With a 3\/4 inch inside diameter and a 1.0300 inch outside diameter, it handles working pressures up to 250 psi and performs across a temperature range of -40 degrees F to 212 degrees F. Constructed from black synthetic rubber, the hose offers resistance to abrasion and weathering typical of shop and field air supply lines. It is sold in 1-foot increments with a 10-foot minimum cut length and is available from a 200-foot total coil. Minimum order quantity is 10 feet.\u003c\/p\u003e\u003cp\u003eThis hose suits compressed air applications in HVAC, plumbing, and general mechanical service settings. The push-on end connection style eliminates the need for clamps or ferrules during fitting attachment on compatible barb fittings, making it practical for production assembly and field service repairs. The 3\/4 inch ID supports higher-volume air flow demands typical of larger pneumatic tools and equipment supply lines. Licensed tradespeople and shop technicians installing air distribution systems are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch inside diameter for higher-volume compressed air flow\u003c\/li\u003e\n\u003cli\u003e250 psi working pressure rating\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 212 degrees F\u003c\/li\u003e\n\u003cli\u003eBlack synthetic rubber construction for abrasion and weather resistance\u003c\/li\u003e\n\u003cli\u003ePush-on design for tool-free fitting attachment on barb fittings\u003c\/li\u003e\n\u003cli\u003eSold by the foot in 1-foot increments with a 10-foot minimum cut length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with push-on style barb fittings sized for 3\/4 inch ID hose in compressed air service applications.

Depressurize the air supply line completely before cutting, connecting, or disconnecting hose sections. Ensure barb fittings are clean and free of burrs before seating the hose to achieve a secure push-on connection. Verify that the completed assembly does not exceed the 250 psi working pressure rating under operating conditions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 250 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: Black\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 In\u003c\/strong\u003e: 1-foot increments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Cut Length\u003c\/strong\u003e: 10 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Coil Length\u003c\/strong\u003e: 200 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.221 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-12-BLK-RL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542306128178,"sku":"821FR-12-BLK-RL","price":266.56,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f582abe6dc297743479da240ba974485_74f2df0f-efc2-403e-b2b1-4f34329d83e9.jpg?v=1785897559","url":"https:\/\/voomisupply.com\/products\/parker-821fr-12-blk-rl-push-on-air-hose-3-4-in-250-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
