Feature 1
  This product has a hook for fixing the body while fixing the lower part of it, so problems caused by the body twisted or swollen after fixing were solved. 

Feature 2
  With existing products, connection cracks were formed while fixing PVC pipes as pipes and adjust rings were swollen together, causing unstable construction from shaking. 

 Adjust rings of this product fixed in the upper plate are designed to adjust just PVC pipes upward and downward, so no connection cracks are formed after fixing and shaking is prevented, facilitating strong and precise construction. 

Feature 3
  As the upper body of vortex has furrows and the sewage plate has swellings, the sewage plate isn’t separated while connecting washing machine hoses.
