The coupling uses stainless steel bands that tighten to a specified torque to create a leak-proof, chemical-resistant connection. Installation requires only a slotted screwdriver or a 5\/16-inch nut driver or socket, keeping the process straightforward for plumbing professionals working in residential or commercial applications.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for underground and above-grade DWV piping where soil conditions, root intrusion, or chemical exposure are concerns. The strong back design adds structural reinforcement to the coupling body, making it appropriate for transitions between cast iron, plastic (PVC or ABS), and rubber pipe in both new construction and repair scenarios. Licensed plumbers and pipefitters install this type of coupling during rough-in work, sewer lateral repairs, and system tie-ins.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-shear design prevents gasket displacement during tightening\u003c\/li\u003e\n\u003cli\u003eStrong back reinforcement adds rigidity to the coupling body\u003c\/li\u003e\n\u003cli\u003eStainless steel bands torque to 60 inch-pounds for a leak-proof seal\u003c\/li\u003e\n\u003cli\u003eChemical-resistant construction impervious to root intrusion and soil conditions\u003c\/li\u003e\n\u003cli\u003eInstalls with a slotted screwdriver or 5\/16-inch nut driver or socket\u003c\/li\u003e\n\u003cli\u003ePart number, size, and compatible material types are marked directly on the coupling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style universal replacement coupling for 8-inch cast iron, plastic, and rubber DWV pipe connections in residential and commercial plumbing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off flow and relieve any system pressure before cutting into an existing line. Tighten stainless steel bands to 60 inch-pounds using a slotted screwdriver or 5\/16-inch nut driver  -  do not overtighten beyond the specified torque, as this can damage the gasket. Verify pipe ends are clean, deburred, and properly aligned before seating the coupling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 8 x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Non-Shear Strong Back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Torque\u003c\/strong\u003e: 60 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Materials\u003c\/strong\u003e: Cast Iron, Plastic, Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Tool\u003c\/strong\u003e: Slotted screwdriver or 5\/16-inch nut driver or socket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PIPECONX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PCX56-88RCX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MAXIFLEX","offers":[{"title":"Default Title","offer_id":68102893863218,"sku":"PCX56-88RCX","price":123.45,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/pipeconx-pcx56-88rcx-strong-back-coupling-8x8","provider":"Voomi Supply","version":"1.0","type":"link"}
