Nitrile (NBR) compounds are well suited to applications involving petroleum-based fluids, oils, and compressed air, making this O-ring a common wear item in pneumatic and hydraulic tool assemblies. Technicians servicing DEWALT equipment replace this part to restore pressure integrity and prevent fluid or air leakage at sealed joints. The dimensions — 40 mm inner diameter with a 1.3 mm cross-section — must be matched exactly to the mating groove to ensure a reliable seal.\u003c\/p\u003e\u003cp\u003eThis O-ring is used as an internal replacement component during routine maintenance or repair of DEWALT power tools and accessories. It is typically installed wherever the original sealing element has become worn, compressed, cracked, or chemically degraded. Proper replacement helps restore the tool to manufacturer specifications and prevents performance loss caused by internal leakage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNitrile (NB\/NBR) rubber compound offers good resistance to oils, fuels, and compressed air environments\u003c\/li\u003e\n\u003cli\u003e40 x 1.3 sizing must be matched precisely to the correct groove geometry for an effective seal\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement part for DEWALT equipment requiring this specific O-ring\u003c\/li\u003e\n\u003cli\u003eCompact cross-section suitable for tight tolerance sealing applications in power tool assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM replacement O-ring for DEWALT power tools and accessories requiring the 910813 sealing element.

Before disassembly, disconnect the tool from its power source and depressurize any pneumatic lines or reservoirs. Inspect the mating groove for scoring or damage before installing the new O-ring, and apply a compatible lubricant to the O-ring to ease installation and reduce the risk of tearing. Avoid using sharp tools that could nick or cut the sealing surface during reassembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eO-Ring Size\u003c\/strong\u003e: 40 x 1.3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Rubber (NBR)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DEWALT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 910813\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51207393935666,"sku":"910813","price":14.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/dewalt-910813-o-ring-40-x-1-3-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
