Built with a brass body and nitrile rubber seal, it handles working pressures up to 3000 psi and opens at a crack pressure of 1.00 psi. The compression x compression end connections accept 0.25-inch tubing on both sides, making installation straightforward without soldering or threading. A stainless steel spring ensures consistent seating force over the service life of the valve. Plumbers, pipefitters, and industrial technicians install this type of valve in hydraulic, pneumatic, water, oil, and gas service lines where reverse flow must be stopped.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for inline installations in residential and light commercial plumbing, compressed air distribution, hydraulic circuits, and fluid control applications where a 0.25-inch compression fitting is already in use. Its compact form factor makes it practical in tight spaces or panel-mounted assemblies. The 3000 psi maximum working pressure rating qualifies it for higher-pressure service runs where standard low-pressure check valves would be insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInline configuration stops backflow without adding bends or offsets to the line\u003c\/li\u003e\n  \u003cli\u003eBrass body provides corrosion resistance in water, oil, and many chemical service environments\u003c\/li\u003e\n  \u003cli\u003eCompression x compression ends accept 0.25-inch tubing with no soldering or threading required\u003c\/li\u003e\n  \u003cli\u003e3000 psi maximum working pressure suits demanding hydraulic and pneumatic circuits\u003c\/li\u003e\n  \u003cli\u003e1.00 psi crack pressure allows flow with minimal upstream pressure drop\u003c\/li\u003e\n  \u003cli\u003eStainless steel spring and nitrile rubber seal resist wear and maintain consistent seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inline check valve for 0.25-inch compression tubing systems operating within the rated pressure and temperature limits of the brass body and nitrile seal materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified technician. Depressurize and isolate the line completely before removing any existing fitting or valve. Observe the flow-direction arrow marked on the valve body to ensure correct orientation in the line. Compression fittings must be tightened to the fitting manufacturer's specified procedure using appropriate tubing inserts where required by the tubing material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Compression x Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrack Pressure\u003c\/strong\u003e: 1.00 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Nitrile Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 4Z-C4L-1-BN-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542450340146,"sku":"4Z-C4L-1-BN-B","price":104.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/026ef624dc0b12799304e597fe9fa731_c9ce6d6e-7faf-4642-82a9-bdb3314c1d67.jpg?v=1785900897","url":"https:\/\/voomisupply.com\/products\/parker-4z-c4l-1-bn-b-check-valve-1-4-inch-compression-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
