With a 1\/4 inch inside diameter and a 0.5 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 synthetic rubber, it delivers reliable flexibility and durability in demanding shop and field environments. It is sold by the foot in 25-foot minimum cut lengths from a 575-foot master coil, making it practical for contractors and service shops that need exact run lengths without waste.\u003c\/p\u003e\u003cp\u003eThis hose is suited for pneumatic tool lines, air supply drops, and general compressed air routing in commercial and light industrial settings. The push-on design eliminates the need for hose clamps at the fitting connection, speeding up assembly for HVAC technicians, plumbers, pipefitters, and general mechanical contractors. The green color aids visual identification in multi-line installations. No end connections are included; field-installed push-on fittings are required to complete the assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-on construction allows fast, clamp-free fitting attachment\u003c\/li\u003e\n\u003cli\u003e350 psi working pressure rated for compressed air service\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 degrees F to 212 degrees F suits a wide range of environments\u003c\/li\u003e\n\u003cli\u003eSynthetic rubber construction provides flexibility and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eGreen color supports easy line identification in multi-hose installations\u003c\/li\u003e\n\u003cli\u003eSold by the foot in 25-foot minimum increments from a 575-foot coil\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard push-on pneumatic fittings sized for 1\/4 inch ID hose in compressed air distribution systems.

Depressurize and lock out the air supply before cutting or connecting hose segments. Use a clean, square cut to ensure a proper push-on fitting seal. Confirm that all fittings and system components are rated to meet or exceed the 350 psi working pressure of this hose.\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: 0.5 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: Green\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\u003eWeight (per foot)\u003c\/strong\u003e: 0.087 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25 feet\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-GRN-RL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538983878962,"sku":"821FR-4-GRN-RL","price":429.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1e70749da22adfc939cd8dd84d77f3d_87c289ac-7ce2-44f8-a8e6-d53b3c69a119.jpg?v=1785831771","url":"https:\/\/voomisupply.com\/products\/parker-821fr-4-grn-rl-push-on-air-hose-1-4-in-350-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
