The TIGRE USA INC 1449-010 is a 1-inch PVC plastic insert plug designed for use with polyethylene (PE) pipe in cold water distribution systems. The plug connects to PE pipe using stainless steel clamps, creating a secure, sealed termination point. It is listed under ASTM D-2609 and meets NSF 14 and NSF 16 standards for potable water service. This fitting is installed by licensed plumbers and irrigation technicians working on below-grade or surface-run PE pipe systems. It is rated for cold water service only and must not be used with compressed air, gases, or in dwelling units.
This insert plug is suited for outdoor and agricultural water supply lines, irrigation systems, and utility service connections where polyethylene pipe is the distribution medium. Its poly insert design seats inside the pipe bore, and clamp retention provides a firm mechanical connection. Installers working on potable water systems will find the NSF 14 and NSF 16 listings relevant for code compliance on public or private water service applications. It is sold in packages of 15 units.
Designed for use with polyethylene (PE) pipe in cold water service applications where insert-style fittings with stainless steel clamps are specified.
Installation is performed by licensed plumbers or irrigation contractors following applicable plumbing codes. Shut off water supply and relieve line pressure before installing or removing fittings. Stainless steel clamps must be used to secure the insert fitting to the PE pipe — do not substitute with non-rated fasteners. Fitting modifications of any kind void the manufacturer warranty.
