This fitting uses a poly-to-poly insert design, meaning it seats inside the PE pipe bore and is secured with stainless steel clamps. It is rated for potable water service under NSF 14 and NSF 16, and it meets ASTM D-2609 requirements. Plumbers and irrigation technicians typically install this fitting in below-grade or above-grade cold water lines where a reducing connection is needed between two different PE pipe sizes.\u003c\/p\u003e\u003cp\u003eThis coupling is intended for cold water applications only. It is not approved for use with compressed air or gases, and it is not listed for installation inside a dwelling. Typical applications include rural water supply lines, agricultural irrigation systems, and utility water service runs where polyethylene pipe is the standard material. The insert design provides a secure mechanical connection when paired with appropriately sized stainless steel clamps, which are required for proper installation and warranty compliance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces 1.5-inch PE pipe to 1.25-inch PE pipe in a single fitting\u003c\/li\u003e\n\u003cli\u003ePoly insert design seats inside the pipe bore for a secure mechanical fit\u003c\/li\u003e\n\u003cli\u003eRequires stainless steel clamps for connection — clamps not included\u003c\/li\u003e\n\u003cli\u003eNSF 14 and NSF 16 listed for potable cold water service\u003c\/li\u003e\n\u003cli\u003eASTM D-2609 listed for poly insert fittings\u003c\/li\u003e\n\u003cli\u003eCold water service only — not rated for compressed air, gas, or indoor dwelling use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with PE polyethylene pipe in a poly-to-poly reducing insert configuration.

Shut off the water supply and relieve system pressure completely before cutting into any existing line. Secure each end of the insert fitting with correctly sized stainless steel clamps torqued per the clamp manufacturer guidelines — do not substitute hose clamps not rated for PE pipe service. Never use this fitting with compressed air, gas lines, or in any application inside a residential dwelling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Poly Insert x Poly Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Material Compatibility\u003c\/strong\u003e: PE Polyethylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Type\u003c\/strong\u003e: Cold water only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: ASTM D-2609, NSF 14, NSF 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 per unit of measure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TIGRE USA INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1429-212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TIGRE","offers":[{"title":"Default Title","offer_id":51525307072818,"sku":"1429-212","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea12ac14ebc241be478be45d7ebf3a64_576e783a-7351-4435-9db8-23894bcab1a4.jpg?v=1785470243","url":"https:\/\/voomisupply.com\/products\/tigre-usa-inc-1429-212-reducing-poly-insert-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
