The diaphragm is the sealing component inside the valve body that controls water flow by flexing open and closed in response to pressure changes. Over time, diaphragms degrade, crack, or develop leaks that prevent the valve from shutting off cleanly or maintaining consistent flow. This assembly restores the sealing surface and returns the valve to reliable operation without requiring full valve body replacement. It is installed by irrigation technicians and experienced maintenance crews during routine valve service or emergency repair.\u003c\/p\u003e\n\u003cp\u003eThis diaphragm assembly is suited for residential and light commercial irrigation systems using 1-inch Irritrol 100 Series valves. It is a common maintenance part for in-ground irrigation systems where valve diaphragms are subject to UV exposure, water quality degradation, and pressure cycling. Keeping a spare r-1308 on hand reduces system downtime when a valve fails mid-season. It is also appropriate for scheduled preventive maintenance programs where diaphragms are replaced at set service intervals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect-fit replacement for 1-inch Irritrol 100 Series irrigation valves\u003c\/li\u003e\n  \u003cli\u003eRestores valve sealing surface to stop leaks and maintain consistent water flow\u003c\/li\u003e\n  \u003cli\u003eAllows valve body to remain in place — no full valve replacement needed\u003c\/li\u003e\n  \u003cli\u003eMinimal tools required for field installation\u003c\/li\u003e\n  \u003cli\u003eSuitable for both residential and light commercial irrigation applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit OEM-style replacement for 1-inch Irritrol 100 Series irrigation valves.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eIrrigation technicians or qualified maintenance personnel should shut off the water supply and relieve system pressure before servicing the valve. Remove the valve bonnet, extract the old diaphragm assembly, and seat the new r-1308 assembly before reassembling the bonnet. Inspect bonnet screws and other fasteners during replacement and replace any that show wear or corrosion. Follow all applicable local codes for irrigation system service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Valve Series\u003c\/strong\u003e: Irritrol 100 Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential and light commercial irrigation\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: IRRITROL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: r-1308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRRITROL","offers":[{"title":"Default Title","offer_id":51150760575282,"sku":"R-1308","price":35.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305986311.png?v=1778617906","url":"https:\/\/voomisupply.com\/products\/irritrol-r-1308-diaphragm-assembly-1-inch-100-series","provider":"Voomi Supply","version":"1.0","type":"link"}
