Built with a compression x compression end connection and a 1\/4 inch pipe size, it installs into tight plumbing runs without the need for threaded fittings. The valve carries a maximum working pressure rating of 6,000 psi WOG (water, oil, gas) and opens at a crack pressure of 1 psi, making it suitable for systems that require low-resistance forward flow with reliable reverse shutoff. Both the body and spring are stainless steel, providing corrosion resistance in demanding service environments.\u003c\/p\u003e\u003cp\u003eThis check valve is used in industrial, HVAC, and process plumbing applications where high-pressure inline backflow prevention is required. Its compact inline design and compression fittings make it a practical choice for instrument tubing, refrigeration, hydraulic, and pneumatic circuits. Licensed plumbers, pipefitters, and HVAC technicians typically specify this valve in systems handling water, oil, or gas at elevated pressures. The 1\/4 inch pipe size suits smaller-diameter tubing runs common in instrumentation and control line installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6,000 psi maximum working pressure rating suitable for high-pressure WOG service\u003c\/li\u003e\n\u003cli\u003e1 psi crack pressure allows low-resistance forward flow in sensitive systems\u003c\/li\u003e\n\u003cli\u003eStainless steel body and spring construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eCompression x compression end connections for tool-accessible installation without soldering or threading\u003c\/li\u003e\n\u003cli\u003eInline configuration simplifies integration into existing tubing runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style inline check valve replacement for high-pressure plumbing, instrumentation, and process systems using 1\/4 inch compression fittings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IPC guidelines. Depressurize and isolate the system completely before removing the existing valve or installing this unit. Verify that tubing ends are cleanly cut and deburred before seating the compression fittings to ensure a leak-free connection. Confirm the flow direction arrow on the valve body is oriented correctly within the line before final torque-up of fittings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 6000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrack Pressure\u003c\/strong\u003e: 1 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4A-C4L-1-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543599513906,"sku":"4A-C4L-1-SS","price":115.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba588276d9508b2abc825d0f005e70e9.jpg?v=1785920830","url":"https:\/\/voomisupply.com\/products\/parker-4a-c4l-1-ss-check-valve-1-4-in-comp-x-comp-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
