E-Z Purge Slip Blinds

For line purging applications, past practice has been to use a slip blind and number of spacers sandwiched between the blind and the gapped flange. While this procedure can effectively be used to create a purging area, a number of problems exist which can lead to unsafe practices and/or damage to equipment.

USA Industries new E-Z Purge blinds can help eliminate all of those problems. Our Purge Blinds are easily identifiable and can be made to any specifications requested. The current standard we use is a 1/2" thick 516 Gr70 slip blind with a ¼" deep channel milled at either ¾", 1", or 1 ½" widths depending on the blind size.

The ratio of gasket area versus purge area is approximately 50% to allow for proper sealing force distribution.

Custom configurations available to suit your specific purge flow requirements.

• Any Flange size & rating
• Unique handle identifies it as a Purge Blind
• Painted flat black
• Color coded Handle
• Stamped with Size & Rating
• Q/A & Q/C – Manufactured under our strict Quality Assurance Program
