This coupling provides a flexible yet secure connection between two clay pipe ends, compensating for minor misalignment and ground movement without rigid mechanical failure. It is typically installed by licensed plumbers or sewer contractors during new construction, rehabilitation, or repair of underground drainage infrastructure. At 3.62 pounds, the coupling is manageable for single-technician installation in confined trench conditions.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and commercial underground sewer and stormwater drain applications where clay pipe is the specified material. Clay-to-clay couplings of this type are commonly used in municipal lateral connections, private sewer laterals, and trenchless rehabilitation scenarios where maintaining the integrity of existing clay pipe runs is required. The Calder-style coupling design accommodates standard clay pipe outside diameters at the 8-inch nominal pipe size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-inch nominal size for clay-to-clay pipe connections\u003c\/li\u003e\n  \u003cli\u003eCalder coupling design provides flexible, shear-resistant joints\u003c\/li\u003e\n  \u003cli\u003eAccommodates minor angular deflection and ground settlement\u003c\/li\u003e\n  \u003cli\u003eLightweight at 3.62 pounds for ease of handling in trench conditions\u003c\/li\u003e\n  \u003cli\u003eCompatible with vitrified clay pipe used in gravity-flow sewer and drain systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation coupling for 8-inch vitrified clay pipe in gravity-flow underground sewer and drainage systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or sewer contractor in accordance with local plumbing codes and IPC requirements for underground drainage systems. The pipe ends should be clean, free of debris, and properly aligned before seating the coupling. Excavate sufficient trench width to allow full coupling engagement and proper bedding support around the joint. Always verify pipe outside diameter compatibility before installation to ensure a proper seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Clay x Clay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Style\u003c\/strong\u003e: Calder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.62 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 70288705010\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: MISSION RUBBER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MR01 88\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MISSION RUBBER","offers":[{"title":"Default Title","offer_id":51396265214258,"sku":"MR01 88","price":54.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834564.png?v=1782828555","url":"https:\/\/voomisupply.com\/products\/mission-rubber-mr01-88-clay-x-clay-calder-coupling-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
