magnetic fluid sealing comprising a compensation pipe, sealed end cap, coil, annular permanent magnet and tightening rod is provided, designed and configured in a novel manner to ensure the pipe connection compensation device by magnetic fluid sealing achieves a better sealing effect.

A seal assembly has a connector body with a first section and a second section, movable relative to one another. The first section and the second section each has an open end configured for receiving the free end of a pipe. The open end of the first and second sections are each configured for sealing engagement with the free end of a respective pipe. The seal assembly is movable between a first condition, in which the second section assumes a retracted position relative to the first section, and a second condition in which the second section assumes an extended position relative to the first section. A seal member is provided for creating a seal between the first section and the second sections in said first and second conditions. First and second adaptors are provided, each for association with a respective one of said first and second sections of the connector body and configured for securing at the free end of a respective pipe. First and second mechanical interlock arrangements are provided, each for association with a respective one of said first and second adaptors, and each configured for driving the respective adaptor in the direction of the connector body.

A collar having a divided structure and surrounding a fitting connection part between a spigot portion and a socket portion in a sealed state is externally mounted over both pipe portions. A first disengagement blocking part that blocks, by contact, a relative disengagement movement beyond a certain level between the socket portion and the collar is provided at a location where the collar and the socket portion side face each other. A second disengagement blocking part provided with a retaining part in which falling-off resistance between the retaining part and an outer peripheral surface of the spigot portion increases according to a disengagement movement of the spigot portion is provided on a pipe support portion side on one end side in a pipe axis direction of the collar.

A compliant jumper tube fitting assembly may comprise an outer housing comprising a first annular cylindrical structure including a first opening defined by a base wall, and an inner housing comprising a second annular cylindrical structure including a second opening defined by an annular wall, wherein the inner housing is configured to generate a seal between an inner diameter wall of the outer housing and an outer diameter wall of the inner housing in response to inserting the inner housing into a mouth end of the outer housing, wherein the inner housing is configured to receive an end fitting and generate a seal between an inner diameter wall of the inner housing in response to inserting the end fitting into the inner housing.

A method of installing a plumbing fixture to an outlet of a water supply assembly located behind a wall includes providing a plumbing fixture including an attachment structure. The method also includes providing an adapter configured to couple the plumbing fixture to an outlet of a water supply assembly. The adapter includes an annular body, a plurality of collars, and an engagement structure. The annular body extends between a first end and a second end and defining a bore extending therethrough. The plurality of collars is provided along an exterior of the annular body and spaced inwardly from the first end such that each of the collars is separated from an adjacent one of the collars in a lateral direction by a recess. The engagement structure is provided along the exterior at the second end.

A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.
