EZ Purge® Slip Blind

Safely Purge While Preventing Equipment Damage from Traditional Methods - Available for Sale or to Rent

USA Industries' EZ Purge slip blind replaces an unsafe and outdated practice for line purging applications that uses a slip blind and several spacers sandwiched between the blind and the gapped flange. Although this procedure can be used to create a purging area, several problems exist that will lead to unsafe practices and/or damage to the operators equipment.

The purge blind creates a "stand off" area at the flange site, that allows for line purging. It seals evenly, resulting in no damage to the flange gasket surfaces associated with using wedges, tubing, or other metals to create space between the blind and flange.

The EZ Purge slip blind is easily identifiable by its uniquely shaped and color coded handle, but we will make it the specification that you request if it is needed. The current standard we use is a 1/2" thick isolation blind with a 1/4" deep channel milled at either 3/4", 1", or 1 1/2" widths depending on the blind size. The ratio of gasket area versus purge area is approximately 50% to allow for proper sealing force distribution.

The blinds come standard in sizes from 1/2" to 96" and flange classes from 150# to 2500#. Unless otherwise specified, the blinds are painted flat black and are stamped with their size & rating for ease of use. Custom configurations are available to suit your specific purge flow requirements. In-stock orders are shipped the same day.
