### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Awesome product.
  

*by J***T on Reviewed in the United States on April 6, 2024*

Love these clamp downs fitting they have give to them so you can move them around a little awesome for projects that are not quite done but you still need it useable.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect for RV with multiple sewer connections
  

*by M***K on Reviewed in the United States on September 3, 2023*

Our  Northpoint RV has two sewer connections - likely due to two bathrooms.  This enabled us to have one permanent connection to the RV park sewer connection which can be accessed from either or both connections at the same time without changing over any plumbing connections.  Size was perfect and the connector is well made.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect fit and solution for my vent pipe leak
  

*by R***N on Reviewed in the United States on January 19, 2024*

Where these 3 vent pipes meet, there must be a slight angle variation that allows a small amount of rain water to leak out. This fitting will make up for that variance and stop the leak.
