Tigre Usa Inc 1429-007 Poly Insert Coupling 3/4 Inch

Product Description

The TIGRE USA INC 1429-007 is a 3/4-inch poly insert coupling designed for joining polyethylene (PE) pipe in cold water supply applications. The fitting uses a barbed poly-to-poly insert connection secured with stainless steel clamps, creating a reliable mechanical joint without solvent cement or heat fusion. This type of fitting is a standard choice for plumbers and irrigation professionals working with PE pipe on water service lines and outdoor distribution systems. It is rated for potable water service under NSF 14 and 16 and meets ASTM D-2609 requirements.

This coupling is intended for cold water service only and is not approved for use with compressed air, gases, or hot water lines. It is not for use inside a dwelling. Typical applications include rural water service laterals, agricultural irrigation headers, and outdoor cold water distribution where PE pipe is the specified material. The poly insert design is well suited to field repairs and extensions of existing PE pipe runs.
