It features a 0.25-inch inside diameter and a 0.50-inch outside diameter, with a working pressure rating of 350 psi. The hose is constructed from synthetic rubber and carries a brown outer jacket for easy identification. It is sold in cut-to-length increments with a 25-foot minimum cut and a total coil length of 575 feet. Licensed trades and industrial maintenance technicians install this hose in pneumatic tool drops, air supply lines, and compressed air distribution systems.\u003c\/p\u003e\u003cp\u003eThis hose is suited for both light industrial and commercial applications where a flexible, push-on connection is required without the need for separate end fittings. The cut-to-length format makes it practical for jobs that require custom hose runs. It performs across a temperature range of -40 degrees F to 212 degrees F, making it appropriate for use in unheated facilities, outdoor service environments, and applications with moderate heat exposure. No barbed insert fittings are included; the hose relies on push-on style barbed fittings purchased separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-on design eliminates the need for clamps or swaged fittings at assembly\u003c\/li\u003e\n\u003cli\u003e350 psi working pressure rated for standard compressed air service\u003c\/li\u003e\n\u003cli\u003eTemperature range of -40 degrees F to 212 degrees F for broad environmental compatibility\u003c\/li\u003e\n\u003cli\u003eSynthetic rubber construction provides flexibility and durability in shop and field use\u003c\/li\u003e\n\u003cli\u003e0.25-inch ID with 0.50-inch OD for use with standard quarter-inch push-on barbed fittings\u003c\/li\u003e\n\u003cli\u003eSold in cut-to-length increments from a 575-foot coil with a 25-foot minimum order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard push-on barbed fittings sized for 0.25-inch inside diameter air hose.

Depressurize and lock out the compressed air supply before cutting or connecting hose. Use a clean, straight cut to ensure a proper seal on the push-on barbed fitting. Inspect the hose and fittings for damage before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Type\u003c\/strong\u003e: Push-On Air Hose\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\u003eWorking Pressure\u003c\/strong\u003e: 350 psi\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: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Coil Length\u003c\/strong\u003e: 575 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Cut Length\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold In\u003c\/strong\u003e: 1-foot increments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.087 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: 821FR-4-BRN-RL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541693792562,"sku":"821FR-4-BRN-RL","price":429.94,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2adabf17b170e326320c72606cc9d408_80d81104-8b68-4772-ac4f-2bb928dbea44.jpg?v=1785882329","url":"https:\/\/voomisupply.com\/products\/parker-821fr-4-brn-rl-push-on-air-hose-0-25-in-id-350-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
