GUARANTEED TO LAST LONGER
FOR AIR-OPERATED DIAPHRAGM PUMPS
GORE™ ONE-UP® Pump Diaphragms are durably versatile. With proprietary PTFE on the wetted side, they last significantly longer than other conventional PTFE diaphragms. Considerably stronger and with greater flex life, they provide a dramatic improvement in service life. Excellent chemical resistance makes GORE™ ONE-UP® Pump Diaphragms very versatile. Suitable for use with virtually all chemicals and in elevated temperatures and pressures, these diaphragms are ideally suited for those general service pumps that are put to one use today and another tomorrow. Satisfaction guaranteed or purchase price will be refunded.
Key Features Made from a proprietary 100% PTFE Bonded to a reinforced rubber backing Patented rib construction Chemically inert and temperature resistant Greater flex life Available for most makes of pumps and sizes	Key Benefits Last longer: replace diaphragms less often Versatility: diaphragms work with any media Cost: lower maintenance and operating costs
