The 704-297 Teflon O-ring is a high-performance sealing component used in various locations within compatible sprayer systems. It is specifically designed for use with 640 i Airless Sprayer; 640 IX Airless Sprayer; 740 i Airless Sprayer; 740 IX; 740 ix Airless Sprayer; Advantage 500; Advantage 600; Advantage GPX 85; Impact 440 service; impact 640 I and IA; impact 640; Performer 640 i Airless Sprayer; PowrLiner 2850 GB_D_F; PowrLiner 1800M, 2800M; RentSpray 500; RentSpray 600 Impact; RentSpray 600; RentSpray 650; RentSpray Plus; and SprayTech GPX 85 models. This O-ring is manufactured from Teflon (PTFE), which offers exceptional chemical resistance and low friction. It is ideal for sealing against aggressive paints, solvents, and cleaners that would degrade standard rubber O-rings. Teflon O-rings maintain their sealing properties over a wide temperature range and resist compression set. They are commonly used in fluid passages, pump connections, and valve assemblies. Over time, Teflon O-rings can become cut, deformed, or lose their sealing ability due to mechanical damage or extrusion. A damaged O-ring will allow fluid to leak, causing pressure loss, mess, and potential damage to surrounding components. Symptoms of a faulty O-ring include visible leaks at sealed joints, difficulty building pressure, or material buildup around the seal area. Replacing a worn or damaged Teflon O-ring with this genuine part restores a positive, leak-proof seal. This ensures efficient operation and prevents fluid loss. When installing, ensure the sealing surfaces are clean and the O-ring is properly seated.
