    Nice coupler, hard to get coupler on 3" tube
  

*by A***K on Reviewed in the United States on July 24, 2018*

Nice 4ply silicone couplers. I did have a tough time getting this over a 3" tube as the coupler is slightly smaller than the advertised 3", but with a little effort I was able to get it to go on. Overall great quality
