TG4 Rubber Frame Oil Seal — key benefits and specifications Why choose the TG4 Reliable sealing performance: the rubber frame design provides a tight seal to reduce oil leakage and protect bearings and housings. High chemical and temperature resistance (FKM): the fluorine rubber (FKM) frame option stands up to aggressive fluids and elevated temperatures where standard rubbers may fail. Flexible material options: a butadiene rubber oil seal is also available to meet different application requirements. Easy installation and maintenance: threaded, two-piece construction simplifies fitting and replacement without disturbing adjacent components. Precise fit for consistent performance: inside diameter 145 mm and overall dimensions engineered for accurate mounting and long service life. Key attributes Model: TG4 Inside diameter: 145 mm Size: 145 * 180 * 12 Design: threaded, 2-piece construction Materials: fluorine rubber (FKM) frame oil seal; butadiene rubber oil seal also available Color: FKM (as specified) How it solves problems Prevents lubricant loss and ingress of contaminants, extending equipment life and reducing downtime. FKM material minimizes degradation in harsh chemical environments and at higher operating temperatures. Threaded, two-piece design reduces installation time and risk of damage during service, lowering maintenance costs. Typical applications Industrial gearboxes and rotating shafts: seals lubricants in housings and prevents contamination of bearings. Hydraulic systems and pumps: provides reliable sealing against fluid leakage and system contamination. Engine accessory housings and machinery with elevated temperatures or aggressive fluids: FKM option protects seals from chemical attack and thermal degradation. Specifications summary Product: TG4 rubber frame oil seal ID: 145 mm Dimensions: 145 * 180 * 12 Design: threaded, 2-piece Materials: FKM (fluorine rubber) and butadiene rubber options Color: FKM If you need confirmation of compatibility with a specific machine or shaft, provide the shaft diameter, housing bore, and operating fluid/temperature and we can confirm fit and material suitability.
