The SAE -20 designation identifies the port size this O-ring seals, fitting the corresponding boss fitting to prevent hydraulic fluid leakage at the connection point.\u003c\/p\u003e\n\n\u003cp\u003eBoss seal O-rings at SAE hydraulic ports are subject to compression set and hardening over time, particularly in equipment that cycles through wide temperature ranges, such as hydronic heaters and machines operating in cold climates. A weeping or wet fitting face, visible fluid staining around a port, or a drop in hydraulic system pressure can all indicate a failed boss seal that needs replacement. Replacing the O-ring during any hydraulic line service or fitting removal is standard practice to avoid reassembling a connection with a seal that has already taken a permanent set.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Wacker Neuson models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eE3000, E3000 (5100056440), E3000 (5100056441)\u003c\/li\u003e\n\u003cli\u003eG50\u003c\/li\u003e\n\u003cli\u003eHTC15\u003c\/li\u003e\n\u003cli\u003eRD12A-90, RD12L-90 Fixed ROPS, RD14K-90, RD7A, RD7H, RD7He, RD7Ye\u003c\/li\u003e\n\u003cli\u003eRTD-SC4 Smooth Drum, RTK82-SC3, RTKx-SC3, RTL82-SC3, RTLx-SC3, RTLx-SC3 NAM Standard, RTSC3, RTx-SC2 EU\u003c\/li\u003e\n\u003cli\u003eSM100, SM120, SM60\u003c\/li\u003e\n\u003cli\u003eST27, ST28 (S05-5), ST31 (S05-6), ST31 (S08), ST35 (S06-4), ST37, ST40 (S06-5), ST45 (S06-6), ST50 (S06-7)\u003c\/li\u003e\n\u003cli\u003eSW16 (S05-1), SW17 (S05-2), SW20 (S05-4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43398774390832,"sku":"WACKER-5100041546","price":13.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100041546.jpg?v=1784075441","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-sae-20-boss-seal-o-ring-5100041546-for-rollers","provider":"CCE Industries","version":"1.0","type":"link"}
