Built with a brass body, this compact valve uses a 1\/8-27 MNPT thread connection and is rated for working pressures up to 300 psi. The cracking pressure is set at 80 psi, and the 7\/16 inch hex size allows for straightforward installation with standard hand tools. At 0.030 pounds, the 46621 is a lightweight, single-point fitting suited for tank and vent service in compressed air and pneumatic assemblies.\u003c\/p\u003e\u003cp\u003eThis valve is used in pneumatic tank applications where a spring-loaded core provides automatic venting or pressure response. The 1\/8 in nominal MNPT connection is a standard thread size found on air tanks, pneumatic reservoirs, and related fittings throughout light industrial and trade environments. The overall length of 1.207 inches keeps the installed footprint minimal, making it suitable for tight mounting locations on tank ports or manifolds. Installation is typically performed by HVAC technicians, pipefitters, or pneumatic system technicians as part of tank assembly or service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass body construction for corrosion resistance and durability in pneumatic service\u003c\/li\u003e\n\u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003e80 psi cracking pressure for spring-loaded core actuation\u003c\/li\u003e\n\u003cli\u003e1\/8-27 MNPT thread connection for standard tank port fitment\u003c\/li\u003e\n\u003cli\u003e7\/16 inch hex size for installation with common hand tools\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 1.207 inches for tight-clearance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for pneumatic tank and vent valve applications using 1\/8 in NPT threaded ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with pneumatic system service. Depressurize and isolate the tank or system completely before removing or installing any valve. Apply thread sealant appropriate for pneumatic service to the MNPT threads and tighten to the hex fitting using a wrench sized for 7\/16 inch. Follow applicable local codes and manufacturer guidelines for pneumatic component service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCracking Pressure\u003c\/strong\u003e: 80 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.207 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.030 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 46621\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67951907340594,"sku":"46621","price":16.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf6477d2974f8f130ea7c90244074950.jpg?v=1791740850","url":"https:\/\/voomisupply.com\/products\/midland-industries-46621-spring-core-tank-valve-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
