Review: ½” flex hose - This flex hose appears to be just the thing, but its light weight gives concern over its ability to handle the operating pressure of my minisplit. Time will tell.

For 410a we braze connections, very few crimp connections I trust at that pressure. ## Customer Reviews ### ⭐⭐⭐⭐ ½” flex hose *by D***. on June 17, 2021* This flex hose appears to be just the thing, but its light weight gives concern over its ability to handle the operating pressure of my minisplit.
