### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Stopped my filter from screaming like a banshee
  

*by P***L on Reviewed in the United States on August 29, 2020*

My filter had been used for less than 10 days but on the third day of a 6 day trip it started making noises like a bear and a moose were mating (not to mention making me break a sweat from the increased resistance). I used the kit to change the o-rings and lube the various parts, and now it's smooth as butter. Easy to follow instructions, only one of the o-rings took a little effort to remove. From start to finish it took about 10 minutes.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Cleanside Cover NOT included
  

*by E***E on Reviewed in the United States on September 24, 2020*

Product description listed “clean side cover” as being included, but my kit did not include this item.  It turns out this was/is a typo.  What IS included is a replacement for the rubber pad that sits in a pocket in the cover that seals up against the clean side nozzle when the cover is attached to the underside of the filter body.  It is depicted in the product photo as a black cylindrical item just above the lubricant tube cap.  The instructions for the kit lable this as the Cleanside Cover Seal.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars

*by A***L on Reviewed in the United States on October 4, 2018*

Always good to have spare parts on hand for everything.
