Pipe fitting

Abstract

A pipe fitting includes an entry hub, an exit hub, and a cleanout hub. The cleanout hub is coaxially aligned with the exit hub and angularly offset from the entry hub. The pipe fitting also includes a main body that extends between the cleanout hub and the exit hub. The main body defines a main body length that is at least three times greater than the exit hub outer diameter.

1 . A pipe fitting for fluid, the pipe fitting comprising:
 an entry hub defining an entry point for the fluid into the pipe fitting, wherein the entry hub defines an entry hub outer diameter and an entry hub axis;   an exit hub defining an exit point for the fluid from the pipe fitting, wherein the exit hub defines an exit hub outer diameter and an exit hub axis, and wherein the exit hub is offset from the entry hub such that the exit hub axis and the entry hub axis are angularly offset from one another;   a main body defining a main body outer diameter that is less than the exit hub outer diameter, wherein the main body includes a first portion and a second portion;   a branch extending between the entry hub and the main body; and   a cleanout hub that is coaxially aligned with the exit hub and angularly offset from the entry hub, the cleanout hub being removably sealed with a cover so as to prevent fluid from being introduced into the pipe fitting though the cleanout hub during normal operation of the pipe fitting,   the main body extending between the cleanout hub and the exit hub to define a main body length that is at least three times greater than the exit hub outer diameter, wherein the first portion extends from the cleanout hub toward the second portion so as to define a first portion length and the second portion extends from the exit hub toward the first portion such that the branch is entirely received by the first portion, wherein the main body is configured to extend through an exterior vertical wall of a structure, and wherein the second portion defines a second portion outer diameter that is constant along an entire length of the second portion between the exit hub and the first portion.   
     
     
         2 . The pipe fitting of  claim 1 , wherein the main body is configured to be within the exterior vertical wall of the structure. 
     
     
         3 . The pipe fitting of  claim 1 , wherein a distance along the main body between the exit hub and the branch is at least ten times greater than a distance along the main body between the cleanout hub and the branch. 
     
     
         4 . The pipe fitting of  claim 1 , wherein the branch is coaxially aligned with the entry hub axis. 
     
     
         5 . The pipe fitting of  claim 1 , wherein the entry hub, the exit hub, and the cleanout hub have a same cross-sectional shape, and wherein the cleanout hub defines a cleanout hub outside diameter that is equal to the entry hub outer diameter and the exit hub outer diameter. 
     
     
         6 . The pipe fitting of  claim 1 , wherein the exit hub is attached to an associated discharge pipe that extends to an associated sewer. 
     
     
         7 . The pipe fitting of  claim 1 , wherein the second portion is continuous so as to be of unitary construction. 
     
     
         8 . The pipe fitting of  claim 1 , wherein the first portion and the second portion are angularly aligned. 
     
     
         9 . The pipe fitting of  claim 1 , wherein the second portion defines a second portion length, and wherein the second portion length is at least 33% greater than the first portion length. 
     
     
         10 . The pipe fitting of  claim 1 , wherein the entry hub, the exit hub, and the cleanout hub are in fluid communication with one another. 
     
     
         11 . The pipe fitting of  claim 1 , wherein the main body length is at least three times greater than the entry hub outer diameter and wherein the main body length is at least three times greater than an outer diameter of the cleanout hub. 
     
     
         12 . The pipe fitting of  claim 1 , wherein a distance along the main body between the exit hub and the branch is greater than a distance along the branch between the main body and the entry hub. 
     
     
         13 . A pipe fitting for fluid, the pipe fitting comprising:
 an entry hub defining an entry point for the fluid into the pipe fitting;   an exit hub defining an exit point for the fluid from the pipe fitting and an exit hub outer diameter;   a cleanout hub that is coaxially aligned with the exit hub and angularly offset from the entry hub, the cleanout hub being removably sealed with a cover so as to prevent fluid from being introduced into the pipe fitting though the cleanout hub during normal operation of the pipe fitting;   a main body extending between the cleanout hub and the exit hub, the main body defining a main body outer diameter that is less than the exit hub outer diameter, wherein the main body is configured to extend through an exterior vertical wall of a structure; and   a branch extending between the entry hub and the main body, wherein a distance along the main body between the exit hub and the branch is at least ten times greater than a distance along the main body between the cleanout hub and the branch.   
     
     
         14 . The pipe fitting of  claim 13 , wherein the branch includes a cleanout face that faces the cleanout hub and an exit face that faces the exit hub, and wherein a distance along the main body from the exit hub to an exit side junction of the branch to the main body is at least 1.5 times greater than a distance along the exit face of the branch from the entry hub to the exit side junction of the branch to the main body. 
     
     
         15 . The pipe fitting of  claim 13 , wherein the main body includes a first portion and a second portion, the first portion extending from the cleanout hub to a point at which the branch joins the main body and the second portion extends from the point at which the branch joins the main body to the exit hub such that the branch is entirely received by the first portion, and wherein the second portion defines a constant inner diameter and a constant outer diameter along an entire length thereof.
