Tigre Usa Inc 1429-020 Poly Insert Coupling 2 Inches

Product Description

The TIGRE USA INC 1429-020 is a 2-inch poly insert coupling designed for joining polyethylene (PE) pipe in cold water service lines. The fitting uses a poly-to-poly insert configuration and is secured with stainless steel clamps, creating a reliable mechanical connection without solvent cement or heat fusion. This fitting is rated for potable water applications and carries NSF 14 and NSF 16 listings. It is intended for use by plumbers and irrigation professionals working on below-grade or outdoor PE pipe systems where a durable, code-listed coupling is required.

This coupling is suited for residential and light commercial cold water distribution systems that use polyethylene pipe. Typical applications include irrigation mainlines, rural water service laterals, and utility water runs where PE pipe is the specified material. It is not rated for use inside dwellings, and it must not be used with compressed air or any gas service. All installations should follow applicable plumbing codes and the manufacturer's guidelines for clamp torque and pipe preparation.

Key Features

• Poly-to-poly insert design connects directly to PE polyethylene pipe
• Secured with stainless steel clamps for a corrosion-resistant mechanical joint
• NSF 14 and NSF 16 listed for potable cold water service
• ASTM D-2609 listed fitting standard
• Cold water service only — not rated for compressed air, gases, or interior dwelling use
• Fitting modifications void the manufacturer warranty

Compatibility

Designed for use with PE polyethylene pipe in cold water service applications. Compatible pipe and clamp sizes must match the 2-inch insert fitting dimension. Not suitable for hot water, gas, or compressed air systems.

Installation Notes

Installation is typically performed by a licensed plumber or irrigation technician. Shut off the water supply and depressurize the line before cutting or fitting the pipe. Insert the fitting fully into the prepared pipe end and secure each side with appropriately sized stainless steel clamps per the fitting manufacturer's instructions. Do not modify the fitting body, as any alteration voids the warranty and may compromise joint integrity.
