Tigre Usa Inc 1429-251 Reducing Poly Insert Coupling

Product Description

The TIGRE USA INC 1429-251 is a 2-inch by 1-1/2-inch reducing poly insert coupling designed for connecting polyethylene pipe in cold water service applications. This fitting uses a poly-to-poly insert configuration and is secured with stainless steel clamps applied over the PE pipe ends. It is rated under ASTM D-2609 and carries NSF 14 and 16 listings for potable water service. Licensed plumbers and irrigation contractors install this type of fitting in low-pressure water distribution lines where a reduction from 2-inch to 1-1/2-inch PE pipe is required. Fitting modifications of any kind void the manufacturer warranty.

This coupling is suited for residential and light commercial cold water distribution systems using polyethylene pipe. Typical applications include agricultural irrigation laterals, rural water supply lines, and outdoor water service runs where PE pipe transitions between two different diameters. It is not approved for use with compressed air or gases, and it is not listed for installation inside a dwelling. Use is restricted to cold water service only.

Compatibility

Designed for use with polyethylene PE pipe in cold water service applications. Compatible fittings require stainless steel clamps for proper connection. Not intended for use inside dwellings or with compressed air or gas lines.

Installation Notes

Installation is typically performed by licensed plumbers or irrigation professionals familiar with polyethylene pipe systems. Shut off the water supply and depressurize the line completely before cutting pipe or seating insert fittings. Stainless steel clamps must be properly torqued per clamp manufacturer specifications to achieve a leak-free connection on PE pipe. Do not modify the fitting in any way, as doing so voids the warranty and may compromise fitting integrity.
