No-Ledge Coupling

Part of the visionary Clean Design Initiative, the Quick Clamp No-Ledge coupling is designed for food and light industry conveying of fragile materials or materials requiring a high degree of sanitation. Unlike a compression coupling, which can have frequent pipe misalignment during installation, the Coperion Quick Clamp No-Ledge coupling delivers a machined tolerance joint.  This ensures proper alignment and creates a ledge-free interior environment on connection points.  As a result, friction and crevices which catch product and cause fines are greatly reduced. 

The Quick Clamp No-Ledge coupling offers a recessed O-ring gasket that delivers a smooth transition through a positive sealing metal-to-metal joint.  This eliminates gasket contact with the product stream—a critical improvement in sanitary piping system design.  Quick Clamp No-Ledge couplings are available with a single T-handle or nut, or backing flanges that tightens the clamp around the male and female flanges. The clamp presses the face of the male and flanges together by way of a bevel on the edge of each flange compressing the o-ring creating an air tight seal.  Lightweight design and a tool-free assembly option speeds installation.

Quick Clamp No-Ledge couplings can be also used in applications where color-changeouts are common; or for hazardous or inert materials where piping connections must maintain a positive seal.  A significant improvement, the Quick Clamp No-Ledge coupling is now available in extended sizes from 3” to 16”.
