Review on 🔵 Ronteix Universal Blue Silicone Hose: High Performance 2 Inch 90 Degree Elbow Coupler with 4-Ply Design (51MM) by Quinton Martinez

Ronteix Universal 90 Degree Silicone Hose Fitting 2.36 ID I have used this elbow on a 3hp central vacuum system. The inner diameter was exactly 2-3/8" so it fit my 2-3/8" hose perfectly. With two clamps, nowhere. I was concerned that it might collapse on its own if the air in the vacuum hose becomes blocked, but that doesn't happen, not even close. Excellent Silicone Based Knee!
