• Anti-Corrosion Finish: Black surface treatment helps reduce rust and visual corrosion in high-moisture environments to extend service life.
• Universal Compatibility: Works with 1in PEX tubing and all standard brass or poly crimp fittings so it fits into typical plumbing workflows.
• Installation Guide: Simple three-step process of slide ring, insert fitting, and use a crimp tool makes installation straightforward for DIYers and pros.
• Job-Ready Pack: Includes 200 rings so you have ample supply for multiple repairs or larger projects without frequent reordering.

Who It's For

The pack is best for plumbers, contractors, and homeowners who regularly work with 1in PEX lines and need a high-volume, consistent crimp solution. Those doing new builds or major renovations will appreciate the quantity and the treated finish for longevity.

Less suitable for occasional single repairs where a much smaller pack would be more economical, or for users who require a different ring material or non-crimp joining methods; these rings assume use with a standard crimp tool and matching fittings.
