It features a 1\/4 inch body diameter with a hose barb thread type sized for 3\/8 inch inside diameter hose. Built to the Industrial Interchange standard, it delivers a rated maximum working pressure of 300 psi across a wide operating temperature range of -40 degrees F to 250 degrees F. This coupler is installed by HVAC technicians, industrial maintenance mechanics, and pneumatic system specialists where a reliable, leak-resistant connection between a hose and a quick-disconnect circuit is required.\u003c\/p\u003e\n\u003cp\u003eThe B20-5B belongs to the Parker Series 20 Industrial Interchange family, making it compatible with other Industrial Interchange-style couplers and nipples commonly found in shop air systems, pneumatic tool lines, and light industrial automation. Its hose barb end accepts 3\/8 inch ID flexible pneumatic hose, while the coupler body connects to the mating nipple in a standard Industrial Interchange socket. This fitting suits both permanent and field-serviceable installations in residential and commercial mechanical rooms, job-site air systems, and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial Interchange (Series 20) pattern for broad cross-brand compatibility\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and durability in pneumatic service\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eHose barb end sized for 3\/8 inch ID hose — no ferrule or clamp fitting required for many applications\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.49 inches with 0.75 inch hex for wrench engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation coupler for Industrial Interchange Series 20 pneumatic quick-disconnect systems accepting a 1\/4 inch body coupler with a 3\/8 inch ID hose barb connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified technician or pipefitter. Before servicing any pneumatic line, depressurize the system completely and bleed residual air pressure from the circuit. Slide the hose barb end fully into the 3\/8 inch ID hose and secure with an appropriate hose clamp rated for the working pressure. Use the 0.75 inch hex on the coupler body for wrench tightening; do not over-tighten or apply torque beyond what is needed to seat the fitting. Verify the completed connection is leak-free by bringing the system back to working pressure and inspecting with a suitable leak-detection method.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHose Inside Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Hose Barb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 20 Industrial Interchange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.49 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.189 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\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: B20-5B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543117365554,"sku":"B20-5B","price":42.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6220e8596906b4dc02f67d4865b55016.jpg?v=1785915861","url":"https:\/\/voomisupply.com\/products\/parker-b20-5b-pneumatic-hose-coupling-1-4-in-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
