Made from polypropylene, this locknut offers chemical resistance and durability suited to the demands of plumbing and HVAC installations. At 0.34 pounds, it is a lightweight fastener component. Licensed plumbers, HVAC technicians, and pipefitters typically specify polypropylene locknuts where corrosion resistance or compatibility with non-metallic piping systems is required. This part ships as a single unit and is stocked for maintenance, repair, and new construction work.\u003c\/p\u003e\n\u003cp\u003eThe 931-600 locknut is appropriate for residential and light commercial piping, venting, or drainage applications where a polypropylene-rated mechanical connection is needed. It is commonly used when securing bulkhead fittings, conduit connectors, or similar threaded components to panels, tanks, or enclosures. Installers working with PVC, CPVC, or polypropylene piping systems frequently use this type of locknut as part of leak-free assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolypropylene construction provides corrosion resistance and compatibility with chemical-carrying systems\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.34 pounds, reducing load on fittings and assemblies\u003c\/li\u003e\n  \u003cli\u003eDesigned for secure threaded locking in piping, venting, and enclosure applications\u003c\/li\u003e\n  \u003cli\u003eSuitable for use in non-metallic piping system assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service locknut for polypropylene piping and fitting applications in residential and light commercial systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or HVAC technician. Shut off water supply or isolate the relevant system section before disassembling any fittings. Hand-tighten the locknut first to ensure threads seat properly before applying tool pressure. Over-torquing polypropylene locknuts can crack the fitting body, so follow the fitting manufacturer's torque guidance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 038877541364\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TAPCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 931-600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAPCO","offers":[{"title":"Default Title","offer_id":51233670332722,"sku":"931-600","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307615494.jpg?v=1780106352","url":"https:\/\/voomisupply.com\/products\/tapco-931-600-polypropylene-locknut","provider":"Voomi Supply","version":"1.0","type":"link"}
