Tigre Usa Inc 1429-010 Poly Insert Coupling 1 Inch

Product Description

The TIGRE USA INC 1429-010 is a 1-inch poly insert coupling designed for joining polyethylene (PE) pipe in cold water distribution systems. The poly-by-poly configuration accepts PE pipe on both ends and is secured with stainless steel clamps, creating a reliable mechanical connection without solvent cementing. This fitting carries NSF 14 and NSF 61 listings for potable water service and meets ASTM D-2609 standards. It is installed by licensed plumbers and irrigation professionals working on underground or above-grade PE piping systems where a straight inline coupling is required.

This coupling is intended for cold water service only, including potable water supply, irrigation mainlines, and rural water distribution runs using polyethylene pipe. It is not rated for use with compressed air or gases, and is not approved for installation inside a dwelling. Its insert design makes it well suited for agricultural, municipal utility, and landscape irrigation applications where PE pipe is the standard conveyance material.
