Aseptconn clamps are designed and manufactured for use in the Food & Dairy, Chemical and Pharmaceutical industries where standard tube/pipe couplings (tri-clamps) are required. Clamp segments & wingnuts are produced by investment casting to ASME SA 351 / A 351 M. Eyebolts & rivets are produced from ASME SA 580 / A 580 M Stainless wire. The threads are rolled to reduce galling. The assembled components are then barrel polished to produce the high quality finish demanded throughout the industry. Quality and precision in manufacture combined with the unique design of our groove profile, produce a clamp with the best joint efficiency for this type of connection. Our recommendation: If repeated tightening is required after using the clamp, this may indicate that the seal may need to be replaced.
