Molded from polyoxymethylene (POM), a rigid engineering thermoplastic, this fitting delivers a rated working pressure of 300 psi while resisting moisture, fuels, and many common solvents. It accepts tubing with a 5\/16 inch outside diameter and reduces to a smaller line without requiring ferrules, threads, or clamps. HVAC technicians, plumbers, and industrial maintenance techs use this fitting wherever a fast, reliable tube reduction is needed in a low-bulk installation.\u003c\/p\u003e\n\u003cp\u003eThis fitting suits residential and light commercial pneumatic control lines, compressed air distribution, fluid handling systems, and similar low-to-medium pressure applications where POM construction is compatible with the media. The plug-in design allows a technician to seat the tube with a single straight push, locking it in place for a leak-resistant connection. It is suited for installations where space is tight and quick serviceability is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design — no tools, ferrules, or threads required for tube insertion\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi working pressure\u003c\/li\u003e\n  \u003cli\u003ePolyoxymethylene (POM) body offers high rigidity, dimensional stability, and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eAccepts 5\/16 inch OD tubing — plug-in reducer configuration for line size transitions\u003c\/li\u003e\n  \u003cli\u003eTan color for visual identification in multi-line installations\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight at 0.02 pounds — minimal impact on tubing layout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect reducer fitting for pneumatic control and fluid transfer tubing systems using 5\/16 inch OD tubing. Confirm media and temperature compatibility with POM before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians, plumbers, or qualified maintenance personnel. Before servicing any line, depressurize the system completely and verify pressure has bled to zero. To install, cut tubing square with a clean tube cutter, insert the tube fully into the fitting until it seats and locks. To release, depress the collet ring while pulling the tube straight out — never pull at an angle, as this can deform the collet and cause a leak path.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyoxymethylene (POM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Tan\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: A5RD8-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539017367858,"sku":"A5RD8-MG","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bd4beb2cb79b915fdcaa0a4737622b1.jpg?v=1785832933","url":"https:\/\/voomisupply.com\/products\/parker-a5rd8-mg-push-to-connect-plug-in-reducer-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
