## Customer Reviews

### ⭐⭐⭐⭐⭐ Purge bungs
*by  on Reviewed in the United Kingdom 20 December 2023*

I use it for purging pipework great bits of kit

### ⭐⭐ Stiff thread makes it difficult to fit.
*by  on Reviewed in the United Kingdom 18 February 2022*

I had to use grips on the threaded section to stop the whole thing turning while i tightened the wing nut. It does seam to seal okay once in place. Not as good as the Bailey version which uses a nylon nut and has softer rubber.

### ⭐⭐⭐⭐⭐ Five Stars
*by  on Reviewed in the United Kingdom 17 October 2014*

Very well made and robust, I've used it several times without problem.
