The tubing measures 0.156 inches inner diameter and 0.25 inches outer diameter with a 0.047-inch wall thickness. It carries a working pressure rating of 180 psi and a vacuum rating of 28 inHg, making it suitable for both pressure and suction lines. Shore A 98 hardness indicates a firm yet flexible profile that resists kinking during routing. HVAC technicians, plumbers, and industrial mechanics install this tubing where flexible, durable lines are needed in tight or high-cycle environments.\u003c\/p\u003e\u003cp\u003eThis tubing is suited for residential and light commercial pneumatic control systems, instrument air lines, and fluid transfer assemblies. It performs across a temperature range of -40 to 150 degrees F, supporting both refrigerated and elevated-temperature service conditions. The 0.476-inch minimum bend radius allows tight routing through equipment enclosures and panels. Its abrasion, chemical, cold, heat, and kink resistance make it well matched for demanding service environments where standard PVC tubing falls short. The 1000-foot coil length supports large installation jobs or shop stock for multiple service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e180 psi working pressure with a 3:1 safety factor\u003c\/li\u003e\n\u003cli\u003e28 inHg vacuum rating suitable for suction-side applications\u003c\/li\u003e\n\u003cli\u003eTemperature range of -40 to 150 degrees F for broad service compatibility\u003c\/li\u003e\n\u003cli\u003eShore A 98 hardness provides firm, kink-resistant flexibility\u003c\/li\u003e\n\u003cli\u003e0.476-inch minimum bend radius supports tight routing in enclosures\u003c\/li\u003e\n\u003cli\u003eResistant to abrasion, chemicals, cold, heat, and kinking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with push-to-connect fittings, barb-type fittings, and compression fittings.

Use a sharp, square tubing cutter rather than scissors or a utility knife to ensure a clean, burr-free end for leak-free fitting insertion. Route tubing away from sharp edges or heat sources that could cause abrasion or accelerated wear over time. Installation should follow applicable codes and equipment manufacturer guidelines for pneumatic control and instrument air systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Thickness\u003c\/strong\u003e: 0.047 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1000 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 180 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Rating\u003c\/strong\u003e: 28 inHg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 to 150 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bend Radius\u003c\/strong\u003e: 0.476 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Shore A 98\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensional Tolerance\u003c\/strong\u003e: +\/- 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Factor\u003c\/strong\u003e: 3:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyurethane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 17.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 14.1 inches x 14 inches x 10.25 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73343R1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952178692402,"sku":"73343R1","price":420.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27cec022336d66cb6e5afb4d04fb7b07_48d747dd-3788-45a8-a510-1afe8102b165.jpg?v=1791749058","url":"https:\/\/voomisupply.com\/products\/midland-industries-73343r1-polyurethane-tubing-1-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
