### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Super product.
  

*by D***D on Reviewed in the United States on March 14, 2021*

I like these products for hydroponics. Be very careful to measure the outside diameter of hole saw. I first used a Lenox 4" saw. The seal leaked. Measured saw it was 4 1/8". Went to another on the shelf and it was exactly 4" no leaks. Good product.

    Rainbarrel overflow
  

*by A***8 on Reviewed in the United States on November 15, 2020*

Summary: Using these 3-inch uniseal for an extra large rain barrel over flow.  These are perfect in this application, instead of installing a bulkhead connector, which is more expensive, and much heavier.Pros: Good fit & finish; rubber is pliable but firm.Cons: None.Conclusion: At $12 for 2, rating these 5-stars.

    Awesome product.
  

*by P***L on Reviewed in the United States on January 3, 2021*

Holy smokes it was hard putting the pvc through it,  but once you get it in, it is really water tight.  Used it on a blue barrel settlement tank that moves 3000gl every hour.  Not a bit of leaking.  Great purchase and product.
