Description Tech Team’s #857 Band-Style #304 Stainless-Steel Hose Clamps use a toggle key rather than a screw-style tensioner for ease of use. The clamp fits 3”- 4” (78 – 101 mm) diameter and is 1/2” wide with an oversize key-style turn closure for installation without tools which ensures a good repair and a tight fit. Clamps should be doubled up on both ends of the hose. One with the key/screw on the left, and one on the right. This ensures uniform tension and a tight connection in applications where heat and vibration are present.
