The locknut uses a female national pipe straight locknut (FNPSL) threaded connection and is rated to 150 psi working pressure. Measuring 21\/32 inches in length and weighing 0.01 pounds, this compact hardware component meets ISO dimensional standards. It is suited for plumbing, HVAC, and light industrial piping systems where corrosion resistance and reliable thread engagement are required. Licensed plumbers and pipefitters are the primary installers for this type of component.\u003c\/p\u003e\n\u003cp\u003eThis locknut is appropriate for use in residential and light commercial piping systems requiring a 1\/8 inch threaded connection. It is commonly installed in gas, water, or instrumentation lines where a secondary locking element is needed to prevent fitting backout or vibration-induced loosening. The 304 stainless steel construction makes it suitable for mildly corrosive environments and wet service conditions. FNPSL threading allows it to mate with standard tapered or straight-threaded male fittings in low-to-moderate pressure applications up to 150 psi.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance in wet or mildly corrosive service\u003c\/li\u003e\n  \u003cli\u003eFNPSL threaded connection for compatibility with standard pipe thread fittings\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating for low-to-moderate pressure piping systems\u003c\/li\u003e\n  \u003cli\u003eMeets ISO dimensional standards for consistent fit and interchangeability\u003c\/li\u003e\n  \u003cli\u003eCompact 21\/32 inch length suits tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation locknut for 1\/8 inch threaded pipe connections in residential and light commercial plumbing, HVAC, and instrumentation piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system fully before threading or removing any fittings. Use appropriate pipe wrenches or hex tools rated for the fitting size, and apply thread sealant or tape as required by local plumbing codes. Do not overtighten; follow standard trade practice for stainless steel threaded fittings to avoid galling the threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Locknut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPSL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 21\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K419-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51541756215602,"sku":"K419-02","price":20.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/343f24b4f19daff2abda4ce8af94bd7b_b8f79186-c18d-4a08-ba1e-eda5bf8df734.jpg?v=1785884126","url":"https:\/\/voomisupply.com\/products\/merit-brass-k419-02-pipe-locknut-1-8-in-304-ss-threaded","provider":"Voomi Supply","version":"1.0","type":"link"}
