Tigre Usa Inc 1429-131 Reducing Poly Insert Coupling

Product Description

The TIGRE USA INC 1429-131 is a 1-inch by 3/4-inch reducing poly insert coupling designed for connecting polyethylene (PE) pipe in cold water service applications. The fitting uses a poly-to-poly insert design and is secured with stainless steel clamps, creating a reliable mechanical connection without solvent cement or heat fusion. Rated to ASTM D-2609 and listed under NSF 14 and NSF 16 for potable water service, this coupling meets recognized standards for water distribution fittings. It is suited for irrigation systems, rural water lines, and similar cold water distribution work where PE pipe is the material of choice.

This coupling is intended for cold water service only and is not approved for use with compressed air, gases, or hot water. It is also not approved for installation inside a dwelling. Typical applications include agricultural irrigation, rural water supply lines, and outdoor cold water distribution systems where polyethylene pipe is used. Installation requires stainless steel clamps to secure the insert fitting to the PE pipe. Any modifications made to the fitting void the manufacturer warranty.

Key Features

• Reducing insert design connects 1-inch PE pipe to 3/4-inch PE pipe in a single fitting
• Poly-to-poly construction compatible with standard polyethylene insert fitting installation methods
• Secured with stainless steel clamps for a durable mechanical connection
• ASTM D-2609 listed construction standard
• NSF 14 and NSF 16 listed for potable cold water service
• Cold water only — not rated for compressed air, gas, or interior dwelling use

Compatibility

Designed for use with polyethylene (PE) pipe in cold water distribution applications. Compatible with standard poly insert fitting installation using stainless steel clamps. Not for use inside dwellings or with compressed air or gases.

Installation Notes

Installation is typically performed by plumbers or irrigation contractors working with polyethylene pipe systems. Before beginning work, shut off the water supply and relieve any pressure in the line. Insert the fitting fully into the PE pipe ends and secure each side with appropriately sized stainless steel clamps tightened per clamp manufacturer guidelines. Do not modify the fitting in any way, as modifications void the warranty and may compromise the integrity of the potable water system.
