With a 0.25 inch inside diameter and a 0.50 inch outside diameter, this hose handles a working pressure of 350 psi and operates across a temperature range of -40 degrees F to 212 degrees F. Constructed from white synthetic rubber, it is sold cut-to-length in 1-foot increments with a 25-foot minimum cut length from a 575-foot master coil. Licensed trades and maintenance technicians install this hose for pneumatic tool supply, air distribution headers, and equipment drop lines.\u003c\/p\u003e\n\u003cp\u003eThis hose is suited for residential, commercial, and light industrial pneumatic systems where a flexible, push-on style air line is required. The push-on design eliminates the need for threaded end fittings during hose assembly, simplifying installation in tight or high-volume routing applications. The white color aids visual identification in multi-hose installations. It is a practical choice for compressor room distribution, production floor air drops, and service bay supply lines where flexible routing and pressure reliability are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-on construction for tool-free hose-to-fitting assembly\u003c\/li\u003e\n  \u003cli\u003e350 psi working pressure rated for compressed air service\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 degrees F to 212 degrees F\u003c\/li\u003e\n  \u003cli\u003e0.25 inch inside diameter, 0.50 inch outside diameter\u003c\/li\u003e\n  \u003cli\u003eWhite synthetic rubber construction for easy line identification\u003c\/li\u003e\n  \u003cli\u003eSold in 1-foot increments with a 25-foot minimum cut length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install push-on air hose for standard 0.25 inch ID pneumatic fittings and push-on barb connectors used in compressed air distribution systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician or pipefitter familiar with compressed air system standards. Depressurize and lock out the air supply before cutting or connecting hose sections. Use a clean, square cut and ensure full barb engagement when seating hose onto push-on fittings. Do not exceed the rated 350 psi working pressure, and verify the system temperature stays within the -40 degrees F to 212 degrees F operating range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 350 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.50 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 212 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Synthetic Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: None (push-on)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold By\u003c\/strong\u003e: 1-foot increments, 25-foot minimum cut length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Coil Length\u003c\/strong\u003e: 575 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 18 x 16 x 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.087 pounds (per foot, as priced)\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: 821FR-4-WHT-RL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539087687986,"sku":"821FR-4-WHT-RL","price":389.57,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3880ab88ac3f8ef0f4ac06139d0f36b4.jpg?v=1785834620","url":"https:\/\/voomisupply.com\/products\/parker-821fr-4-wht-rl-push-on-air-hose-0-25-in-id-350-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
