The hose features a 1\/4 inch inside diameter and a 0.5 inch outside diameter, with a 350 psi working pressure rating. Its synthetic rubber construction handles a temperature range of -40 degrees F to 212 degrees F, making it suitable for demanding shop and field conditions. This hose is sold cut-to-length from a bulk coil, priced per 1-foot increment with a 25-foot minimum cut. The blue color aids in quick line identification. Installation requires no end fittings on the hose body itself — it is sold without end connections.\u003c\/p\u003e\n\u003cp\u003eThis hose is used in compressed air systems across HVAC shops, plumbing service vehicles, electrical contractor facilities, and general trade environments. The push-on design is compatible with standard push-on style barb fittings and is appropriate for pneumatic tool lines, air supply drops, and low-pressure control applications. The 575-foot total coil length supports high-volume distributors or shops cutting multiple runs. A licensed or qualified trade technician typically handles bulk hose installation where proper fitting selection and pressure rating compliance are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-on construction — no clamps required when used with compatible push-on barb fittings\u003c\/li\u003e\n  \u003cli\u003e350 psi working pressure rating for standard compressed air service\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 degrees F to 212 degrees F\u003c\/li\u003e\n  \u003cli\u003eSynthetic rubber construction resists abrasion and maintains flexibility\u003c\/li\u003e\n  \u003cli\u003eBlue color for easy pneumatic line identification\u003c\/li\u003e\n  \u003cli\u003eCut-to-length from bulk coil — sold per 1-foot increment, 25-foot minimum cut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard push-on barb fittings sized for 1\/4 inch inside diameter air hose.

Depressurize and isolate the air line completely before cutting, fitting, or replacing any hose section. Use a clean, square cut to ensure a proper seal when seating hose onto push-on barb fittings. Verify that all fittings and downstream components are rated at or above the system operating pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.5 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: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: Cut-to-length, 25-foot minimum, 575-foot total coil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight (per foot)\u003c\/strong\u003e: 0.087 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: 821FR-4-BLU-RL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543506878770,"sku":"821FR-4-BLU-RL","price":389.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f77651b5b8aa70a4f7c8a9c9f328940_dec896c0-d2b1-48f2-abbb-a8cfd5498c01.jpg?v=1785919644","url":"https:\/\/voomisupply.com\/products\/parker-821fr-4-blu-rl-push-on-air-hose-1-4-in-350-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
