It measures 4 inches inside diameter, 4.25 inches outside diameter, and 0.125 inches thick with a round cross section. The fluoroelastomer compound delivers a working temperature range of -15 degrees F to 400 degrees F, making it well suited for high-heat sealing applications. The 70-durometer hardness rating places this ring in the hard classification, providing low compression set and resistance to petroleum-based fluids. Plumbers, HVAC technicians, and industrial maintenance trades use this ring wherever a reliable, heat-tolerant static or dynamic seal is required.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for use in residential and commercial plumbing, HVAC refrigeration circuits, hydraulic assemblies, and general fluid-handling systems that contact petroleum products. The fluoroelastomer material also supports vacuum service applications due to its low gas permeability. The wide chemical compatibility spectrum makes it a practical stock item for shops servicing multiple system types. Each order contains 5 rings, and the minimum order quantity is 1 unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton-type) compound with good resistance to petroleum products\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -15 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003e70-durometer hardness (hard rating) with low compression set\u003c\/li\u003e\n\u003cli\u003eLow gas permeability — suitable for vacuum service applications\u003c\/li\u003e\n\u003cli\u003eRound cross section, Dash 242 standard sizing\u003c\/li\u003e\n\u003cli\u003eWide spectrum of chemical compatibility for multi-system use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 242 O-ring replacement compatible with systems and assemblies that accept a 4-inch ID, 4.25-inch OD, 0.125-inch cross section seal, particularly where petroleum-product exposure or elevated temperatures are present.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePower down or depressurize the system fully before removing the old O-ring. Clean the groove and mating surfaces of debris and old sealing compound before seating the new ring. Apply a compatible lubricant to the O-ring prior to installation to prevent tearing during assembly.
