Constructed with a brass body and brass needle, it connects a 1\/4 inch OD tube via a Poly-Tite fitting on one end to a 1\/8 inch NPTF male pipe thread on the other. The angled configuration allows installation in tight spaces where inline valves are impractical. At 150 psi maximum working pressure, it handles typical low-pressure pneumatic and instrumentation circuits. Licensed plumbers, HVAC technicians, and instrumentation mechanics install this valve in commercial and industrial control line applications.\u003c\/p\u003e\n\u003cp\u003eThis needle valve suits residential and light commercial HVAC systems, refrigeration instrumentation lines, compressed air control circuits, and hydraulic sensing applications where precise throttling of small-diameter tubing is required. The Poly-Tite to male pipe end configuration makes it a direct fit for tubing runs that terminate at threaded pipe ports, such as gauge taps, control valves, and metering circuits. Its compact overall length of 1.07 inches and overall height of 1.53 inches allow installation in confined panel or manifold assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAngled body style for installations where inline clearance is limited\u003c\/li\u003e\n  \u003cli\u003eBrass body and brass needle for corrosion resistance in air and compatible fluid service\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch OD Poly-Tite tube connection on one end for tool-free or compression-style tube attachment\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch NPTF male pipe thread for leak-resistant connection at pipe ports\u003c\/li\u003e\n  \u003cli\u003e150 psi maximum working pressure suitable for standard instrumentation and control line service\u003c\/li\u003e\n  \u003cli\u003eWide temperature range from 0 degrees F to 250 degrees F covers most HVAC and refrigeration ambient conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit needle valve for small-diameter instrumentation and control tubing circuits using 1\/4 inch OD tubing terminated at 1\/8 inch NPTF male pipe ports.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation mechanic. Depressurize and isolate the system completely before removing or installing any valve. NPTF threads are self-sealing by design, but apply thread sealant compatible with the system fluid per IPC and IFGC guidelines where required. Do not overtighten the tube fitting connection on the Poly-Tite end, as brass fittings are susceptible to thread damage under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Angled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeedle Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Poly-Tite to Male Pipe\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 0 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.53 inches\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NV312P-4-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539432440114,"sku":"NV312P-4-2","price":54.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7052902bf239993bd533ef810f9886b.jpg?v=1785840177","url":"https:\/\/voomisupply.com\/products\/parker-nv312p-4-2-angled-needle-valve-1-4-x-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
